[aspect-devel] Error compiling Aspect

How old is this version? To compile ASPECT you need a somewhat recent
development version or you need to go back to 8.4.2.

Yes, this warning sounds like the compiler changed between configuring
deal.II and compiling now.

Are you compiling all dependencies (p4est, trilinos, deal.ii, ...)
yourself or are you using a module? Are you sure that you always have
the same modules loaded? Are you compiling everything on the same
"kind" of node (here in Clemson the login node has a different
architecture for example)? Can you please check your CXX_COMPILER from
the detailed.log in the ASPECT build directory and the deal.II build
directory and compare?
