Installed RVM and now my rails server won't start

Question

I had started the Rails app yesterday and got everything working. Then today I decided to go with RVM, as I realized I might have need of it. So I uninstalled all gems, installed RVM and have now a working(?) RVM.

I reinstalled the gems and now my bundle exec rails server crashes

$ bundle exec rails server

[BUG] cross-thread violation on rb_gc()

(null)

Abort trap: 6

Crashreport

I have no idea whats wrong with my installation, as there is no reasonable error' which I could understand. :(

Edit: Gemfile

Answer 1

Try adding gcc-4.2 as your default C compiler to your bash profile:

export CC=/usr/bin/gcc-4.2

Then reinstall your rubies. You need XCode 4.1 to be installed before 4.2, otherwise you won't have gcc-4.2. The easiest way is to uninstall 4.2, and then install 4.1, then upgrade to 4.2.

Answer 2

Great, the answer was to use ruby 1.9.3 instead of 1.9.2 ...

Answer 3

Check out this solution: Error: cross-thread violation on rb_gc()

It looks like this might be an issue with a ruby version difference between your system and RVM. There are a few other articles out there on how to clean this up, like the one below, but I'm not sure which one will work for you:
