openmpi-gcc7 is rebuilt over and over

[EJFielding (Eric Fielding)]

I am using the usual migration procedure to install all my ports after moving to a new MacBook running Mojave. The "restore_ports.tcl" script grouped all the ports that depend on openmpi to the end and now it is rebuilding openmpi-gcc7 over and over as part of the dependency for each port.

This continued for another two hours of rebuilding.

I stopped the restore_ports script and tried to install the "gmt5" port with the "+gdal" variant that then depends on openmpi. Now I see that it found that both openmpi-gcc9 and openmpi-gcc7 ports are broken.

You can always run 'port rev-upgrade' again to fix errors.
The following ports will be rebuilt:
 openmpi-gcc9 @4.0.1+fortran
 openmpi-gcc7 @4.0.1+fortran

Can you tell us (by showing us the output of running sudo port -d rev-upgrade in what way those ports are broken?

[EJFielding (Eric Fielding)]

output of port -d -y rev-upgrade

[EJFielding (Eric Fielding)]

I put the output of 'port -d -y rev-upgrade' into a file and attached it, as it is very long.

[EJFielding (Eric Fielding)]

Maybe this is a clue in the debug output:

openmpi-gcc9 is using libstdc++ (this installation is configured to use libc++)
openmpi-gcc7 is using libstdc++ (this installation is configured to use libc++)
--->  Found 2 broken ports, determining rebuild order
DEBUG: Broken: openmpi-gcc9
DEBUG: Broken: openmpi-gcc7

[jmroot (Joshua Root)]

Could be due to changes in the compiler selection process. Marcus, what's the intended way for configure.cxx_stdlib to be set correctly for ports like these?

[MarcusCalhoun-Lopez (Marcus Calhoun-Lopez)]

In 31b04db7a19d7d0b5b9952943094cbca2620723e/macports-ports (master):

mpich, openmpi: set c++ stdlib for GCC sub-ports

Fixes #59185

[EJFielding (Eric Fielding)]

Thanks Marcus and Joshua!

I ran a port selfupdate and port rev-upgrade and it rebuilt both openmpi-gcc9 and openmpi-gcc7 with no further problems.
