POHow to link C lib against python for embedding under Windows?
text
Body
copied!<p>I am working on an application written in C. One part of the application should embed python and there is my current problem. I try to link my source to the Python library but it does not work.</p> <p>As I use MinGW I have created the python26.a file from python26.lib with dlltool and put the *.a file in <code>C:/Program Files (x86)/python/2.6/libs</code>.</p> <p>Therefore, I compile the file with this command:</p> <pre><code>gcc -shared -o mod_python.dll mod_python.o "-LC:\Program Files (x86)\python\2.6\libs" -lpython26 -Wl,--out-implib,libmod_python.a -Wl,--output-def,mod_python.def </code></pre> <p>and I get those errors:</p> <pre><code>Creating library file: libmod_python.a mod_python.o: In function `module_init': mod_python.c:34: undefined reference to `__imp__Py_Initialize' mod_python.c:35: undefined reference to `__imp__PyEval_InitThreads' ... and so on ... </code></pre> <ul> <li>My Python "root" folder is <code>C:\Program Files (x86)\python\2.6</code></li> <li>The Devsystem is a Windows Server 2008</li> <li>GCC Information: <code>Reading specs from C:/Program Files (x86)/MinGW/bin/../lib/gcc/mingw32/3.4.5/specs Configured with: ../gcc-3.4.5-20060117-3/configure --with-gcc --with-gnu-ld --with-gnu-as --host=mingw32 --target=mingw32 --prefix=/mingw --enable-threads --disable-nls --enable-languages=c,c++,f77,ada,objc,java --disable-win32-registry --disable-shared --enable-sjlj-exceptions --enable-libgcj --disable-java-awt --without-x --enable-java-gc=boehm --disable-libgcj-debug --enable-interpreter --enable-hash-synchronization --enable-libstdcxx-debug Thread model: win32 gcc version 3.4.5 (mingw-vista special r3)</code></li> </ul> <p>What I do wrong? How I get it compiled and linked :-)?</p> <p>Cheers, gregor</p> <hr> <p><strong>Edit:</strong> I forgot to write information about my Python installation: It's the official python.org installation 2.6.1</p> <p>... and how I created the python.a file:</p> <pre><code>dlltool -z python.def --export-all-symbols -v c:\windows\system32\python26.dll dlltool --dllname c:\Windows\system32\python26.dll --def python.def -v --output-lib python26.a </code></pre>
