petsc: FCFLAGS and FFLAGS are both set, but with different values

[ryandesign (Ryan Carsten Schmidt)]

​petsc does not build:

*******************************************************************************
         UNABLE to CONFIGURE with GIVEN OPTIONS    (see configure.log for details):
-------------------------------------------------------------------------------
FCFLAGS and FFLAGS are both set, but with different values (FCFLAGS=-pipe -m64, FFLAGS=-pipe)
*******************************************************************************

Likely the same base issue as #57358.

I can confirm the workaround in #57358#comment:11 worked for me. I installed petsc with these variants:

port -u install petsc +gfortran -mpich +openmpi +sundials -accelerate +openblas

where I already had openmpi-default +gcc8 installed.

To this day the problem persist

I tried the workaround in #57358, i've guessed that the position in which the line needs to be add in the file (opt/local/../../math/petsc/Portfile) is irrelevant. If that is the case (and if didn't screw anything up) is there another solution to this problem? I tried your variants, as well as without any, can't understand what the problem is (by the way, no other ports are installed, just the dependecies needed for petsc)

Yeah, one of the problems with doing this all in base. If you don't need fortran binding (it doesn't seem like you do since you're not using mumps), then you can just remove the +gfortran variant.

It still does not compile, even without the +gfortran. Any other workaround?

Has duplicate #58530.

I was finally able to install petsc using

port install petsc +mumps

after I added the following to lines to the Portfile:

configure.fcflags   -Os
configure.fflags    -Os -m64

I had to play with the order of the flags. "-Os -m64" is not the same as "-m64 -Os".

This clearly is a hack and I'm sure there is a more elegant way of doing this, but I'm not well versed in Portfile writing.

This has been fixed in a released version of MacPorts (see the discussion in #57358).
