Category: Installation/Building Group: 2.3.x Status: Open Resolution: None Priority: 5 Private: No Submitted By: Christoph Willing (cwilling) Assigned to: Nobody/Anonymous (nobody) Summary: out of tree build failure with python Initial Comment: Building with -DPYTHON_BINDINGS=ON fails during an out of tree build. It succeeds with "in tree" build. Out of tree build fails at linking stage with: g++ -pthread -shared -I/usr/include/eigen2 build/temp.linux-x86_64-2.7/tmp/SBo/openbabel-2.3.1/scripts/python/openbabel-python.o -L/tmp/SBo/openbabel-2.3.1/scripts/python/../../lib -L/tmp/SBo/openbabel-2.3.1/scripts/python/../../lib64 -L../lib -L/usr/lib64 -lopenbabel -lpython2.7 -o /tmp/SBo/openbabel-2.3.1/build/scripts/pybuild/_openbabel.so /usr/lib64/gcc/x86_64-slackware-linux/4.7.1/../../../../x86_64-slackware-linux/bin/ld: cannot find -lopenbabel Firstly, in the line that fails, none of the directory paths specified to look for libopenbabel contain the "build" directory (the root of my out of tree build), therefore linking with -lopenbabel could never succeed. Secondly, Some of these directory paths specify "scripts/python" but no "scripts/python" directory has been generated by cmake in the build directory (only the scripts directory). Thirdly, the path for python-openbabel.o is wrong (also incorrect path): build/temp.linux-x86_64-2.7/tmp/SBo/openbabel-2.3.1/scripts/python/openbabel-python.o should be: scripts/build/temp.linux-x86_64-2.7/tmp/SBo/openbabel-2.3.1/scripts/python/openbabel-python.o I can "fix" these things by creating the python directory and then running the same command at command line but including the correct library path i.e. (from the out of tree "build" directory) mkdir -p scripts/python g++ -pthread -shared -I/usr/include/eigen2 scripts/build/temp.linux-x86_64-2.7/tmp/SBo/openbabel-2.3.1/scripts/python/openbabel-python.o -L/tmp/SBo/openbabel-2.3.1/scripts/python/../../lib -L/tmp/SBo/openbabel-2.3.1/build/scripts/python/../../lib64 -L../lib -L/usr/lib64 -lopenbabel -lpython2.7 -o /tmp/SBo/openbabel-2.3.1/build/scripts/pybuild/_openbabel.so which succeeds in building _openbabel.so Conclusion: cmake isn't generating correct directories and linker paths for out of tree build with python Platform - Linux, cmake-2.8.8, openbabel-2.3.1 ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=428740&aid=3577236&group_id=40728 ------------------------------------------------------------------------------ Don't let slow site performance ruin your business.
