Problem installing Ruby 1.9.2 on Mac OS Lion

Question

I am running Lion, utilizing Xcode 4, have RVM and homebrew installed but am only able to run ruby 1.8.7

    spurvis:~ rogue$ ruby -v
    ruby 1.8.7 (2010-01-10 patchlevel 249) [universal-darwin11.0]
    spurvis:~ rogue$ 

I've read through several threads related to this topic but nothing seems to work for my problem:

    spurvis:~ rogue$ rvm install 1.9.2

The make.log gives me the following info:

Per other suggestions I tried adding export CC=/usr/bin/gcc-4.2 to my bashrc but that didn't solve the problem either.

Please help!

Answer 1

If you want to get rvm install ree with ruby 1.8.7 to work, this solved the problem for me:

# using_gcc for 32btt compiling on lion (solves compatability issues)
function using_gcc() {
  env CC="/usr/bin/gcc-4.2" ARCHFLAGS="-arch x86_32" ARCHS="x86_32" $*
}

#then

using_gcc rvm install ree

Basically just changing "64" to "32" in the other answer.

Answer 2

If you're running a fresh copy of Lion & Xcode 4.2, you're going to need to install the GCC 4.2 dev libraries first - they aren't included in a fresh Xcode 4.2 install.

Then pass the CC="/usr/bin/gcc-4.2" flag when installing your rvm.

Be sure to rvm remove any previous installation attempts first.

Answer 3

Make sure you have the latest xcode available (you'll need to update it if you're running a copy from snow leopard. Update RVM rvm get head and then try again.

I had problems compiling ree but 1.9.2 worked fine, you can try adding this function to .profile in your home directory, it'll compile with gcc (instead of the default LLVM)

# using_gcc for 64btt compiling on lion (solves compatability issues)
function using_gcc() {
  env CC="/usr/bin/gcc-4.2" ARCHFLAGS="-arch x86_64" ARCHS="x86_64" $*
}

Then run using_gcc rvm install 1.9.2
