Above is the gist of brew -config, brew doctor and brew install.
It seems that brew cannot find my system gcc, and the alias it creates for gcc-4.8 somehow fails. I have tried to manually set --cc but got the error invalid value. See gist.

Thank you so much.

The login node on which I am installing this has the following CPU:

Intel(R) Xeon(R) CPU           E5520  @ 2.27GHz

This CPU is rather old and I am not sure how this plays out with the gcc version

okay for now the issue seems resolved.
My cluster has a login node with old CPUs and compute nodes with new CPUs.

  1. I used the solution mentioned in #340 with the following line:
brew install --env=std glibc && brew install gcc

  1. More importantly, I ran the above command on the login node with old CPU. If I do not do this, gcc compiled on compute node would trigger Illegal Instruction error on the login node. Any programs compiled using this gcc on compute node would also throw Illegal Instruction error as well.

  2. As long as I compiled gcc on the login node, any subsequent packages can be compiled with this new gcc on the compute node. This is good since compiling on login node is bad practice.

Out system admin ppl in general advise us to compile things on compute nodes to reduce the pressure on login node. But in this case, I must go for the weakest link.

Still, I don't quite understand why step 1 is needed.

strangely when I go into linuxbrew/lib, and do ls, there is a segfault. This may be related to using different compilers. Otherwise installing packages work for now.

Hi.

I think something is broken in the symlink setup (see #756 (comment)), I need to have a closer look.

This is probably not related to brew.

export HOMEBREW_ARCH=core2 may be useful to you, if you you're compiling on a newer machine and running on an older machine. See #208

Thank you for the help!
