This break started with
CMake Error at CMakeLists.txt:889 (message):
Generation of form files failed:
sh: ffc: command not found
…in build 202, but then a change was made to update the dependencies, requiring ffc version 1.7.0. However the ffc version on the master branch is still 1.6.0, a little searching around shows that the ‘next’ branch has advanced its version number to 1.7.0. Rebuilding using ‘next’ branch instead gives: “OSError: Unable to find SWIG version 3.0.3 or higher.”
Adding SWIG to the CI builds resolves this and gets dolfin building again.
Fixed in build 214.
