3.2. Platform Notes

• Systems that have been tested are:

  • Linux (various flavors/distros), 64 bit (x86, ppc, aarch64), with gcc (>=4.8.x+), clang (>=3.6.0), Intel, and Portland (be sure to also see the Compiler Notes section)

  • macOS (10.14-10.15, 11.x, 12.x), 64 bit (x86_64 and M1) with XCode compilers

• Other systems have been lightly (but not fully) tested:

  • Cygwin 64 bit with gcc

  • ARMv6, ARMv7, ARMv9

  • Other 64 bit platforms.

  • OpenBSD. Requires configure option``–disable-dlopen`` with this release.

  • Problems have been reported when building on FreeBSD 11.1 using the clang-4.0 system compiler. A workaround is to build PMIx using the GNU compiler.

Note

32-bit environments are no longer supported.
