I've just tried to install FEniCS on Ubuntu 16.04 and when I try to run the first example code using python3.5 I get the following 2 errors:

 RuntimeError: Expecting a string or list of strings, not
 {'slepc_real', 'sz', 'mpi', 'mpi_cxx', 'hdf5', 'boost_timer', 'm',
 'boost_filesystem', 'z', 'dolfin', 'petsc_real', 'dl'}.

 RuntimeError: Unable to compile C++ code with dijitso

image of error attached

Has anyone encountered this and managed to fix it?

the problem, in this case, is an old version of pkgconfig. Please update it with the command

$ pip3 install -U pkgconfig

Then, this problem should disappear even without your changes in /usr/lib/python3/dist-packages/dolfin/jit/jit.py

I ran into the same problem just now. I ran the ran tutorial with the python debugger:

$ python3 -m pdb ft01_poisson.py

I found the problem and fixed it (hackishly) by adding the explicit cast to list with the added list(...) statement on three lines /usr/lib/python3/dist-packages/dolfin/jit/jit.py

# Set compiler/build options 
params = dijitso.params.default_params() 
params['build']['include_dirs'] = list(dolfin_pc["include_dirs"]) 
params['build']['libs'] = list(dolfin_pc["libraries"]) 
params['build']['lib_dirs'] = list(dolfin_pc["library_dirs"])
