The wily st.h (on Ubuntu and rvm)...

Hi there!

This gem is a great idea. It could definitely come in handy backporting some Ruby1.9 libs.

Unfortunately, it doesn't build against Ubuntu and rvm's Ruby 1.8. I believe it's because of the location of the header files.

Ubuntu:
/usr/lib/ruby/1.8/i686-linux/st.h

rvm:
~/.rvm/rubies/ruby-1.8.7-head/lib/ruby/1.8/i686-linux/st.h

As you can see, similar locations. I don't know anything about ruby's build system, so I can't suggest a solution. I can tell you that I haven't had a problem with any other gems linking against ruby, so there's probably a standard solution to this.

Thanks!

Well, this might be a problem with the build setup. If mkmf works properly, it should be setting the include path to the correct prefix in either case. Can you provide more information about the failure? Your makefile? The failure log?

Can you find the st.h file for me in a Ubuntu install?

epitron commented

I just realized that I was building against debian squeeze's ruby1.8, not Ubuntu. Ripper does work on Ubuntu.

Debian's st.h is in:
/usr/lib/ruby/1.8/i486-linux/st.h

Any updates on this? I can't install this gem with rvm (ruby 1.8.7) in ubuntu 11.04

Thanks!

lsegal commented

I've just merged some pull requests, if you checkout master (or update your local copy) does it fix?

quicklizard commented

Thank you. Your last commit solves the problem for me: Ubuntu 11.04, ruby 1.8.7, ree (ree-1.8.7-2011.03), rvm 1.5.2

lsegal commented

Thanks, this fix is in 1.0.3
