• Compilation error Mac

Dear Florian,

We had some compilation errors on Mac (MacOS 10.13.6, gfortran 6.3.0, Xcode 9.4.1). The error message is

/Applications/Xcode.app/Contents/Developer/usr/bin/make F90=gfortran ../lib/libSPhenoSUSY_EW_ISS.a 
gfortran -c -g -ffree-line-length-none -J../include -I../include   Settings.f90 
ar -ruc -U ../lib/libSPhenoSUSY_EW_ISS.a Settings.o

We were able to fix it by removing the -U flag in the model specific makefile. We do not know, what it does, but the binary runs, so we guess it is not crucial. We just wanted to let you and other potential users know.

Best,
Martin

Dear Martin I was having the same problem than you and I removed the -U flag as you wrote. This fixed the problem but I'm worried why this happens. I'm a Mac user so could it be only a problem for MacOS? Thanks for this post it was very helpful.

(My MacOS version is 10.13.4)

Cheers

I'm not a Mac user, but it seems to be a problem with the gfortran version available in MacOS. The good news are that the flag -U is not crucial. It just speeds up compilation in the case that you changed some files.
