#41687 assigned defect

gcc48 @4.8.2 fortran does not work

Reported by: ralph@… Owned by: macports-tickets@…
Priority: Normal Milestone:
Component: ports Version: 2.2.1
Keywords: mavericks Cc:
Port: gcc48

Description (last modified by ryandesign (Ryan Schmidt))

I have had a lot of problems trying to build arpack, atlas etc with gcc48. Here is a simple test case which shows what is up. I am not sure whether this is the same as #41555, but I can't rebuild gmp from source either, so I am stuck. Note this is with a fresh install of the prebuilt gcc48.

	program foo
	real, parameter :: bar = sin (12.34 / 2.5)
	end program foo

Try to compile it with

x86_64-apple-darwin13-gfortran-mp-4.8 foo.f

I get the result

ld: could not parse object file /opt/local/lib/gcc48/libgfortran.dylib: 'Invalid bitcode signature', using libLTO version 'LLVM version 3.4' for architecture x86_64
collect2: error: ld returned 1 exit status

The same command works fine for me on Mavericks.

Probably because you do not have llvm3.4 installed too, I would guess.

After removing gcc48 llvm-3.4 cctools ld64 and libgcc, then reinstalling gcc48 and libgcc, this now works for me too. This sems to be because instead of llvm-3.4 being reinstalled, llvm-3.3 is installed. So, there is definitely some nasty interaction between gcc48 and llvm-3.4
