    EXTREMELY Weird problem...

    Okay so could someone please tell me what the **** IS GOING ON... Basically, I've made a SSH client in C++ using libssh2. The problem is, it only runs on machines with Visual C++ Express Edition installed... I'm not sure if other versions (such as Visual Studio) or earlier versions (such as 2005) would get it working or not.

    I tried to get it working by installing the Visual C++ Redistributable library but that doesn't fix the problem... No matter which version of the redistributable library I install, the program won't run, unless I install Visual C++. I tried installing redistributable 2008, 2008 SP1, 2005, and so fourth.

    The program is compiled in 2008...

    So how is this possible? What is going on? This is extremely frustrating... Okay thank you lol.

    Make sure that you did a release build of your application (as opposed to a debug build).

    Yep, definitely release build.

    Then use dependency walker to see what's not being found.

    That I did, all the DLLs were there after I installed the redistributable library but it still wouldn't run...

    Code::Blocks is a free IDE that will use the VC++ compiler, trying compiling through that. If that doesn't work, download MinGW GCC (also will run in Code::Blocks) and try compiling the program with it - you'll have to make a couple changes, but it shouldn't be a problem so long as your program isn't doing some special exception handling.

    It doesn't even compile in CodeBlocks... I get all these unresolved external symbol errors. I get the exact same errors if I compile the project in VC++ with /MT instead of /MD... Could this be the cause of the problem (I'm using /MD instead of /MT because /MT doesn't work)?

    That doesn't answer the question of why it isn't working. I don't like the debugging approach of "start changing stuff until it works." It's important to understand what's going on.

    What exactly happens when you try to run the program and it fails? Does it fail silently, pop some kind of dialog, what?
    Code:
    //try
    //{
    	if (a) do { f( b); } while(1);
    	else   do { f(!b); } while(1);
    //}

    Well, if I run it on XP and it fails it says something along the lines of "This program failed to run", and I get a different error message on 7 and Vista... I'll re-install XP on a virtual machine again and tell you exactly what it says, although the output wasn't very revealing lol, it was just something simple to let me know something is messed up.

    Ok on XP Pro it says "The system cannot execute the specified program." (prints it to stdout in the command prompt).

    Yes I have bithub: Visual C++ files can be redistributed using either the provided Redistributable Merge Modules, or the Visual C++ Redistributable Package, I tried that In fact, I just reformatted the test machine, tried to run it, got that error. I then installed the Visual C++ 2008 Redistributable Package, ran dependency walker, and it says the following DLL's are missing still:

    MSVCP90.DLL
    MSVCR90.DLL
    IESHIMS.DLL
    WER.DLL

    I tried the 2008 version and the 2008 Service Pack 1 version. I don't quite understand how this may be possible as it was my understand that the intention of the redistributable package was to register those exact DLLs on my system?!

    Edit: I just tried both methods at:

    http://msdn.microsoft.com/en-us/libr...91(VS.80).aspx

    Neither worked...

    Okay uh I just read this in the Event Viewer under System...

    Resolve Partial Assembly failed for Microsoft.VC90.DebugCRT. Reference error message: The referenced assembly is not installed on your system.

    Now this leads me to believe that even know I have it on release mode it's compiling in debug mode or something? And since I'm supplying the non Debug CRT files, this is why it will not run? Why would it be looking for DebugCRT... I'm compiling in Release.

    Under project properties->Configurations Properties->C++->Code Generation-> Runtime Library set it to Multithreaded or Debug Multithreaded. Do not use the DLL version of the runtime unless your customer has the runtime installed, which 99.99% don't.
    Until you can build a working general purpose reprogrammable computer out of basic components from radio shack, you are not fit to call yourself a programmer in my presence. This is cwhizard, signing off.

    He said that he couldn't do that (although I'm not sure of the cause).
