  • Can't Install libcurl PHP on Ubuntu Linux

    - by FranticPedantic
    I am trying to use the new facebook api and it requires libcurl PHP. I used sudo apt-get install php5-curl sudo apachectl -k restart And it didn't work. I get the same error and the phpinfo() page says nothing about libcurl. The source of this problem is probably that I built some of the tools from source (apache2, php), but then I got bored so installed a lot of the extensions with the package manager. But I'm not exactly how to go about diagnosing the point of failure. The apt-get install for curl definitely worked, and can be found in /usr/lib/php5/20060613/curl.so I think a lot of my confusion stems from not knowing which files go where, and what purpose they have. Any help would be appreciated, and please tell me if I need to provide more information. edit: The specific error I get is: Exception: Facebook needs the CURL PHP extension. from line if (!function_exists('curl_init')) { throw new Exception('Facebook needs the CURL PHP extension.'); } Ubuntu: 9.10 PHP: 5.2.13 Loaded Configuration File: /etc/php5/apache2/php.ini

  • Printing out this week's dates in perl

    - by ABach
    Hi folks, I have the following loop to calculate the dates of the current week and print them out. It works, but I am swimming in the amount of date/time possibilities in perl and want to get your opinion on whether there is a better way. Here's the code I've written: #!/usr/bin/env perl use warnings; use strict; use DateTime; # Calculate numeric value of today and the # target day (Monday = 1, Sunday = 7); the # target, in this case, is Monday, since that's # when I want the week to start my $today_dt = DateTime->now; my $today = $today_dt->day_of_week; my $target = 1; # Create DateTime copies to act as the "bookends" # for the date range my ($start, $end) = ($today_dt->clone(), $today_dt->clone()); if ($today == $target) { # If today is the target, "start" is already set; # we simply need to set the end date $end->add( days => 6 ); } else { # Otherwise, we calculate the Monday preceeding today # and the Sunday following today my $delta = ($target - $today + 7) % 7; $start->add( days => $delta - 7 ); $end->add( days => $delta - 1 ); } # I clone the DateTime object again because, for some reason, # I'm wary of using $start directly... my $cur_date = $start->clone(); while ($cur_date <= $end) { my $date_ymd = $cur_date->ymd; print "$date_ymd\n"; $cur_date->add( days => 1 ); } As mentioned, this works - but is it the quickest/most efficient/etc.? I'm guessing that quickness and efficiency may not necessarily go together, but your feedback is very appreciated.

  • PyQt Drag and Drop - Nothing happens

    - by Umang
    Hi, I'm trying to get drop a file onto a Window (I've tried the same thing with a QListWidget without success there too) test.py: #! /usr/bin/python # Test from PyQt4 import QtCore, QtGui import sys from qt_test import Ui_MainWindow class MyForm(QtGui.QMainWindow, Ui_MainWindow): def __init__(self, parent=None): QtGui.QWidget.__init__(self, parent) self.setupUi(self) self.__class__.dragEnterEvent = self.DragEnterEvent self.__class__.dragMoveEvent = self.DragEnterEvent self.__class__.dropEvent = self.drop self.setAcceptDrops(True) print "Initialized" self.show() def DragEnterEvent(self, event): event.accept() def drop(self, event): link=event.mimeData().text() print link def main(): app = QtGui.QApplication(sys.argv) mw = MyForm() sys.exit(app.exec_()) if __name__== "__main__": main() And here's qt_test.py # -*- coding: utf-8 -*- # Form implementation generated from reading ui file 'untitled.ui' # # Created: Thu May 20 12:23:19 2010 # by: PyQt4 UI code generator 4.6 # # WARNING!

Do you know what I'm doing wrong? Thanks!

    - by GustlyWind
    I have a module written in servlets and needs to be recently moved to velocity framework So in the process I am rewriting the web.xml to create velocity servlet object whcih calls our original servlet . Now if this has to be moved to <servlet> <servlet-name>VeloServlet</servlet-name> <servlet-class>org.apache.velocity.tools.view.servlet.VelocityViewServlet</servlet-class> </servlet> How can we acheive this and what are all changes need to use the existing servlet as it is. My Existing servlet looks like <servlet-name>DataBridgeServlet</servlet-name> <servlet-class>com.jda.pwm.databridge.framework.common.DataBridgeServlet</servlet-class> <init-param> <param-name>jda.databridge.config.path</param-name> <param-value>d:/usr/databridge/conf</param-value> </init-param> This is loaded using the url http://localhost:8080/databridge/databridgeservlet So in the newer case how velocity servlet calls this servlet

  • How to extract paragaph and selected lines with Perl

    - by neversaint
    I have a text that looks like this. What I want to do is to extract the whole paragraph under the section "Aceview summary" until the line that starts with "Please quote". extract the line that starts with "The closest human gene". And store them into array with two elements. However I am stuck with the following script logic. What's the right way to achieve that? #!/usr/bin/perl -w my $INFILE_file_name = $file; # input file name open ( INFILE, '<', $INFILE_file_name ) or croak "$0 : failed to open input file $INFILE_file_name : $!\n"; my @allsum; while ( <INFILE> ) { chomp; my $line = $_; my @temp1 = (); if ( $line =~ /^ AceView summary/ ) { print "$line\n"; push @temp1, $line; } elsif( $line =~ /Please quote/) { push @allsum, [@temp1]; @temp1 = (); } } close ( INFILE ); # close input file

  • Why do I get "Error 6060" when I try to use DBD::Advantage with a 64-bit perl on Linux?

    - by WarheadsSE
    I realize that I am attempting to go beyond the "supported" behavior of the manf's released drivers for Perl, after all they have only released it in package with x86 .so's. However, since I cannot use their package with x64 Perl on a RHEL 5.4 x86_64 box, and maintaining a seperate install of x86 Perl just for this one package, I have made an attempt to get this puppy working thanks to released 64-bit .so's that accompany other driver packages for Advantage. What I have done to this point: download beta 10 DBI drivers, in 32 download beta 10 PHP extension (it contains 32 and x86_64) copy the required DLLs into the ads-lib location (eg /usr/local/ads/lib64) compile the Perl DBI driver with the path to the lib64's .so's Good compilation, good install, good use. The problem is that I always get : failed: [iAnywhere Solutions][Advantage SQL][ASA] Error 6060: Advantage Database Server not available on specified server. axServerConnect (SQL-HY000)(DBD: db_login/SQLConnect err=-1) Does anyone have any ideas? EDIT: fixed package name in post title EDIT: Updated title. It appears that it's not just the x64 perl, but the RHEL 5.4 underneath that may be interfering. As commented below, I managed to shoe-horn a x86 perl onto the system, and compile the DBD::Advantage 9.99, and later replacing that with 9.10, and none of these x86 would connect either. Neither library (9.99 or 9.10) in either bit-edness will connect from this x86_64 server to the windows server's UNC path. I have successfully mounted this share without problems, but still I cannot seem to connect to the 9.1. I have tried: \hostname\PATH \FQDN\PATH \IP\PATH and all of these variations with the port (default) 6262 included. My windows machine connects fine, with both 9.1 and 9.99 from strawberry perl.

  • Problem with RVM and gem that has an executable

    - by djhworld
    Hi there, I've recently made the plunge to use RVM on Ubuntu. Everything seems to have gone swimmingly...except for one thing. I'm in the process of developing a gem of mine that has a script placed within its own bin/ directory, all of the gemspec and things were generated by Jeweler. The bin/mygem file contains the following code: - #!/usr/bin/env ruby begin require 'mygem' rescue LoadError require 'rubygems' require 'mygem' end app = MyGem::Application.new app.run That was working fine on the system version of Ruby. Now...recently I've moved to RVM to manage my ruby versions a bit better, except now my gem doesn't appear to be working. Firstly I do this: - rvm 1.9.2 Then I do this: - rvm 1.9.2 gem install mygem Which installs fine, except...when I try to run the command for mygem mygem I just get the following exception: - daniel@daniel-VirtualBox:~$ mygem <internal:lib/rubygems/custom_require>:29:in `require': no such file to load -- mygem (LoadError) from <internal:lib/rubygems/custom_require>:29:in `require' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/gems/mygem-0.1.4/bin/mygem:2:in `<top (required)>' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/bin/mygem:19:in `load' from /home/daniel/.rvm/gems/ruby-1.9.2-p136/bin/mygem:19:in `<main>'mygem NOTE: I have a similar RVM setup on MAC OSX and my gem works fine there so I think this might be something to do with Ubuntu?

  • Connecting to SFTP service via Java Runtime process

    - by ohseekay
    Under my project, I have a Java class file, inside of which I have a routine which executes the following external SFTP script file: #!/bin/sh echo "cd AV/OASIS" >> sftp echo "put $1 $2" >> sftp echo "get AV/OASIS/$2 $3$2" >> sftp echo "bye" >> sftp /usr/local/bin/sftp -b sftp id@domain cat /dev/null > sftp exit 0 The Java code which executes the script file is as below: String script = "full path of script"; Process p = Runtime.getRuntime().exec(script + " " + param1 + " " + param2 + " " + param3); However, I'm not sure why, but the log generated by the class file always shows the error "Host key verification failed. Connection closed." I'd isolated that line in the script which connected to the remote machine, and ran it on the local machine (where this class file and script file are stored), and the command executed successfully I'd manually run the command which the Java class file will execute and it also tested okay: $ script.sh param1 param2 param3 I'd tried to look up the error message on the Internet, and apparently it seems to have something to do with known_hosts. Could this be the reason, or is there something else I'm missing? Thanks so much!

  • Problem with fork exec kill when redirecting output in perl

    - by Edu
    I created a script in perl to run programs with a timeout. If the program being executed takes longer then the timeout than the script kills this program and returns the message "TIMEOUT". The script worked quite well until I decided to redirect the output of the executed program. When the stdout and stderr are being redirected, the program executed by the script is not being killed because it has a pid different than the one I got from fork. It seems perl executes a shell that executes my program in the case of redirection. I would like to have the output redirection but still be able to kill the program in the case of a timeout. Any ideas on how I could do that? A simplified code of my script is: #!/usr/bin/perl use strict; use warnings; use POSIX ":sys_wait_h"; my $timeout = 5; my $cmd = "very_long_program 1>&2 > out.txt"; my $pid = fork(); if( $pid == 0 ) { exec($cmd) or print STDERR "Couldn't exec '$cmd': $!"; exit(2); } my $time = 0; my $kid = waitpid($pid, WNOHANG); while ( $kid == 0 ) { sleep(1); $time ++; $kid = waitpid($pid, WNOHANG); print "Waited $time sec, result $kid\n"; if ($timeout > 0 && $time > $timeout) { print "TIMEOUT!\n"; #Kill process kill 9, $pid; exit(3); } } if ( $kid == -1) { print "Process did not exist\n"; exit(4); } print "Process exited with return code $?\n"; exit($?); Thanks for any help.

  • Rails: Oracle constraint violation

    - by justinbach
    I'm doing maintenance work on a Rails site that I inherited; it's driven by an Oracle database, and I've got access to both development and production installations of the site (each with its own Oracle DB). I'm running into an Oracle error when trying to insert data on the production site, but not the dev site: ActiveRecord::StatementInvalid (OCIError: ORA-00001: unique constraint (DATABASE_NAME.PK_REGISTRATION_OWNERSHIP) violated: INSERT INTO registration_ownerships (updated_at, company_ownership_id, created_by, updated_by, registration_id, created_at) VALUES ('2006-05-04 16:30:47', 3, NULL, NULL, 2920, '2006-05-04 16:30:47')): /usr/local/lib/ruby/gems/1.8/gems/activerecord-oracle-adapter-1.0.0.9250/lib/active_record/connection_adapters/oracle_adapter.rb:221:in `execute' app/controllers/vendors_controller.rb:94:in `create' As far as I can tell (I'm using Navicat as an Oracle client), the DB schema for the dev site is identical to that of the live site. I'm not an Oracle expert; can anyone shed light on why I'd be getting the error in one installation and not the other? Incidentally, both dev and production registration_ownerships tables are populated with lots of data, including duplicate entries for country_ownership_id (driven by index PK_REGISTRATION_OWNERSHIP). Please let me know if you need more information to troubleshoot. I'm sorry I haven't given more already, but I just wasn't sure which details would be helpful.

  • Best terminal environment for Cygwin/Windows?

    - by Anders Sandvig
    Today I run Cygwin with rxvt using the following startup line: rxvt -bg black -sl 8192 -fg white -sr -g 150x56 -fn "Fixedsys" -e /usr/bin/bash --login -i This gives me a resizeable native Windows window which is much better than the standard "DOS box" the default cygwin.bat provides. However, the current configuration does have a couple of issues: I am not able to enter non-ASCII characters into the terminal window (i.e. æ, ø, å and Æ, Ø, Å, which I use semi-frequently. In fact, the terminal will not even accept them when I paste them into the window. If I paste a string like "bølle" (Norwegian for "bulley"), all I get is "blle". I am not able to render UTF-8 character, they only show as ?, even if they are supported by the font (i.e. when rendering the same characters in ISO-8859-1 they show just fine.). I am running English Windows Vista with locale and keyboard layout set to Norwegian (ISO-8859-1 character set?), but I've had the exact same issue on Windows 2000 and XP. Anyone knows how to fix this (i.e. a better way to configure rxvt)? Apart from the issues mentioned above, I'm very happy with rxvt, so if I find a way to resolve them I'd like to continue using it. However, if the issues are not (easily) solvable, are the any other good terminal solutions for Cygwin? Update The solution provided by Andy and Mattias (editing the .inputrc file) did solve the input problem, but output rendering is still an issue. Output is fine when I render in ISO-8859-1, but when using UTF-8 I only get ? for non-ASCII characters. This behavior is consistent between rxvt, urxvt (under Cygwin XFree X Server), mintty and PuttyCyg. Is there a similar configuration file where output encoding can be set (i.e. the equivalent of setting output locale on a Linux system)?

  • How to catch a carp-warning?

    - by sid_com
    I tried to catch a carp-warning ( carp "$start is $end" if (warnings::enabled()); ) with eval but it didn't work, so I looked in the eval-documentation and I discovered, that eval catches only syntax-errors, run-time-errors or executed die-statements. How could I catch a carp-warning? #!/usr/bin/env perl use warnings; use strict; use 5.012; use List::Util qw(max min); use Number::Range; my @array; my $max = 20; print "Input (max $max): "; my $in = <>; $in =~ s/\s+//g; $in =~ s/(?<=\d)-/../g; eval { my $range = new Number::Range( $in ); @array = sort { $a <=> $b } $range->range; }; if ( $@ =~ /\d+ is > \d+/ ) { die $@ }; # catch the carp-warning doesn't work die "Input greater than $max not allowed $!" if defined $max and max( @array ) > $max; die "Input '0' or less not allowed $!" if min( @array ) < 1; say "@array";

  • How to include frameset under CGI.pm

    I want to have a cgi-script that does two things. Take the input from a form. Generate results base on the input values on a frame. Primarily I want the frame exist only after the results is generated/printed. Below is the simplified code of what I want to do. But somehow it doesn't work. What's the right way to do it? #!/usr/local/bin/perl use CGI ':standard'; print header; print start_html('A Simple Example'), h1('A Simple Example'), start_form, "What's your name?

  • How to poll a file in /sys

    - by Bjoern
    Hi, I am stuck reading a file in /sys/ which contains the light intensity in Lux of the ambient light sensor on my Nokia N900 phone. See thread on talk.maemo.org here I tried to use pyinotify to poll the file but this looks some kind of wrong to me since the file is alway "process_IN_OPEN", "process_IN_ACCESS" and "process_IN_CLOSE_NOWRITE" I basically want to get the changes ASAP and if something changed trigger an event, execute a class... Here's the code I tried, which works, but not as I expected (I was hoping for process_IN_MODIFY to be triggered): #!/usr/bin/env python # -*- coding: utf-8 -*- # import os, time, pyinotify import pyinotify ambient_sensor = '/sys/class/i2c-adapter/i2c-2/2-0029/lux' wm = pyinotify.WatchManager() # Watch Manager mask = pyinotify.ALL_EVENTS def action(self, the_event): value = open(the_event.pathname, 'r').read().strip() return value class EventHandler(pyinotify.ProcessEvent): def process_IN_ACCESS(self, event): print "ACCESS event:", action(self, event) def process_IN_ATTRIB(self, event): print "ATTRIB event:", action(self, event) def process_IN_CLOSE_NOWRITE(self, event): print "CLOSE_NOWRITE event:", action(self, event) def process_IN_CLOSE_WRITE(self, event): print "CLOSE_WRITE event:", action(self, event) def process_IN_CREATE(self, event): print "CREATE event:", action(self, event) def process_IN_DELETE(self, event): print "DELETE event:", action(self, event) def process_IN_MODIFY(self, event): print "MODIFY event:", action(self, event) def process_IN_OPEN(self, event): print "OPEN event:", action(self, event) #log.setLevel(10) notifier = pyinotify.ThreadedNotifier(wm, EventHandler()) notifier.start() wdd = wm.add_watch(ambient_sensor, mask) wdd time.sleep(5) notifier.stop() Thanks for any hints, suggestions and examples Kind regards Bjoern

  • Perl cron job stays running

    - by Dylan
    I'm currently using a cron job to have a Perl script that tells my Arduino to cycle my aquaponics system and all is well, except the Perl script doesn't die as intended.

It runs fine from the command line and also interprets the 'cycle' argument fine. When it runs in cron it runs fine, however, the process never dies and while each process doesn't continue to cycle the system it does seem to be looping in some way due to the fact that it ups my system load very quickly. If you'd like more information, just ask.

    hi expert, i'm having task to scan wifi at specific interval and send it to the server, i've it in python and its works fine when i run manually, then build it to package and when run there is no progress at all, i already ask this question before at http://stackoverflow.com/questions/2735410/python-scritp-problem-once-build-and-package-it, then, i re-modify my code as below, then i found that thread is not functioning once i build, #!/usr/bin/env python import subprocess,threading,... configFile = open('/opt/Jemapoh_Wifi/config.txt', 'r') url = configFile.readline().strip() intervalTime = configFile.readline().strip() status = configFile.readline().strip() print "url "+url print "intervalTime "+intervalTime print "Status "+status.strip() def getMacAddress(): proc = subprocess.Popen('ifconfig -a wlan0 | grep HWaddr | sed \'/^.*HWaddr */!d; s///;q\'', shell=True, stdout=subprocess.PIPE, ) macAddress = proc.communicate()[0].strip() return macAddress def getTimestamp(): from time import strftime timeStamp = strftime("%Y-%m-%d %H:%M:%S") return timeStamp def scanWifi(): try: print "Scanning..." proc = subprocess.Popen('iwlist scan 2>/dev/null', shell=True, stdout=subprocess.PIPE, ) stdout_str = proc.communicate()[0] stdout_list=stdout_str.split('\n') essid=[] rssi=[] preQuality=[] for line in stdout_list: line=line.strip() match=re.search('ESSID:"(\S+)"',line) if match: essid.append(match.group(1)) match=re.search('Quality=(\S+)',line) if match: preQuality.append(match.group(1)) for qualityConversion in preQuality: qualityConversion = qualityConversion.split()[0].split('/') temp = str(int(round(float(qualityConversion[0]) / float(qualityConversion[1]) * 100))).rjust(2) rssi.append(temp) dataToPost = '{"userId":"' + getMacAddress() + '","timestamp":"' + getTimestamp() + '","wifi":[' for no in range(len(essid)): dataToPost += '{"ssid":"' + essid[no] + '","rssi":"' + rssi[no] + '"}' if no+1 == len(essid): pass else: dataToPost += ',' dataToPost += ']}' query_args = {"data":dataToPost} request = urllib2.Request(url) request.add_data(urllib.urlencode(query_args)) request.add_header('Content-Type', 'application/x-www-form-urlencoded') print "Waiting for server response..." print urllib2.urlopen(request).read() print "Data Sent @ " + getTimestamp() print "------------------------------------------------------" t = threading.Timer(int(intervalTime), scanWifi).start() except Exception, e: print e t = threading.Timer(int(intervalTime), scanWifi) t.start() once build, its not reaching the thread, do can anyone help, why the thread is not working after build thanks

  • How to override the default init.tcl

    - by Sean Murphy
    I'm working on a project where I want to make use of TCL as the command interpreter. I have a working c library object which I can load from within the tcl shell but my problem is finding a way to automatically do this while starting a tclsh. Essentially my ultimate goal is to be able to run a script and have it load my library and run some initial startup tcl code before dropping me back to the tclsh command prompt in interactive mode. e.g. tclsh -f myscript.tcl --then-switch-to-interactive or EXPORT TCLINIT=myscript.tcl tclsh The basic goal is to avoid having to distribute tclsh but rather rely in local user installations of tcl. All I would like to distribute is my library, a startup script and a shell command to launch the tclsh with the library preloaded. I've tried using the environment variables TCLINIT and TCL_LIBRARY but they seem to have no effect. The only workable solutions I've found so far are to add "source myscript.tcl" to either the end of /usr/share/tcltk/tcl8.5.init.tcl or ~/.tclshrc However both of these "solutions" are non perfect as they require modification of the default users workspace. It strikes me that there must be a way to handle this in TCL, but my research so far hasn't yielded anything. Does anyone have any suggestions?

  • How can I change some specific carps into croaks in Perl?

    - by sid_com
    I tried to catch a carp-warning: carp "$start is > $end" if (warnings::enabled()); ) with eval {} but it didn't work, so I looked in the eval documentation and I discovered, that eval catches only syntax-errors, run-time-errors or executed die-statements. How could I catch a carp warning? #!/usr/bin/env perl use warnings; use strict; use 5.012; use List::Util qw(max min); use Number::Range; my @array; my $max = 20; print "Input (max $max): "; my $in = <>; $in =~ s/\s+//g; $in =~ s/(?<=\d)-/../g; eval { my $range = new Number::Range( $in ); @array = sort { $a <=> $b } $range->range; }; if ( $@ =~ /\d+ is > \d+/ ) { die $@ }; # catch the carp-warning doesn't work die "Input greater than $max not allowed $!" if defined $max and max( @array ) > $max; die "Input '0' or less not allowed $!" if min( @array ) < 1; say "@array";

  • ruby comma operator and step question

    - by ryan_m
    so, i'm trying to learn ruby by doing some project euler questions, and i've run into a couple things i can't explain, and the comma ?operator? is in the middle of both. i haven't been able to find good documentation for this, maybe i'm just not using the google as I should, but good ruby documentation seems a little sparse . . . 1: how do you describe how this is working? the first snippet is the ruby code i don't understand, the second is the code i wrote that does the same thing only after painstakingly tracing the first: #what is this doing? cur, nxt = nxt, cur + nxt #this, apparently, but how to describe the above? nxt = cur + nxt cur = nxt - cur 2: in the following example, how do you describe what the line with 'step' is doing? from what i can gather, the step command works like (range).step(step_size), but this seems to be doing (starting_point).step(ending_point, step_size). Am i right with this assumption? where do i find good doc of this? #/usr/share/doc/ruby1.9.1-examples/examples/sieve.rb # sieve of Eratosthenes max = Integer(ARGV.shift || 100) sieve = [] for i in 2 .. max sieve[i] = i end for i in 2 .. Math.sqrt(max) next unless sieve[i] (i*i).step(max, i) do |j| sieve[j] = nil end end puts sieve.compact.join(", ")

  • How to manage multiple python versions ?

    - by Gyom
    short version: how can I get rid of the multiple-versions-of-python nightmare ? long version: over the years, I've used several versions of python, and what is worse, several extensions to python (e.g. pygame, pylab, wxPython...). Each time it was on a different setup, with different OSes, sometimes different architectures (like my old PowerPC mac). Nowadays I'm using a mac (OSX 10.6 on x86-64) and it's a dependency nightmare each time I want to revive script older than a few months. Python itself already comes in three different flavours in /usr/bin (2.5, 2.6, 3.1), but I had to install 2.4 from macports for pygame, something else (cannot remember what) forced me to install all three others from macports as well, so at the end of the day I'm the happy owner of seven (!) instances of python on my system. But that's not the problem, the problem is, none of them has the right (i.e. same set of) libraries installed, some of them are 32bits, some 64bits, and now I'm pretty much lost. For example right now I'm trying to run a three-year-old script (not written by me) which used to use matplotlib/numpy to draw a real-time plot within a rectangle of a wxwidgets window. But I'm failing miserably: py26-wxpython from macports won't install, stock python has wxwidgets included but also has some conflict between 32 bits and 64 bits, and it doesn't have numpy... what a mess ! Obviously, I'm doing things the wrong way. How do you usally cope with all that chaos ?e

  • Can't get syntax on to work in my gvim.

    - by user198553
    (I'm new to Linux and Vim, and I'm trying to learn Vim but I'm having some issues with it that I can't seen do fix) I'm in a Linux installation (Ubuntu 8.04) that I can't update, using Vim 7.1.138. My vim installation is in /usr/share/vim/vim71/. /home/user/ My .vimrc file is in /home/user/.vimrc, as follows: fun! MySys() return "linux" endfun set runtimepath=~/.vim,$VIMRUTNTIME source ~/.vim/.vimrc And then, in my /home/user/.vim/.vimrc: " =============== GENERAL CONFIG ============== set nocompatible syntax on " =============== ENCODING AND FILE TYPES ===== set encoding=utf8 set ffs=unix,dos,mac " =============== INDENTING =================== set ai " Automatically set the indent of a new line (local to buffer) set si " smartindent (local to buffer) " =============== FONT ======================== " Set font according to system if MySys() == "mac" set gfn=Bitstream\ Vera\ Sans\ Mono:h13 set shell=/bin/bash elseif MySys() == "windows" set gfn=Bitstream\ Vera\ Sans\ Mono:h10 elseif MySys() == "linux" set gfn=Inconsolata\ 14 set shell=/bin/bash endif " =============== COLORS ====================== colorscheme molokai " ============== PLUGINS ====================== " -------------- NERDTree --------------------- :noremap ,n :NERDTreeToggle<CR> " =============== DIRECTORIES ================= set backupdir=~/.backup/vim set directory=~/.swap/vim ...fact is the command syntax on is not working, neither in vim or gvim. And the strange thing is: If I try to set the syntax using the gvim toolbat, it works. Then, in normal mode in gvim, after activating using the toolbar, using the code :syntax off, it works, and just after doing this trying to do :syntax on doesn't work!! What's going on? Am I missing something?

  • Issues Deploying ROOT Context in Tomcat6

    - by Josh K
    I'm working on getting an application deployed to the ROOT ("/") context in my Tomcat 6 instance. Here's what has been done: Defined another virtual host (domain.com) Created the respective folder (/etc/tomcat6/Catalina/domain.com) Set it to auto deploy WAR's Set appBase to CATALINA_BASE/domainapps and created respective folder Copied manager.xml from localhost to domain.com. Now I'm trying to deploy into the ROOT context by uploading a ROOT.war to CATALINA_BASE/domainapps. This isn't working. I don't get any exceptions thrown, but the stock ROOT page ("It works !") stays up. I have successfully deployed it into another context (by uploading domainapp.war and viewing at /domainapp), but not ROOT. Re-reading the Virtual Host setup it makes reference to CATALINA_HOME and CATALINA_BASE. My CATALINA_HOME is at /usr/share/tomcat6/domainapp while CATALINA_BASE is /var/lib/tomcat6. Which should I be using for what? Currently haven't touched CATALINA_HOME but will try messing with a few things there. A better question might be what is the generally accepted flow taken to setup a new Tomcat instance and deploy an application to the root context.
