Hello all,
I would like to use an existing C-Function from python. Therfore I made up an wrapper (wrap.c), where all the variable transformations from Python to C are done. That works. Now I would like to call the external fuction, which is placed in lets say ext_foo.a with a corresponding ext_foo.h and can be used as a library from plain C.
I am assuming, that I do have to include the ext_foo.h in my wrap.c with #include "ext_foo.h"
that I have to introduce the function in my C-Code:
extern int foo(int);
that I have to tell the setup.py using the distutils stuff where the library can be found...
when compiling a C-Code which is not for python usage I do type
gcc -o test.o ./test.c ./ext_foo.a -I./foo_h_file_path/
and everything is fine, where within these setup.py files do I have to mention the ./ext_foo.a ? When I do place it in the sources-tag, setup procedure complains that it doesn't know any .a files... if I don't mention it explicitly, just giving the include_dirs, compilation works fine, but when importing from python 'import wrap' I do get the message: Symbol not found: _foo
Any help is very much appreciated! Thanks Philipp
