Hi Victor,
Would you mind testing something for me quickly?
We have a bit of code floating around in
./cmake/configure/configure_1_threads.cmake
that might create an issue (depending on icc and cmake version I guess).
Would you mind modifying the file as in the attached diff output? Simply
copy the patch file into the source directory of deal.II and run
$ patch -p1 < remove_pthread_workarounds.patch
If that doesn't help, then my next request would be to see the full
terminal output of the cmake invocation.
Also, it seems that cmake barfs at the final sanity check where we check
whether we can compile a simply hello world program with our final
compile configuration. You can disable this check temporarily by
applying remove_sanity_checks.patch (that removes the corresponding
check from cmake./setup_finalize.cmake). cmake should then run through
without a problem creating a file 'detailed.log'. I would like to see
this one. (You can try to compile the library from here - but either the
final link of the library or linking any program against the library
will likely fail).
Best,
Matthias
