1.9.3 fails to install via rvm on OS X Lion

Ruby
#1

So here’s the story

$ rvm install 1.9.3
Installing Ruby from source to:

/Users/darth/.rvm/rubies/ruby-1.9.3-p0, this may take a while depending
on your cpu(s)…

It looks like 1.9.3 doesn’t like my C compiler, but I have no idea why.
Could this be caused by wrong version of Xcode? I’m running on 4.2
(4D199) on OS X Lion.

Well, on Snow Leopard I have 7 flavours of C compiler to choose from
with
Xcode 3. Try passing a flag at ./configure & see which one Lion deems
fit
for purpose (I’ve installed 1.9.3 via rvm so I don’t reckon it’s that).

I had what looks like the same problem last week. After updating the rvm
and reading this SO answer:
http://stackoverflow.com/questions/8032824/cant-install-ruby-under-lion-with-rvm-gcc-issues

I ran the following from Terminal:

$ rvm install 1.9.3 --with-gcc=clang

Hope this works.

Cheers

I struggled with this also. I eventually just resorted to installing
osx-gcc-installer over the top of Xcode 4.2 which seems to have worked.
All the other work arounds like --with-gcc=clang didn’t work for me.

Here’s where you can find osx-gcc-installer:

The problem wasn’t with clang, but with a buggy version of autoconf. It
is fixed now so I’d recommend against your workaround.
