# https://github.com/kokkos/kokkos/pull/5473 used a C++17 feature, inline static variables.
# We found -fvisibility=hidden could hide these variables such that the supposed globally unique
# variables become local to each file including them and thus have multiple copies (see an example
# at the end of PR5473). It might be a gcc bug thus we also filed at https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107535
# See also an older bug report related to visibility, https://gcc.gnu.org/bugzilla/show_bug.cgi?id=59693
#
# Our workaround here is to git rid of -fvisibility=hidden from Kokkos compiler options, so that petsc
# files including Kokkos headers won't be affected by this flag.
#
# The solution is not ideal in the sense we have to duplicate the same workaround to any external libraries
# using C++17 inline static variables. We have to wait for GNU to clarify this issue.
