  • Jruby Gems-in-a-jar issue

    - by antonio
    Hi all, I am trying to write some code in ruby (using jruby) to be compiled to java bytecode with jrubyc and deployed to a remote machine where it will be run on the JVM (no ruby available there). Everything works fine as long as I am happy to stick with the standard jruby library. As explained on the jruby website, I simply copy the jruby-complete.jar library to the remote machine and include it in the classpath at runtime. I fire my compiled script and it works: cool! The problems start when I need some other libraries (typically rubygems) to run my script. I am aware of cool stuff like rawr, -which I successfully tested- to put together all you need in a single package. However that is not the solution I am looking for: I will have many small scripts to run independently and I don't want each of them to grow to at least 10 MB just because I insanely include the jruby-complete.jar in each of them. What I would like is to compile a .jar for each of the libraries that I will need to use, put all of them in a common folder on the remote machine and include them at runtime in the classpath when I run my compiled jruby scripts on the JVM. This said, I tried to follow the instructions here: http://blog.nicksieger.com/articles/2009/01/10/jruby-1-1-6-gems-in-a-jar I tried exactly the example shown there, with the "chronic" gem. Going step by step: Install the gem locally: java -jar jruby-complete-1.1.6.jar -S gem install -i ./chronic chronic --no-rdoc --no-ri Package it into a jar: jar cf chronic.jar -C chronic . Write a two lines test script, saving it as testt.rb: require 'chronic' Chronic.parse('tomorrow') Compile with: jrubyc testt.rb Run the resulting java class testt.class with the following (having both jruby-complete.jar and chronic.jar in the same folder as the java class): java -cp .:/jruby-complete.jar:./chronic.jar testt I get the following error: Exception in thread "main" file:/Users/ave2/NetBeansProjects/jrubywatir/lib/jruby-complete.jar!/METAINF/jruby.home/lib/ruby/site_ruby/shared/builtin/core_ext/symbol.rb:1:in `const_missing': uninitialized constant Chronic (NameError) from testt.rb:2 ...internal jruby stack elided... from Module.const_missing(testt.rb:2) from (unknown).(unknown)(:1) I really don't understand what I am doing wrong, and I am totally stuck on this. I am a noob in Ruby, much more used to Python: don't miss a chance to convert an infidel! :-) Thanks.

  • Web Site in solution where "Rebuild Solution" compile succeeds cannot launch debugger

    - by fordareh
    I have a solution that includes a Web Site (created using the web site template not the web app project template - converting isn't an option, btw). When I rebuild all, the compile succeeds, but strangely displays 3 errors, all of which are "Could not get dependencies for project reference 'PROJNAME'". When I try to launch the debugger, I get the "There were build errors." dialogue. Two questions: If I choose the 'Yes' option in the debug error dialogue to run the last successful build, will it run on the code that my Rebuild All just compiled? How do I resolve this issue? I checked this post and am disheartened by my prospects. What is strange, though, is that I added these same projects to a separate web site solution that compiled/debugged fine, removed the test web site and re-added the target website I would like to debug, and it failed in the same manner. Is there a secret web site .proj file for .NET web sites? http://stackoverflow.com/questions/863379/could-not-get-dependencies-for-project-reference

  • How to compile all source files (default make target does not compile all of them)

    - by Piotr Krukowiecki
    Hi, when I compile android (http://source.android.com/download) it does not compile some source files. For example there is external/bluetooth/bluez/sbc/sbc.c which is not compiled. There are also other such files. It's possible those files need not to be compiled. Or it might be that I need some special configuration to compile them. Either way, if it is possible, I'd like to compile them. Is there some way to do it? Maybe some "compile_all" make target? (I believe the reason why I want to compile all source files is not important)

  • Django ImageField validation & PIL

    - by Zayatzz
    Hello On sunday, I had problems with python modules, when I installed stackless python. Now I have compiled and installed : setuptools & python-mysqldb and i got my django project up and running again. (i also reinstalled django-1.1), Then I compiled and installed, jpeg, freetype2 and PIL. I also started using mod_wsgi instead of mod_python. But when uploading imagefield in form I get validationerror: Upload a valid image. The file you uploaded was either not an image or a corrupted image. Searchmonkey shows that it comes from field.py imagefield validation. before raising this error it imports Image from PIL, opens file and verfies it. I tried importing PIL from python prompt manually - it worked just fine. Same with Image.open and Image.verify. So what could be causing this problem? Alan

  • How to create a web framework in C# without ASPX?

    - by Mark
    I've managed to get a C# asp page running under ubuntu/apache/mono, but I don't want to write my framework in these ASP pages, I want to use straight C# and then I'll use a templating language for my views. But I don't know where to begin? C# is a compiled language, so... how would I do this? Would I compile everything and then have apache hook into the (single) executable and pass in the the request URL? Could I request specific .cs pages and then have apache tell it to compile and then "display" it only if it's been updated? Can the "view" files be compiled individually to avoid having to recompile everything every time there's a change? Is there some "base" I can work from, or am I going to have to reinvent accessing GET and POST variables (by reading header info) and all sorts of other stuff we take for granted in languages like PHP?

  • Regex slow on Windows Server 2008

    - by pjmyburg
    Hi I have a situation where my regular expressions compile extremely slowly on Windows Server 2008. I wrote a small console application to highlight this issue. The app generates its own input and builds up a Regex from words in an XML file. I built a release version of this app and ran it both on my personal laptop (running XP) and the Windows 2008 server. The regular expression took 0.21 seconds to compile on my laptop, but 23 seconds to compile on the server. Any ideas what could be causing this? The problem is only on first use of the Regex (when it is first compiled - thereafter it is fine) I have also found another problem - when using \s+ in the regular expression on the same Windows 2008 server, the memory balloons (uses 4GB+) and the compilation of the Regex never finishes. Is there a known issue with Regex and 64 bit .net? Is there a fix/patch available for this? I cannot really find any info on the net, but I have found a few articles about this same issues in Framework 2.0 - surely this has been fixed by now? More info: The server is running the 64 bit version of the .net framework (3.5 SP1) and on my laptop I have Visual Studio 2008 and the 3.5 framework installed. The regular expression is of the following pattern: ^word$|^word$|^word$ and is constructed with the following flags: RegexOptions.IgnoreCase | RegexOptions.Compiled Edit: Here is a code snippet: StringBuilder regexString = new StringBuilder(); if (!String.IsNullOrEmpty(fileLocation)) { XmlTextReader textReader = new XmlTextReader(fileLocation); textReader.Read(); while (textReader.Read()) { textReader.MoveToElement(); if (textReader.Name == "word") { regexString.Append("^" + textReader.GetAttribute(0) + "$|"); } } ProfanityFilter = new Regex(regexString.ToString(0, regexString.Length - 1), RegexOptions.IgnoreCase | RegexOptions.Compiled); } DateTime time = DateTime.Now; Console.WriteLine("\nIsProfane:\n" + ProfanityFilter.IsMatch("test")); Console.WriteLine("\nTime: " + (DateTime.Now - time).TotalSeconds); Console.ReadKey(); This results in a time of 0.21 seconds on my laptop and 23 seconds on the 2008 server. The XML file consists of 168 words in the following format: <word text="test" />

  • How to outperform this regex replacement?

    - by spender
    After considerable measurement, I have identified a hotspot in one of our windows services that I'd like to optimize. We are processing strings that may have multiple consecutive spaces in it, and we'd like to reduce to only single spaces. We use a static compiled regex for this task: private static readonly Regex regex_select_all_multiple_whitespace_chars = new Regex(@"\s+",RegexOptions.Compiled); and then use it as follows: var cleanString= regex_select_all_multiple_whitespace_chars.Replace(dirtyString.Trim(), " "); This line is being invoked several million times, and is proving to be fairly intensive. I've tried to write something better, but I'm stumped. Given the fairly modest processing requirements of the regex, surely there's something faster. Could unsafe processing with pointers speed things further?

  • iPad application submission with iPhone SDK beta 5 rejected

    - by FredM
    I try to send an specific iPad Application to iTunes connect before March 27 and as Apple says: "Only iPad apps compiled with iPhone SDK 3.2 beta 5 will be accepted for this initial review." So I compiled my application with iPhone SDK 3.2 beta 5 with a distribution provisioning profile. But when I upload my application on iTunes Connect, I have the following error: "The binary you uploaded was invalid. A pre-release beta version of the SDK was used to build the application" For sure, it's the beta 5 ! Have you got an idea? Thank you in advance. Fred

  • Shared Source CLI 4.0?

    - by Paul Alexander
    Microsoft released the Shared Source Common Language Infrastructure (the code previously known as ROTOR) code some years ago basically as a reference implementation of the .NET runtime. While the actual .NET runtime (mscorlib, mscoree, mscorjit, etc.) aren't compiled from the code, debugging them shows that they are remarkably similar and at a minimum share much of the same memory structures. This has been an invaluable resource when debugging tricky system behavior with .NET 2.0 compiled assemblies. Now that 4.0 has been released with major changes to the runtime I'd love to find the reference source for that as well. Microsoft has changed names for the source in the past so I'm either searching for the wrong thing, or it hasn't been released. Is there reference source for a .NET 4.0 compatible runtime?

  • GWT Post build command in Eclipse

    - by Henrik
    I am starting getting used to Eclipse, but I have much more experience with Visual Studio. In Visual Studio it is possible to run auto commands after the build has finished. Now I am creating a GWT project and several other projects at once in one solution (or workspace) in Eclipse. Some files which are compiled with the GWT project needs to be copied to another location when they have been compiled. I am currently doing this manually and would like to do it automatically. I am not doing it often, since the project works fine in debug mode (...?gwt.codesvr=localhost:9997). But where is the location for executing a post build command for a GWT project in eclipse? Is it possible?

  • How do I compile boost using __cdecl calling convention?

    - by Sorin Sbarnea
    I have a project compiled using __cdecl calling convention (msvc2010) and I compiled boost using the same compiler using the default settings. The project linked with boost but I at runtime I got an assert message like this: File: ...\boost\boost\program_options\detail\parsers.hpp Line: 79 Run-Time Check Failure #0 - The value of ESP was not properly saved across a function call. This is usually a result of calling a function declared with one calling convention with a function pointer declared with a different calling convention. There are the following questions: what calling convention does boost build with by default on Windows (msvc2010) how to I compile boost with __cdecl calling convention why boost wasn't able to prevent linking with code with different calling conventions? I understood that boost has really smart library auto-inclusion code.

  • Compile 32bit mercurial on x86_64

    - by krashalot
    I'm using the academic version of EPD (Enthought Python Distribution) which is 32bit. My computer is Linux x86_64. platform.architecture() returns ('32bit','ELF') I want to install Mercurial. The instructions in README didn't work at first, because make gave this error: "LONG_BIT definition appears wrong for platform (bad gcc/glibc config?)." I commented out that line in pyport.h and then it compiled fine. Now, after successful compilation I get this error when running it: ImportError: /scratch/epd/lib/python2.6/site-packages/mercurial/osutil.so: wrong ELF class: ELFCLASS64 It appears that I compiled a 64bit version of hg, and it won't run with my 32bit python. I don't see any arch flags in the mercurial makefile. How can I force it to compile in 32bit mode?

  • Why does Google's Closure Compiler leave a few unnecessary spaces or line breaks?

    - by Bungle
    I've noticed that every time I use Google's Closure Compiler Service, it leaves a few unnecessary spaces in the compiled code presented on the right-hand side of the page. These correspond to line breaks in the hosted version of the compiled code. For example (note the line breaks, each of which seems unnecessary): http://troy.onespot.com/static/stack_overflow/closure_spaces.js To date, I've just been removing them manually, but I'm curious why they're there. Is it to limit the line length of the hosted version of the code to make it more readable? Could the compiler be smart enough to leave or insert those intentionally to maximize GZIP compression efforts? I know that they have a trivial effect on the file size, but with so much effort going into minifying every last byte in the source script, it's counterintuitive why they're there.

  • silverlight for .NET / CLR based numerical computing on osx

    - by Jonathan Shore
    I'm interested in using F# for numerical work, but my platforms are not windows based. Mono still has a significant performance penalty for programs that generate a significant amount of short-lived objects (as would be typical for functional languages). Silverlight is available on OSX. I had seen some reference indicating that assemblies compiled in the usual way could not be referenced, but not clear on the details. I'm not interested in UIs, but wondering whether could use the VM bundled with silverlight effectively for execution? I would want to be able to reference a large library of numerical models I already have in java (cross-compiled via IKVM to .NET assemblies) and a new codebase written in F#. My hope would be that the silverlight VM on OSX has good performance and can reference external assemblies and native libraries. Is this doable?

  • Compiling zip component for PHP 5.2.11 in MAMP PRO

    - by Zlatoroh
    Helo I installed MAMP PRO on my Macbook Pro (10.6) some time ago. Now I would like to use zip functions in php. I found that I must add zip.so to my extension folder and edited php.ini. On my computer I have two different versions of PHP one in MAMP folder and other in user/lib which was pre-installed on my system. Now I wish to compile my zip library for MAMP version. I got zip sources for my version of PHP then in terminal called function /Applications/MAMP/bin/php5/bin/phpize so it uses mamp php version ./configure make then I moved compile zip.so to extensions/no-debug-non-zts-20060613. When MAMP is launched it returns this error: [11-Apr-2010 16:33:27] PHP Warning: PHP Startup: zip: Unable to initialize module Module compiled with module API=20090626, debug=0, thread-safety=0 PHP compiled with module API=20060613, debug=0, thread-safety=0 These options need to match in Unknown on line 0 Can some body explain to me how to do this the right way.

  • How to make php-closure compiler output to a predefined file name? (Updated)

    - by Mohammad
    Php-closure compiler (linked to source code) currently writes the compiled code to a md5 encoded filename. How can I make it so it write the compiled code to a predefined name like compiled_code.js? . . I think it has to do with the write() function on Line 164. It gets the filename via the _getCacheFileName() function (Line 272). function _getCacheFileName() { return $this->_cache_dir . $this->_getHash() . ".js"; } I've tried altering it to this: function _getCacheFileName() { //return $this->_cache_dir . $this->_getHash() . ".js"; return 'copiled_code.js'; } without any results. Thanks to all of you in advance!

  • Understanding the output of ldd

    - by nebukadnezzar
    I'm having a hard time understanding the output of ldd - Especially the processor identifiers. The string in question is this one: Shortest.so: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked, from ']', not stripped I have several questions about it: What does "ELF" mean? I know that's what Linux binaries are called like (Windows Binaries are called PE Binaries, "Portable Executable" Binaries), but isn't ELF an abbreviation for something? What does LSB mean? I can't even guess it... I see the string "Intel" there, now I seriously wonder about the portability of Linux binaries, as ldd seems to expect every binary to be compiled on a intel processor... but what if it wasn't compiled on a Intel processor? Or when I attempt to run the binary on a computer that doesn't run ontop of a Intel processor? Why the ']'? My guess is it should be some sort of Linker identify, but ']' doesn't look much like a Identifier... Thanks in advance

  • Problem wit MDAC when trying to compile in VS2008 using x64 bit target platform

    - by grobartn
    I am trying to compile an 32 bit application. I am aware of problems with it but that is why its being compiled on 64 bit version. I am hanging at this problem. Application uses lots of sql stuff. In sqltypes.h file: (provided by MDAC) #ifdef _WIN64 typedef INT64 SQLLEN; typedef UINT64 SQLULEN; typedef UINT64 SQLSETPOSIROW; #else For some reason when its compiled on 32 bit platform it works great But when I try building it on 64 it goes berserk. Error 61 error C2146: syntax error : missing ';' before identifier 'SQLLEN' ..\external\microsoft sdk\include\sqltypes.h 50 It does not recognize INT64, UINT64. Is there something I need to enable so it will work under 64 build process? Missing some #include or #define? Any help would be great Thanks

  • How does a virtual machine work?

    - by Martin
    I've been looking into how programming languages work, and some of them have a so-called virtual machines. I understand that this is some form of emulation of the programming language within another programming language, and that it works like how a compiled language would be executed, with a stack. Did I get that right? With the proviso that I did, what bamboozles me is that many non-compiled languages allow variables with "liberal" type systems. In Python for example, I can write this: x = "Hello world!" x = 2**1000 Strings and big integers are completely unrelated and occupy different amounts of space in memory, so how can this code even be represented in a stack-based environment? What exactly happens here? Is x pointed to a new place on the stack and the old string data left unreferenced? Do these languages not use a stack? If not, how do they represent variables internally?

  • Compiling OpenSSL for boost asio for Microsoft Visual Studio 2010

  • Java code to convert a list of dependencies into a build order?

    - by Egon Willighagen
    Given I have a list of dependencies, like: module1 module2 dependsOn module1 module3 dependsOn module1 module4 dependsOn module3 I would like to create a build order where each build step is found on one line, and each line contains a list of one or more modules which can be compiled at the same time, and which only depend on modules compiled earlier. So, for the above data set, create a list like: module1 module2,module3 module4 Now, this is basically just a problem of creating a directed graph, and analyzing it. Now, I am using Ant, and would very much like to use something off-the-shelf... what is the minimum of custom code I need to have it create such a dependency-aware build list starting from the given input? BTW, these modules are actually custom modules, so maven will not work.

The BSD licensed code is compiled into the same binary as my code (but none of it is changed) The Ms-PL licensed code is compiled into another assembly next to my code and linked at runtime (and none of it is changed what so ever). Can I release my software under GPLv3 and without any legal problems?

  • Is there a way to convert a swf to an .abc file?

    - by Jeremy Ruppel
    I'm looking for a way, preferably a command-line utility, to pump out an .abc file for a compiled swf. I've looked into asc.jar, but so far it seems like it can only accept classes, not compiled swfs. Anybody know of a good way to do this? The end-goal of this process is to use Zwetan's RedTamarin project to run describeType on some specific classes inside a loaded swf, but there are complications with SecurityDomain preventing me from using Loader.loadBytes. If there's another good way to describe classes in the loaded swf via command-line, I'd be interested in that solution as well. Cheers, J
