I am building a Boost Python module (.so shared library file) which depends on another external library (STXXL)
While I can build and import the example Boost Python modules, I run into problems when STXXL is thrown into the mix. Specifically when running import fast_parts
in python
I get ImportError: ./fast_parts.so: undefined symbol: _ZN5stxxl10ran32StateE
This says to me that the STXXL library isn't being linked, but I am not sure how that could be as I am linking against it and the linker isn't giving me any errors. It's worth noting I can successfully build and run standalone programs using STXXL and as far as I know the libraries are stored in a .a archive in the lib directory shown below. I have reduced my Makefile down to a single command as follows:
g++ -I/home/zenna/Downloads/stxxl-1.3.0/include -include stxxl/bits/defines.h -I/home/zenna/local/include -I/usr/include/python2.6 -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -O3 -Wall -g -DFOO=BAR -pthread -L/home/zenna/Downloads/stxxl-1.3.0/lib/ -lstxxl -L/home/zenna/local/lib/ -lboost_python -lpython2.6 -fPIC -shared -o fast_parts.so partition.cpp
Any advice?
