openmpi-devel-gcc9 @4.0.1: error: ptrdiff_t type is not available

[oliviermarti (Marti)]

Mac OS X 10.14.6

XCode 12.2.1

MacPort 2.6.2, fresh install from scratch (all previous MacPort port and files removed as explained inhttps://guide.macports.org/#installing.macports.uninstalling)

sudo port install gcc9 # OK
sudo port select --set gcc mp-gcc9 # OK
sudo port install openmpi-devel-gcc9 +fortran

Last command fails with

I have exactly the same defect with gcc8 and gcc7.

please attach the main log file from the build, which will be referenced by the error message. It is usually best if you clean first, try again, and then attach that clean log for us to see:

sudo port clean openmpi-devel-gcc9
sudo port -v install openmpi-devel-gcc9

The buildbots seem to like it, for the most part... <​https://ports.macports.org/port/openmpi-devel-gcc9/builds>

Replying to kencu:

Done. Sorry for missing this step.

There is a comment here near the bottom of the page by Jeff Hammond <​https://github.com/Homebrew/homebrew-core/issues/40676> that suggests a workaround you might try.

[oliviermarti (Marti)]

Hi,

Sorry to disturb again. I'm still stuck with OpenMPI.

I've tried to understand the workaround of Jeff Hamond. My skill and knowledge about both HomeBrew and MacPort are too light for that. I can't find where in the MacPort files I have to do something.

I've upgraded to XCode 11.3, and I've got exactly the same error.

Since we no longer offer Devel ports for openmpi and mpich - nor do we support upstream compilers for these ports, due to the potential fragility - this ticket is no longer relevant. Closing.
