Alex,
a pre-built GNU gcc including gfortran is available via MacPorts, and
probably via Homebrew as well.
Build instructions are in the INSTALL file at the root of the source tree.
You will not find anything explicitly setting that erroneous flag for
Fortran compilations in our build scripts, as I stated it is probably a
CMake issue, which may need to be addressed by the CMake developers.

Hi Bill,
Thanks for the quick response. I tried to roll back to pre-v8
gfortran, couldn’t find v7 pre-built and didn’t want to go down that
rabbit hole of building it.
I tried again with gfortran 6.3.0 and got the same error however-

This might be a stupid question but is there a build-guide for MacOS
X? I feel like I’m missing something simple here unless there is only
one person in the world who can build the Mac code. :)
In the meantime if I can motivate myself to enter the hell that is
CMake, I will see if I can suppress this option from the gfortran make.
It’s been awhile since I’ve had the misfortune of working with CMake.
;-) A necessary evil for truly cross platform work.
Thanks again for your help,

Hi Alex,
thanks for that. We currently do not recommend using a gfortran
version >= 8 on macOS, this is due to some known issues with our code
for which fixes are a WIP. With gfortran v7 that compiler diagnostic
message is only a warning, which is how our build gets passed it. The
passing of -Xclang to the Fortran compiler is not done directly by
us, I guess it is a CMake issue which we have not been too concerned
about yet.

Hi there,
I’m running into an error in the fortran portion of the WSJT-X

I’m not sure why -Xclang is being passed to the fortran compiler.
Calling gfortran with a test file and -Xclang option generates
the same error.
I’m wondering if I misconfigured the project or perhaps I’m using
the wrong tool chain?
Any help would be appreciated,

Hi Alex,
which Fortran compiler are you using and what version?
