• Replacing xcode with macports software

  - by Feynman

  I have been trying to replace everything in xcode with stuff I can get from macports. So far, I installed xcode, then macports, then used macports to install gcc, gcc_select, gmake, elf-bintools, bintools, arm-bintools (just to be sure I replaced all the bintools), and then uninstalled all of xcode. I then linked /usr/bin/make with /opt/local/bin/gmake and used gcc_select to select gcc44--the one from macports. I also exported all the bintool executable paths into the .profile path. I was sure this would work (although I should have known better after working on it for 48 hours straight), but nothing will configure, and the log files all have the common error: :info:configure configure: error: C compiler cannot create executables I have a feeling it has something to do with libraries, but I am really not sure. I use a mac 10.5.8. If this is truely 'impossible', what parts of xcode to I need for macports to work? For example, I can uninstall the xcode folder without a problem.

• how to run fastcgi

  - by joels

  I have fastcgi installed and running. I downloaded a developerkit from fastcgi.com. It had some examples in it. One of the example files echos some stuff. It required a .libs and a .deps I put those folders along with a echo.fcgi file and into the webroot/cgi-bin. If I got to the echo.fcgi url, it works great. I created a simple c file that prints hello world. I compile it using gcc -Wall -o main -lfcgi main.c What do I do with it now? Does it require something like a perl script or php script to be executed. Or, should I just be able to put it in the webroot/cgi-bin folder and go to it's url?

• perl: Run remote perl script through SSH and query environment variables on remote machine

  - by kakyo

  I'm running a perl script through SSH, in the perl script I query environment variables using $ENV{MY_VAR_NAME} and it works fine when run locally. But through SSH, all environment variables become unset. I also tried to run system("source ~/.bash_profile"); at the beginning of my script to no avail. Any tips? EDIT: Rephrasing my question. I have machine A and B. I ran my perl on machine B, trying to get the environment variables on B and it worked. Then I ssh from A to B running the same script, i.e., using this code ssh user@B perl myscript.pl This time the environment variables on B are all blank. Any tips? UPDATE: I found that running the above script, ~/.bashrc on Machine B was invoked, but after setting environment variables in ~/.bashrc, run the above command again and still I don't see any environment variables. Also, if my perl script contains only echo $ENV{PATH} Then I get /usr/bin:/bin:/usr/sbin:/sbin

• bjam wih visual studio 2010

  - by ra170

  ok, so I ran into problems with Boost under visual studio 2010, so I decided to rebuild it with bjam: such as: bjam --toolset=msvc-10.0 --build-type=complete After running bjam (successfully?) it created a new directory under boost_1_42_0 called: bin.v2 Inside bin.v2 is directory called: libs. Two issues: 1. there's lot less libs under that new directory (about 13), the old directory libs has 88. Is it supposed to be like that or did something fail? 2. the structure is somewhat different too. What do I do with this exactly? Meaning, do I copy it over to the original libs, delete the old libs, try rebulding it with different flags?

• PATH and CLASSPATH in Windows7 7 / Eclipse

  - by Richard Knop

  So I would like to set PATH and CLASSPATH system variables so I can use javac and java commands in the command line. I can just compile and run java programs in eclipse but I would also like to be able to run them through command line. This is where I have Java installed: C:\Program Files (x86)\Java jdk1.6.0_20 jre6 And this is where eclipse stores my Java projects: D:\java-projects HelloWorld bin HelloWorld.class src HelloWorld.java I have set up the PATH and CLASSPATH variables like this: PATH: C:\Program Files (x86)\Java\jdk1.6.0_20\bin CLASSPATH: D:\java-projects But it doesn't work. When I write: java HelloWorld Or: java HelloWorld.class I get error like this: Exception in thread “main” java.lang.NoClassDefFoundError: HelloWorld The error is longer, that's just the first line. How can I fix this? I'm mainly interested to be able to run compiled .class programs from the command line, I can do compiling in the eclipse.

• How to stop java application using a shell script

  - by Fernando Moyano

  I have a shell script, which is run under a opensuse linux, that starts a java application (under a jar), the script is: #!/bin/sh #export JAVA_HOME=/usr/local/java #PATH=/usr/local/java/bin:${PATH} #---------------------------------# # dynamically build the classpath # #---------------------------------# THE_CLASSPATH= for i in `ls ./lib/*.jar` do THE_CLASSPATH=${THE_CLASSPATH}:${i} done #---------------------------# # run the application # #---------------------------# java -server -Xms512M -Xmx1G -cp ".:${THE_CLASSPATH}" com.package.MyApp > myApp.out 2>&0 & This script is working fine. Now, what I want, is to write a script to kill gracefully this app, something that allows me to kill it with the -15 argument from Linux kill command. The problem, is that there will be many java applications running on this server, so I need to specifically kill this one. Any help? Thanks in advance, Fernando

• How do I ignore the Perl shebang on Windows with Apache 2?

  - by nbolton

  I have set up a local Perl web environment on my Windows machine. The application I'm working on is originally from a Linux server, and so the shebang for source .pl files look like so: #!/usr/bin/perl This causes the following error on my Windows dev machine: (OS 2)The system cannot find the file specified. Is it possible to change my Apache 2 conf so that the shebang is ignored on my Windows machine? Of course I could set the shebang to #!c:\perl\bin\perl.exe, that much is obvious; but the problem comes to deploying the updated files. Clearly it would be very inconvenient to change this back on each deploy. I am using ActivePerl on Windows 7. Update: I should have mentioned that I need to keep the shebang so that the scripts will work on our shared hosting Linux production server. If I did not have this constraint and I didn't have to use the shebang, the obvious answer would be to just not use it.

• Are there commercially deployed and used .NET CAS (Code Access Security) based applications?

  - by Dinis Cruz

  I've seen a couple threads here on SO that ask about what CAS is and how to use it.My specific is specifically focused on real-world usages of CAS. For example: DotNetNuke did some efforts in the past to be able to run under Medium Trust: is that still true? what is the % of DNN that run in partial trust (i.e. not full trust)? what & of DNN modules run in partial trust?) Sharepoint defaults to a Partially-Trusted environment on dlls executed from the bin folder: How many 'commercially' available WebParts can run in this bin folder (without changing the policy)? The key here is to be able to point to CAS success stories, so that other companies feel that they should also invest in writing CAS-enabled apps

• dynamic array pointer to binary file

  - by Yijinsei

  Hi guys, Know this might be rather basic, but I been trying to figure out how to one after create a dynamic array such as double* data = new double[size]; be used as a source of data to be kept in to a binary file such as ofstream fs("data.bin",ios:binary"); fs.write(reinterpret_cast<const char *> (data),size*sizeof(double)); When I finish writing, I attempt to read the file through double* data = new double[size]; ifstream fs("data.bin",ios:binary"); fs.read(reinterpret_cast<char*> (data),size*sizeof(double)); However I seem to encounter a run time error when reading the data. Do you guys have any advice how i should attempt to write a dynamic array using pointers passed from other methods to be stored in binary files?

• How to get bash to insert ' in the output

  - by ~danieljamesthomas

  Hi everybody, I'm rather new to bash, and somehow just haven't found out what I'm doing wrong here: (this is a small bash script calling my generator) if [ -n $folder ]; then $zorbalocation -q $generator -f -e files=\"$lFiles\" -e folder=\"lFolder\" else $zorbalocation -q $generator -f -e files=\"$lFiles\" -e folder=\".\" fi Now, obviously I want bash to execute these commands, depending on the content of folder. But, for some reason, bash insists on putting apostrophes ( ' ) around files=... and folder =... So, it tries to execute ../../../zorba/build/bin/zorba -q generator.xq -f -e 'files="test.xqlib"' -e 'folder="."' instead of ../../../zorba/build/bin/zorba -q generator.xq -f -e files="test.xqlib" -e folder="." Does anybody know why bash insists on inserting the apostrophes there? A nice day to everyone Danny

• sql exception when transferring project from usb to c:\

  - by jello

  I'm working on a C# windows program with Visual Studio 2008. Usually, I work from school, directly on my usb drive. But when I copy the folder on my hard drive at home, an sql exception is unhandled whenever I try to write to the database. it is unhandled at the conn.Open(); line. here's the exception unhandled Database 'L:\system\project\the_project\the_project\bin\Debug\PatientMonitoringDatabase.mdf' already exists. Choose a different database name. Cannot attach the file 'C:\Documents and Settings\Administrator\My Documents\system\project\the_project\the_project\bin\Debug\PatientMonitoringDatabase.mdf' as database 'PatientMonitoringDatabase'. it's weird, because my connection string says |DataDirectory|, so it should work on any drive... here's my connection string: string connStr = "Data Source=.\\SQLEXPRESS;AttachDbFilename=|DataDirectory|\\PatientMonitoringDatabase.mdf; " + "Initial Catalog=PatientMonitoringDatabase; " + "Integrated Security=True";

• Can grep be used on a Perl variable?

  - by Structure

  Is it possible one way or another to, within a Perl script, effectively execute grep against a Perl variable? An equivalent Perl function would be equally acceptable, I just want to keep the solution as simple as possible. For example: #!/usr/bin/perl #!/bin/grep $var="foobar"; $newvar="system('grep -o "foo" $var'); sprintf $newvar; Where I expect sprintf $newvar to output foo. Would also welcome any feedback on best practice here. I am not extremely familiar with Perl.

• Rationale behind Python's preferred for syntax

  - by susmits

  What is the rationale behind the advocated use of the for i in xrange(...)-style looping constructs in Python? For simple integer looping, the difference in overheads is substantial. I conducted a simple test using two pieces of code: File idiomatic.py: #!/usr/bin/env python M = 10000 N = 10000 if __name__ == "__main__": x, y = 0, 0 for x in xrange(N): for y in xrange(M): pass File cstyle.py: #!/usr/bin/env python M = 10000 N = 10000 if __name__ == "__main__": x, y = 0, 0 while x < N: while y < M: y += 1 x += 1 Profiling results were as follows: bash-3.1$ time python cstyle.py real 0m0.109s user 0m0.015s sys 0m0.000s bash-3.1$ time python idiomatic.py real 0m4.492s user 0m0.000s sys 0m0.031s I can understand why the Pythonic version is slower -- I imagine it has a lot to do with calling xrange N times, perhaps this could be eliminated if there was a way to rewind a generator. However, with this deal of difference in execution time, why would one prefer to use the Pythonic version?

• How to I serialize a large graph of .NET object into a SQL Server BLOB without creating a large bu

  - by Ian Ringrose

  We have code like: ms = New IO.MemoryStream bin = New System.Runtime.Serialization.Formatters.Binary.BinaryFormatter bin.Serialize(ms, largeGraphOfObjects) dataToSaveToDatabase = ms.ToArray() // put dataToSaveToDatabase in a Sql server BLOB But the memory steam allocates a large buffer from the large memory heap that is giving us problems. So how can we stream the data without needing enough free memory to hold the serialized objects. I am looking for a way to get a Stream from SQL server that can then be passed to bin.Serialize() so avoiding keeping all the data in my processes memory. Likewise for reading the data back... Some more background. This is part of a complex numerical processing system that processes data in near real time looking for equipment problems etc, the serialization is done to allow a restart when there is a problem with data quality from a data feed etc. (We store the data feeds and can rerun them after the operator has edited out bad values.) Therefore we serialize the object a lot more often then we de-serialize them. The objects we are serializing include very large arrays mostly of doubles as well as a lot of small “more normal” objects. We are pushing the memory limit on a 32 bit system and make the garage collector work very hard. (Effects are being made elsewhere in the system to improve this, e.g. reusing large arrays rather then create new arrays.) Often the serialization of the state is the last straw that courses an out of memory exception; our peak memory usage is while this serialization is being done. I think we get large memory pool fragmentation when we de-serialize the object, I expect there are also other problem with large memory pool fragmentation given the size of the arrays. (This has not yet been investigated, as the person that first looked at this is a numerical processing expert, not a memory management expert.) Are customers use a mix of Sql Server 2000, 2005 and 2008 and we would rather not have different code paths for each version of Sql Server if possible. We can have many active models at a time (in different process, across many machines), each model can have many saved states. Hence the saved state is stored in a database blob rather then a file. As the spread of saving the state is important, I would rather not serialize the object to a file, and then put the file in a BLOB one block at a time. Other related questions I have asked How to Stream data from/to SQL Server BLOB fields? Is there a SqlFileStream like class that works with Sql Server 2005?
