Can't install Ruby or Rails using RVM : ERROR: There has been an error while running configure. Halting the installation?

Are you missing usr/include/pthread. H on your system?

Are you missing /usr/include/pthread. H on your system?

No. Emacs /usr/include/pthread. H did work – user974407 Oct 1 at 11:27 Why would I be missing pthreads?

It doesn't seem to make any sense. – user974407 Oct 1 at 11:42 I misread you response ... yes, if you have the header than configure should find it – nhed Oct 1 at 13:11 Also, you're not using RVM. That is using the SYSTEM'S ruby and NOT rvm.

You need to actually select a ruby to use (rvm use 1.9.2-p290) and create and use a gemset (rvm --create use 1.9.2-p290@mygemset) and also select a default ruby and gemset (rvm --create use 1.9.2-p290@mygemset --default). Please also make sure you followed the entire install information from rvm.beginrescueend. Com/rvm/install/ and NOT some external tutorial you found on the net.

Then you need to populate your gemset with at least bundler such as rvm 1.9.2-p290@global exec gem install bundler && gem install rails – deryldoucette Oct 1 at 18:20 One last note, make sure you are using Xcode 4.1 and NOT Xcode 4.2 as Xcode 4.2 is still pre-release and doesn't compile a lot of things correctly (Apple still has it as a developer's preview). Note that RVM does NOT support its use. – deryldoucette Oct 1 at 18:23.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
