Install fails 2

On one of my servers, building CUTEst.jl fails with the message

ln: failed to create symbolic link ‘../usr/lib/libgfortran.so’: File exists

Any idea?

Can you run ldconfig -p | grep gfortran and post the result?

abelsiqueira commented

If there is a locate command on the distribution, try locate libgfortran.so also.

I get

$ ldconfig -p | grep gfortran
	libgfortran.so.3 (libc6,x86-64) => /lib64/libgfortran.so.3
[BLADES:dorban@frontal22:~]$ locate libgfortran.so
-bash: locate: command not found

but note that I installed gfortran with Linuxbrew. I think the sure way to get the correct location of libgfortran is

$ gfortran --print-file libgfortran.so
/home/dorban/.linuxbrew/Cellar/gcc/5.5.0_4/bin/../lib/gcc/x86_64-unknown-linux-gnu/5.5.0/../../../libgfortran.so

so that the gfortran that appears in the PATH is picked up.

gfortran --print-file is so much better than what I have. I'm updating to use it.

If I install CUTEst outside of Julia, I still get an error:

julia> Pkg.build("CUTEst")
INFO: Building CUTEst
INFO: External CUTEst installation found

julia> Pkg.test("CUTEst")

ld: cannot find /home/dorban/.julia/v0.6/CUTEst/src/../deps/usr/lib/libgfortran.so: No such file or directory

This resolves it for me when using an external installation of CUTEst:
