Too restrictive configure tests for MPI environment since p4est v2.8.5
jmark opened this issue · comments
Description
Something changed in the build system from version 2.8 to 2.8.5 leading to failed configure-runs on several platforms.
See https://buildkite.com/julialang/yggdrasil/builds/2292 for detailed error logs.
To Reproduce
This PR https://github.com/JuliaPackaging/Yggdrasil/pull/6578/files has all the information.
Amongst others the commit cburstedde/libsc@cfc2ca3 in libsc causes troubles for configuring on some platforms.
From a cursory look, it seems to me like the new MPI tests that were added are implemented sich that they assume that the MPI constants are compile-time constants, whereas the MPI standard only stipulates that they are constant.
Thanks for pointing it out!
