Question

Trying to run ruby on rails framework under nginx+thin, currently working under WEBrick.

I don’t have root access, cause it is hosted at web hosting service.

Till this moment all problems with gems solved w/o root access.

thin requires eventmachine, so:

$ gem install eventmachine

Building native extensions.  This could take a while...
ERROR:  Error installing eventmachine:
        ERROR: Failed to build gem native extension.

Versions of ruby and installed gems:

$ ruby -v

$ gem list

I didn’t really figured out, is the problem in ERROR: Failed to build gem native extension. or in make install ***Error code 71.

Same thing happens trying $ gem install thin

Thanks for advice, Pablo!

Unfortunately, gem_make.out contained only information I provided, nothing else…

Due to rubyforge bugtracker aboud freebsd, I realised that adding this line to .bashrc solves the problem

export RB_USER_INSTALL="$USER"

After source .bashrc I successfully installed both eventmachine and thin.
