Either disable C++ exception support or send mail to the Open MPI users list. configure: error: *** Cannot continue with both the GCC 10.2.0 & PGI 21.1 compilers. The problem goes away by removing the --enable-cxx-exceptions flag, but (a) is there a solution that doesn't involve removing capabilities, and (b) is this a bug that needs to be fixed in the source? -- Jeff Squyres jsquy...@cisco.com<mailto:jsquy...@cisco.com>
