    Trouble with MSVC, Mingw32 and Code::Blocks

    Hi everyone, I got myself MSVC 2003, because I wanted to try it. Now I have Mingw32 and MSVC in Codeblocks, But when I try to compile a file it says:

    Fatal Error LNK1181: cannot open input file 'mingw32.lib'

    1. WTH Is MSVC trying to get this file?
    2. It doesn't exist. What can I do?
    3. I tried to link against 'libmingw32.a'. But It won't help either.

    Please, can anybody help me?

    Probably Code::Blocks doing something wrong, I expect - or perhaps you've been messing with the configuration of the project yourself.

    Do you specify under project build options that you want to link with that library? Don't if you are building with VC++...
    I might be wrong.

    Thank you, anon. You sure know how to recognize different types of trees from quite a long way away.

    Which library? SDL? Mingw32?

    mingw32 is not supposed to be linked with MS compiler code. It is a compiler specific library for gcc-mingw.

    State what exactly you did to install and configure the tools in question.
    C + C++ Compiler: MinGW port of GCC
    Version Control System: Bazaar

    Well, I linked MSVC with the MSVC version of SDL: SDLmain.lib and SDL.lib. It searches in:
    SDL\lib and Python\lib. What's wrong?

    PS: Im trying to solve it, because there is a libmscvrt.a in the mingw directory. But It ISN'T Linked with it!

    PPS: with GCC it says
    /W3: No such file or directory
    /Zi : as above
    /D_DEBUG: the same again.

    These should be VC++ specific compiler flags which GCC doesn't understand.

    Basically, you probably shouldn't switch the compiler while compiling the same project if you don't want to edit the project settings every time.

    And probably the first thing to do with a new compiler is to see whether you get a simple hello world to compile.

    Code:
    #include <stdio.h>
    int main(void)
    {
        puts("Hello world");
        return 0;
    }
    Then you can work on from there.
    I might be wrong.

    Well, I had to format my computer, and now hello world works with MSVC. I'm going to test it with GCC now. It always says:
    ...\ld.exe: crtbegin.o: No such file or directory.

    I know that's the 1000x time, but I already tried it about 20 times.

    EDIT 2: It works now, I just mixed some versions of Mingw together and it didn't go well

    Help me, please! I'm gonna get crazy! I installed Platform and .Net SDK, but now it says

    ...

    PS:
    I linked it with a downloaded msvcprt.lib and the original (Platform SDK) mscrt.lib.
    But now it says: fatal error LNK1561: entry point must be defined

    Hi Brafil,

    I don't know if this will help you but I was experiencing a similar error with CodeLite using wxWidgets.

    To solve the problem, I added the path to the lib files to the Library Path of the "Linker". Remember that the compiler settings and linker setting are for two separate programs.

    So, for linker issues like this:
    Fatal Error LNK1181: cannot open input file 'mingw32.lib'

    You need to change the linker settings for that Project.

    Hope this helps
