    Trouble including Python.h

    Hi, everyone.

    This is on WinXP SP2, with Python 2.4.3 and DJGPP gcc 4.1.0.

    I'm having trouble including Python.h in a C file. The following C
    code:

    #include "Python.h"

    int main()
    {
    return 0;
    }

    when compiled with "gcc -I..\Python2.4\i nclude\", gives more than 1000
    lines of errors, beginning with:

    c:/documents and settings/marcelo.gosling/my
    documents/djgpp/bin/as.exe: BFD 2.16.1 assertion fail
    .../../bfd/coff-i386.c:576
    c:/documents and settings/marcelo.gosling/my
    documents/djgpp/tmp/ccACtxBR.s: Assembler messages:

    token
    .../../Python2.4/include/object.h:130: error: expected ')' before '*'
    token

    Am I missing something important here?

    Thanks in advance,

    Marcelo

      Try

      #undef _DEBUG
      #include "C:\Python24\in clude\python.h"

      or which ever path your python.h is located at

      works for me

          No, that didn't do the trick. The main reason I'm posting this here is
          that I get all tese error messages just from including Python.h, the
          code itself does absolutely nothing.

          Cheers

              Hmmmm.... the *assembler* appears to be grumbling about its input. I'd
              suspect that you have a mangled DJGPP installation. You may be better
              asking on the DJGPP mailing list.

              Aside: Wouldn't it have been better to install DJGPP in c:\djgpp????

              1. You allegedly have a 6-line test program. What is this example_wrap.c
              that has 112 lines (or more) in it?
              2. What was the full compiler command line?
              3. What are you doing with DJGPP? Are you attempting to make an MS-DOS
              port of Python?
              4. Have you successfully compiled linked and executed anything with this
              installation of DJGPP? Does the standard "Hello, world!" program work?
              5. Have you tried compiling (not linking) this:

              #include "Python.h"
              void dummy() {}

              HTH,
              John

                  If you're trying to use SWIG (which could quite plausibly have created
                  an example_wrap.c from an example.c), wouldn't you be better off with
                  MinGW??????

                  I suggest you back away from your 1000-error-message train smash and try
                  telling us what you are trying to accomplish and a little bit more of
                  the history of how you got on this path.

                  Cheers,
                  John

                      __declspec is a Microsoft extension. Are you trying to build the Visual
                      C++ source with gcc?
