Dear @dparsons ,
I tried to remove all the files related to FEniCS in the usr/local folder but, unfortunately, the problem persists.
At least, in the error message now the folder changed from usr/local/include/dolfin/ to /usr/include/dolfin :
------------------- Start compiler output ------------------------
In file included from /tmp/tmpatp8ubfw/dolfin_expression_e8cadffda6c83113f8e006b97f0c13b5.cpp:13:
/usr/include/dolfin/function/Expression.h:25:10: fatal error: ufc.h: No such file or directory
25 | #include <ufc.h>
| ^~~~~~~
compilation terminated.
------------------- End compiler output ------------------------
Do you have maybe another idea?
