Description Florian Weimer 2022-11-29 19:36:31 UTC 
As part of the modern C effort, I noticed a few calls to undeclared functions:

/tmp/petsc-2vv1tqcy/config.functions/conftest.c:13: implicit function declaration: sysinfo
/tmp/petsc-4k1fvpta/config.functions/conftest.c:13: implicit function declaration: sysinfo
/tmp/petsc-4qu24htp/config.functions/conftest.c:13: implicit function declaration: sysinfo
/tmp/petsc-4qu24htp/config.packages.MPI/conftest.c:12: implicit function declaration: MPI_Send_init_c
/tmp/petsc-4qu24htp/config.packages.MPI/conftest.c:11: implicit function declaration: MPI_Send_c
/tmp/petsc-4qu24htp/config.packages.MPI/conftest.c:13: implicit function declaration: MPI_Isend_c
/tmp/petsc-4qu24htp/config.packages.MPI/conftest.c:15: implicit function declaration: MPI_Recv_init_c
/tmp/petsc-4qu24htp/config.packages.MPI/conftest.c:14: implicit function declaration: MPI_Recv_c
/tmp/petsc-4qu24htp/config.packages.MPI/conftest.c:16: implicit function declaration: MPI_Irecv_c
/tmp/petsc-be8lusqo/config.functions/conftest.c:13: implicit function declaration: sysinfo

See https://fedoraproject.org/wiki/Toolchain/PortingToModernC#Discovering_Packages_Which_Need_Fixing for the technical background and where these logs are coming from. The full log is here:

https://gitlab.com/fweimer-rh/fedora-modernc-logs/-/blob/main/logs/p/petsc.log

I have trouble figuring out where this is coming from. I opened an upstream issue: https://gitlab.com/petsc/petsc/-/issues/1290

This bug here is mainly to avoid duplicate work on the Fedora side.

Where does this output come from?
Is it the build log of SRPM package in Fedora?

It's a build log, with additional instrumentation for certain kinds of errors:

This bug appears to have been reported against 'rawhide' during the Fedora Linux 38 development cycle.
Changing version to 38.
Comment 4 Florian Weimer 2023-02-08 21:15:23 UTC 
Upstream conclusion is that this is harmless after all.
