Compiles fine for me (after changing the path to my graph.hh): gcc -fno-strict-aliasing -g -O2 -DNDEBUG -g -fwrapv -O3 -Wall -fPIC -I/home/vbraun/Sage/git-temp/local/include -I/home/vbraun/Sage/git-temp/local/include/csage -I/home/vbraun/Sage/git-temp/src -I/home/vbraun/Sage/git-temp/src/sage/ext -I/home/vbraun/Sage/git-temp/local/include/python2.7 -c build/cythonized/sage/graphs/bliss.cpp -o build/temp.linux-x86_64-2.7/build/cythonized/sage/graphs/bliss.o -fno-strict-aliasing -w -fno-tree-dominator-opts
I can't import the resulting module because it doesn't link against bliss: sage: import sage.graphs.bliss --------------------------------------------------------------------------- ImportError Traceback (most recent call last) <ipython-input-1-75682df38474> in <module>() ----> 1 import sage.graphs.bliss ImportError: /home/vbraun/Sage/git-temp/local/lib/python2.7/site-packages/sage/graphs/bliss.so: undefined symbol: _ZN5bliss5GraphC1Ej But compilation is fine. You either aren't using the "gcc" that you think you are using, or maybe have a clashing header somewhere.
