I'm trying to setup a Python module to access my C++ library. I wrote the .cpp interface and then a setup.py like this: setup( name="otawapy", ... ext_modules = [ Extension( "otawapy", ["otawapy.cpp"], include_dirs=["/home/casse/Dev/local/include"], library_dirs=["/home/casse/Dev/local/lib "], libraries = ["otawa", "elm", "gel++", "gel"] ) ] ) Notice that all paths are exacts. When I run the installation (python3 setup.py install --user on Linux), I get (I translated some messages from french): ... x86_64-linux-gnu-g++ -shared -Wl,-O1 -Wl,-Bsymbolic-functions -Wl,-Bsymbolic-functions -g -fwrapv -O2 -Wl,-Bsymbolic-functions -g -fwrapv -O2 -g -fstack-protector-strong -Wformat -Werror=format-security -Wdate-time -D_FORTIFY_SOURCE=2 build/temp.linux-x86_64-3.10/otawapy.o -L/home/casse/Dev/local/lib -lotawa -lelm -lgel++ -lgel -o build/lib.linux-x86_64-3.10/otawapy.cpython-310-x86_64-linux-gnu.so /usr/bin/ld : cannot find -lotawa : Aucun fichier ou dossier de ce nom /usr/bin/ld : cannot find -lelm : Aucun fichier ou dossier de ce nom /usr/bin/ld : cannot find -lgel++ : Aucun fichier ou dossier de ce nom /usr/bin/ld : cannot find -lgel : Aucun fichier ou dossier de ce nom collect2: error: ld returned 1 exit status error: command '/usr/bin/x86_64-linux-gnu-g++' failed with exit code 1 Even more weird, if I copy'n'paste this command in my terminal, it works without any error. Any idea? Continue reading...
