  • Problem with regular expression for some special parttern.

    - by SpawnCxy
    Hi all, I got a problem when I tried to find some characters with following code: preg_match_all('/[\w\uFF10-\uFF19\uFF21-\uFF3A\uFF41-\uFF5A]/',$str,$match); //line 5 print_r($match); And I got error as below: Warning: preg_match_all() [function.preg-match-all]: Compilation failed: PCRE does not support \L, \l, \N, \U, or \u at offset 4 in E:\mycake\app\webroot\re.php on line 5 I'm not so familiar with reg expression and have no idea about this error.How can I fix this?Thanks.

  • C++ DLL Export: Decorated/Mangled names

    - by Bob
    Created basic C++ DLL and exported names using Module Definition file (MyDLL.def). After compilation I check the exported function names using dumpbin.exe I expect to see: SomeFunction but I see this instead: SomeFunction = SomeFunction@@@23mangledstuff#@@@@ Why? The exported function appears undecorated (especially compared to not using the Module Def file), but what's up with the other stuff? If I use dumpbin.exe against a DLL from any commercial application, you get the clean: SomeFunction and nothing else......

  • Importing Python modules without installing - Sybase ASE

    - by Michael
    I need to use the Sybase Python module but our SA's won't install because it's not in the repo's. I've downloaded it and placed it on the box and would just like to 'import' or 'include' the module without installing it first. - Is this possible? From the looks of it (Sybase ASE) it needs some type of compilation before use. Is it possible for this type of work around?

  • Why does the Java compiler complain about a local variable not having been initialized here?

    - by pele
    int a = 1, b; if(a > 0) b = 1; if(a <= 0) b = 2; System.out.println(b); If I run this, I receive: Exception in thread "main" java.lang.Error: Unresolved compilation problem: The local variable b may not have been initialized at Broom.main(Broom.java:9) I know that the local variables are not initialized and is your duty to do this, but in this case, the first if doesn't initialize the variable?

  • #include headers in C/C++

    - by Carlos
    After reading several questions regarding problems with compilation (particularly C++) and noticing that in many cases the problem is a missing header #include. I couldn't help to wonder in my ignorance and ask myself (and now to you): Why are missing headers not automatically checked and added or requested to the programmer? Such feature is available for Java in Netbeans for example.

  • How to suppress warnings in external headers in Visual C++

    - by Bob Whiteman
    I'm starting a new BREW project, and I'd like to compile with Warning Level 4 (/W4) to keep the application code nice and clean. The problem is that the BREW headers themselves don't compile cleanly with /W4. In gcc you can differentiate between application and system headers by using -I and -isystem, and then by default gcc doesn't report any compilation warnings in system headers. Is there an equivalent mechanism in Visual C++?

  • Good C++ Debugging/IDE Environment for Linux?

    - by Brandon Pelfrey
    I have a friend who is trying to make the switch to Linux, but is hung up on the apparent lack of debugging/IDE environments for C++, especially as they relate to template programming. He has been using visual studio for years and is maybe a little spoiled by their awesome IDE. Does anyone have any good suggestions for an environment where he can, under Linux, develop and debug with all of the usual things (Breakpoints, line highlighting for compilation errors, step in/over/out/etc, etc) that he's accustomed to? Thanks!

  • Visual C# Express 2010: how to set language to C# 2.0

    - by luqui
    I am using Visual C# Express 2010 to develop an application for the Unity3D game engine, which only supports C# 2.0. That is, I am only using it to edit code, but the compilation is done by Unity. I'm wondering if there is a way to configure Visual C# to edit C# 2.0, so that, for example, it yells if I (out of habit) try to use a var declaration or foo => bar function. Thanks!

  • populate a list dynamically in ant build script

    - by user1164061
    I have the following directory structure: vardir1 vardir2 vardir3 vardir4 constantdir1 Inside constantdir1, i have an ant build script which takes the list of vardir1 to vardir4 and compiles them sequentially. The situation is, vardir1 to vardir4 may or may not exist all the time. Right now I have hard coded the values in the list and checking to see if the vardir is available before I kick off its compilation. Is there any way I can dynamically populate this list in my ant build script?

  • How to Integrate C++ compiler in Visual Studio 2008

    - by Kasun
    Hi Can someone help me with this issue? I currently working on my project for final year of my honors degree. And we are developing a application to evaluate programming assignments of student ( for 1st year student level) I just want to know how to integrate C++ compiler using C# code to compile C++ code. In our case we are loading a student C++ code into text area, then with a click on button we want to compile the code. And if there any compilation errors it will be displayed on text area nearby. (Interface is attached herewith.) And finally it able to execute the code if there aren't any compilation errors. And results will be displayed in console. We were able to do this with a C#(C# code will be loaded to text area intead of C++ code) code using inbuilt compiler. But still not able to do for C# code. Can anyone suggest a method to do this? It is possible to integrate external compiler to VS C# code? If possible how to achieve it? Very grateful if anyone will contributing to solve this matter? This is code for Build button which we proceed with C# code compiling CodeDomProvider codeProvider = CodeDomProvider.CreateProvider("csharp"); string Output = "Out.exe"; Button ButtonObject = (Button)sender; rtbresult.Text = ""; System.CodeDom.Compiler.CompilerParameters parameters = new CompilerParameters(); //Make sure we generate an EXE, not a DLL parameters.GenerateExecutable = true; parameters.OutputAssembly = Output; CompilerResults results = codeProvider.CompileAssemblyFromSource(parameters, rtbcode.Text); if (results.Errors.Count > 0) { rtbresult.ForeColor = Color.Red; foreach (CompilerError CompErr in results.Errors) { rtbresult.Text = rtbresult.Text + "Line number " + CompErr.Line + ", Error Number: " + CompErr.ErrorNumber + ", '" + CompErr.ErrorText + ";" + Environment.NewLine + Environment.NewLine; } } else { //Successful Compile rtbresult.ForeColor = Color.Blue; rtbresult.Text = "Success!"; //If we clicked run then launch our EXE if (ButtonObject.Text == "Run") Process.Start(Output); // Run button }

  • Passing enums to functions in C++

    - by rocknroll
    Hi all, I have a header file with all the enums listed (#ifndef #define #endif construct has been used to avoid multiple inclusion of the file) that I use in multiple cpp files in my application.One of the enums in the files is enum StatusSubsystem {ENABLED,INCORRECT_FRAME,INVALID_DATA,DISABLED}; There are functions in the application delcared as ShowStatus(const StatusSubsystem&); Earlier in the application when I made calls to the above function like ShowStatus(INCORRECT_FRAME); my application used to compile perfectly. But after some code was added The compilation halts giving the following error: File.cpp:71: error: invalid conversion from `int' to `StatusSubsystem' File.cpp:71: error: initializing argument 1 of `void Class::ShowStatus(const StatusSubsystem&) I checked the code for any conflicting enums in the new code and it looked fine. My Question is what is wrong with the function call that compiler shows as erroneous? For your reference the function definition is: void Class::ShowStatus(const StatusSubsystem& eStatus) { QPalette palette; mStatus=eStatus;//store current Communication status of system if(eStatus==DISABLED) { //select red color for label, if it is to be shown disabled palette.setColor(QPalette::Window,QColor(Qt::red)); mLabel->setText("SYSTEM"); } else if(eStatus==ENABLED) { //select green color for label,if it is to be shown enabled palette.setColor(QPalette::Window,QColor(Qt::green)); mLabel->setText("SYSTEM"); } else if(eStatus==INCORRECT_FRAME) { //select yellow color for label,to show that it is sending incorrect frames palette.setColor(QPalette::Window,QColor(Qt::yellow)); mLabel->setText("SYSTEM(I)"); } //Set the color on the Label mLabel->setPalette(palette); } A strange side effect of this situation is it compiles when I cast all the calls to ShowStatus() as ShowStatus((StatusSubsystem)INCORRECT_FRAME); Though this removes any compilation error, but a strange thing happens. Though I make call to INCORRECT_FRAME above but in function definition it matches with ENABLED. How on earth is that possible? Its like while passing INCORRECT_FRAME by reference, it magically converts to ENABLED, which should be impossible. This is driving me nuts. Can you find any flaw in what I am doing? or is it something else? The application is made using C++,Qt-4.2.1 on RHEL4. Thanks.

  • Professional way to write project documentation

    - by EugeneP
    What tools and standards do you use to describe your project, database, modules, classes, their interaction for programmers, let's say after the project is finished. Do you use UML? Are there enterprise standards for Java developers, how to write such a documentation let's say from SUN? Are there specific tools that simplify this documentation process & compilation of neccessary docs. If there are good books on project documenting process, please give me links to Amazon.

  • CUPS Server compiled for Windows?

    - by Peter Illes
    Is there a version of the CUPS server available for Windows? Looking at the CUPS source code it seems it is ready for Visual Studio compilation, but I did not find any trace of an actual supported package. I'd like to set up a CUPS server on Windows so that I can print form Linux/MacOSX/Win clients to printers I set up on this server.

  • Long time to load first sql connection in .NET

    - by Shrage Smilowitz
    For some reason it takes 7 seconds to open a connection to a sql server database for the firt time, subsequent connections takes a second. any idea what could be the reason? I'm using C# and asp.net Its after compilation, i essence every time i restart the site, which means every time it needs to actualy create the "first" connection. i understand that setting up connection pooling has overhead, but i have never seen that i should take 7 second to set it up.

  • debug=true in web.config = BAD thing?

    - by MateloT
    We're seeing lots of virtual memory fragmentation and out of memory errors and then it hits the 3GB limit. The compilation debug is set to true in the web.config but I get different answers from everyone i ask, does debug set to true cause each aspx to compile into random areas of ram thus fragmenting that ram and eventually causing out of memory problems?

  • Suppress errors of files that are not set to be built from the "Error List" window

    - by ohadsc
    I have some cs files in my project that are not set to be built (Properties - Build Action = None). They contain bits of code that don't compile as a whole and are there merely for reference. I don't care about any compilation errors in them, but they appear in the "Error List" window, cluttering it. Is there some way to tell VS to ignore errors in that file? Or in all files not set to be built, at that ? I'm using VS 2010 Thanks

  • Lightweight Java reporting engine

    - by tuler
    I'm looking for a lightweight java reporting engine to be embedded in an applet application. My first option was Jasper Reports, but the jar is over 2Mb, a little too heavy (and too bloated) for my needs. I don't know if there is modular jasper distribution, with funcionalities split in several jars (like html rendering, pdf, excel, compilation, runtime, etc). I need to preview the report using Swing and print it. PDF export is a plus.

  • Which work process in my company should I Improve first?

    - by shoren
    I've just started to work in a new place, and I see several things they do that I find really terrible, and I want to know if they are indeed so wrong, or I am just too strict. Please let me know if my criticism is in place, and your opinion on which problem is the worst and should be fixed first. The developement is all in Java. 1) Not using svnignore. This means svn stat can't be used, and developers forget to add files and break the build. 2) Generated files go to same folders as committed files. Can't use simple maven clean, have to find them one by one. Maven clean doesn't remove all of them. 3) Not fixing IDE analyze warnings. Analyze code returns about 5,000 warning, of many different kinds. 4) Not following conventions: spring beans names sometimes start with uppercase and sometimes not, ant properties sometimes with underline and sometimes with dots delimiter, etc. 5) Incremental build takes 6 minutes, even when nothing is changed. 6) Developers only use remote debug, and don't know how to run the Tomcat server internally from the IDE. 7) Developers always restart the server after every compilation, instead of dynamically reloading the class and saving the server's state. It takes them at least 10 minutes to start checking any change in the code. 8) Developers only compile from command line. When there are compilation errors, they manually open the file and go the the problematic line. 9) A complete mess in project dependencies. Over 200 open sources are depended on, and no one knows what is indeed needed and why. They do know that not all dependencies are necessary. 10) Mixing Maven and Ant in a way that disables the benefits of both. In one case, even dependency checks are not done by Maven. 11) Not using generics properly. 12) Developers don't use Subversion integration with IDE (Eclipse, Intellij Idea). What do you think? Where should I start? Is any of the things I mentioned not really a problem?
