Xcode 9.3 (9E145) and macOS 10.14.4.
I installed CLT and the SDK headers as you instructed. Also gfortran 8.2 from GitHub <
https://github.com/fxcoudert/gfortran-for-macOS/releases>.
I removed the symlinks following David’s email and tried compiling with clang but I get two warnings and a similar error but for gfortran:
Testing the clang compiler:
clang -fPIC -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -o testp testp.c
ld: warning: URGENT: building for OSX, but linking against dylib (/usr/lib/libSystem.dylib) built for (unknown). Note: This will be an error in the future.
OK
Testing the clang++ compiler:
clang++ -fPIC -o testp testp.cpp
ld: warning: ld: warning: URGENT: building for OSX, but linking against dylib (/usr/lib/libSystem.dylib) built for (unknown). Note: This will be an error in the future.URGENT: building for OSX, but linking against dylib (/usr/lib/libc++.dylib) built for (unknown). Note: This will be an error in the future.
OK
Testing the gfortran compiler:
gfortran -fPIC -O0 -o testp testp.f
ld: malformed file
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/lib/libSystem.tbd:4:18: error: unknown enumerated scalar

./configure2: line 2573: ./testp: No such file or directory
Error: Unable to compile a Fortran program using gfortran -fPIC -O0
Please check your compiler settings and configure flags.
Configure failed due to the errors above!
I suppose I should upgrade to latest Xcode first and try again?
Thanks,
Reza

I won’t be able to do so until next week either unfortunately. In the meanwhile, you can always try removing the symlinks for home-brew versions and configure using
