Installing BLAS on a mac OS X Yosemite


Staff member
I'm trying to Install BLAS on my Mac, but every time I run make I get this error (shown below the link). I was trying to follow the instructions on <a href="" rel="nofollow noreferrer">this website</a>:

gfortran -O3 -c isamax.f -o isamax.o
make: gfortran: No such file or directory
make: *** [isamax.o] Error 1

I have no idea what this means or how to fix it so any help would be appreciated. Also I'm trying to install CBLAS and LAPACK so any tips/instructions for that would be nice if you know of a good source...Everything I've found so far is pretty confusing. Also I tried to install ATLAS but it kept not working.
