[MacRuby-devel] Fwd: Installing MacRuby HEAD with RVM

[Eric Christopherson]

[I posted this question to the RVM group a few days ago, but haven't
heard back. I know MacRuby users don't tend to use it with RVM, but
I'd like to make this work, since I have had trouble running "system"
MacRuby commands like macgem -- they pick up environment variables set
by RVM and end up doing things like installing/looking for gems in the
wrong places.]

Subject: Installing MacRuby HEAD
To: rubyversionmanager at googlegroups.com


I'm new to this group (hi!). Yesterday I built MacRuby from HEAD,
outside of RVM, and it worked fine. There was a small complication in
that I have a 32-bit Mac, so I built it with rake archs=i386.

Now I'm trying to do the same from within RVM. The first complication
was that I had 'export rvm_make_flags="-j 3"' in my ~/.rvmrc. When
building MacRuby, rake picks up rvm_make_flags, which causes it to
error out because it doesn't recognize -j. So I commented that line
out of .rvmrc.

Next, I found that whatever I tried, RVM would not call rake with
archs=i386, so it was targeting x86_64. I fixed this by editing
~/.rvm/scripts/functions/manage/macruby, changing
'rvm_ruby_make="rake"' to 'rvm_ruby_make="rake jobs=3 archs=i386"'.

This seemed to build MacRuby just fine, but failed to install RubyGems
afterward. Here is the output I get from rvm install macruby-head:

I've taken all my macruby-head logs and put them at
<https://github.com/echristopherson/macruby-head>.

So, I'd like to know:
1. What I need to do to get macruby-head installed; and
2. Whether it would be possible for RVM to be modified to allow .rvmrc
to specify build settings separately for different implementations, so
that e.g. it doesn't try to pass rvm_make_flags to rake as if it's
make. It doesn't seem right to have to modify .rvmrc each time you
compile something.
