Problems with gfortran-4.2

[Quantisan]

it wouldn't compile under gfortran 4.2. so that installing a newer gfortran instruction is now mandatory. should this be made into a 1-step process? i.e.

brew tap staticfloat/julia
brew install --HEAD julia

would also install homebrew/dupes/gcc --enable-fortran

[staticfloat]

What was the error you got? I've been compiling under gfortran 4.2 for a while.

Also, how did you install gfortran? Through Homebrew?

[Quantisan]

I don't have a record of that error anymore. Yes, I installed gfortran 4.2 through homebrew. Sorry I couldn't be of more help. I guess we'll sit on this for now.

[staticfloat]

No problem. I'm going to edit this issue a bit to try and attract people who have issues with gfortran-4.2, and leave it open in the hopes that someone else who has trouble can come here and help us figure it out.

Well, I have on my todo to rewrite the homebrew gfortran formula to build the gfortran-4.7 from source by ripping the needed parts from the gcc-4.7 formula and delete everything other than gfortran.
Homebrew then, can bottle gfortran, because the build process in lengthy.

Meanwhile, you can brew tap homebrew/versions, brew install gcc --enable-fortran and then set export FC=$(brew --prefix)/bin/gfortran-4.7. (I hope this works, not done this for a while)

It should, those are the instructions in the README, but I'd like people to be able to use the default gfortran in Homebrew if possible.....

... yep, that's why I want to update the gfortran formula. But I had no time today. Shooting for tomorrow.

Homebrew/legacy-homebrew#15941 plz test if you have the time.

re-tested and successfully made a clean install with the formula with gfortran 4.2
