Issue during install of FLEXPARTv9.3.

[jaxelsson]

Dear all,
I receive error once I run the command "make -f makefile.gfortran:

Josefines-MacBook-Air-2:flexpart_code josefineaxelsson$ make -f makefile.gfortran
gfortran -c -O2 -m64 -mcmodel=medium -fcheck=all -fconvert=little-endian -frecord-marker=4 -I/usr/local/include  -DPERFTIMER class_vtable_mod.F90

        ^
make: *** [assignland.o] Error 1

All the paths should be set accordingly in the makefile.gfortran, hence I don't see why there is an error.
Is anyone willing to help me solve it?

Best!

This seems to be a bug in the gfortran implementation on MacOS, as Ignacio was writing on the mailing list:

---

• This may be linked to the migration of Apple to LLVM (the underlying compilation engine of gfortran in Darwin).
• Another usual error message in macs is something like: ld: 32-bit RIP relative reference out of range (2184746534 max is +/-4GB):
• A workaround is to reduce the size of all arrays to the minimum in order to generate a small static executable.
• Notice that -mcmodel=medium should in principle allow large static executables, but in my experience doesn?t work.

I have tried to contact the gfortran developers but I haven't had any feedback.

As it is not a Flexpart bug, I close this ticket (as worksforme, as it should work in a proper environment).
