assuming you're on unix,

1) get sources from www.python.org
2) unpack
3) type "./configure"
4) type "make"

ta da!

Hi!

I did it.
The only file I found was 'libpython1.5.a'.
This you told me in the other mail.

Ok. Thanks!

But how can I get the other files (libModules.a, libPython.a, libParser.a,
libObjects.a) from libpython1.5.a?

Or can anybody send me these files (SUN/Solaris OS)???
All trials with make and configure were not successful.

Thanks for more hints and comments!

Use libpython1.5.a instead of the others; it replaces all four of
them to make embedding easier.

Thanks!

But there are still errors.

My programm is very little, so I think, there are no syntax errors in it:

#include "Python.h"
int main(int argc, char **argv)
{
Py_Initialize();
PyRun_SimpleString("print 'Hallo, embedded world!'");
return 1;
}

Ok. I compiled and linked my program with the command:

CC -I/path/to/include/ -L/path/to/lib/ -lpython1.5 -o gui gui.cxx

errors:
undefined symbols ... first referenced in 'my_object_file.o'

The undefined symbols Py_Initialize and PyRun_SimpleString are still the
error messages.
What did I wrong?
Can anybody send me the compiler-options for embedding needed object-files
or other flags? Has anyone written a makefile, to do these work?

Thanks a lot!

Order matters? Try:

CC -I/path/to/include/ -L/path/to/lib/ -o gui gui.cxx -lpython1.5

Good luck

I tried, but there are more undefined symbols yet. All symbols are first
referenced in libpython1.5.a(socketmodule.o)!

Who know what else can I do? Has anybody done this before?

Thanks!

Are the missing symbols socket-related (gethostbyname, etc.)? If
you're doing all this on Solaris, you need to link with "-lsocket
-lnsl" to get all the symbols.

Thanks!
Many errors are removed.

But there are two undefined symbols yet:
- importdl.o
- regexpr.o

Could you help me more, please???

Thanks a lot!
