Answer 1

Ok, I found the solution.

1. Remove Xcode.
2. From here I downloaded the package for Mountain Lion.
3. Install downloaded osx-gcc-installer.
4. Install Xcode (and command-line tools).

That is all.

Answer 2

It looks like rvm did not find apple-gcc42 installed with brew.

Make sure gcc-4.2 is available via PATH, or run installation with path to it:

rvm reinstall 1.8.7 --with-gcc=/path/to/brew/apple-gcc42/gcc-4.2

---

EDIT1: just checked, RVM searches also for gcc-apple-4.2 so if it is on PATH it will be automatically used by RVM - this was updated in RVM 1.16.8.

Answer 3

I tried the GCC package, installing/uninstalling Xcode, etc, but what I think worked was:

rvm get stable

(The response included another command:

sudo sed -i'' -e "s#rvm_configure_env=('LDFLAGS=-L/opt/sm/pkg/active/lib CFLAGS=-I/opt/sm/pkg/active/include CPATH=/opt/sm/pkg/active/include')#rvm_configure_env=('LDFLAGS=-L/opt/sm/pkg/active/lib' 'CFLAGS=-I/opt/sm/pkg/active/include' 'CPATH=/opt/sm/pkg/active/include')#" /etc/rvmrc

)

I'm pretty sure this was what led to being able to successfully:

rvm install 1.9.3
