Fixing of-fem-fenics build

The first failure in the restructured octave forge packages is fem-fenics, with: In member function ‘virtual octave_value uBLAS_factory::matrix(const dolfin::Matrix&) const’: error: ‘const class dolfin::Matrix’ has no member named ‘data’
aa = ();
make: *** [uBLAS_factory.o] Error 1

There is some discussion about this error, and some of the issues around it, which although it makes some sense seems like it hasn’t actually been fixed in the code. The fix appears to be removing the uBLAS backend, but that seems like a chunk of work that will come along sometime. In the meantime I just need the build to complete, so I have added a patch:
sed 's/ ..;/NULL; return retval;/' >
which replaces the unfound value with NULL and returns without attempting to use it. This is not ideal but should be enough to get the build to move on.
Next the build was missing the dolfin package during the install stage, adding the correct PKG_CONFIG_PATH resolves this.
Then libQtCore was not found, adding /usr/local/Trolltech/Qt-4.8.6/lib/ to the LD_LIBRARY_PATH resolves this.
Now I am seeing

/fem-fenics-0.0.4/x86_64-unknown-linux-gnu-api-v50+/Function.oct: undefined symbol: _ZNK5boost3mpi12communicatorcvP19ompi_communicator_tEv
error: called from ‘doc_cache_create>create_cache’ in file /usr/share/tomcat7/.jenkins/workspace/octave/scripts/help/doc_cache_create.m near line 106, column 18

More work needed – this looks like it might be “boost::mpi::communicator::operator ompi_communicator_t*() const” missing from my boost_mpi library.
