Trouble including Python.h

[Marcelo Gosling]

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\include\", 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

Am I missing something important here?

Thanks in advance,

Try

#undef _DEBUG
#include "C:\Python24\include\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.

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

1. You allegedly have a 6-line test program. What is this example_wrap.c
that has 112 lines (or more) in it?

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?
