Gitorious setup: RSTRING_LEN in rdiscount

Tuesday, June 2nd, 2009

Ran into an issue recently where I was trying to install gitorious on a local RHEL5 system. The site would crash every time I tried to view a repo with the error:

ruby: symbol lookup error: /usr/lib64/ruby/gems/1.8/gems/rdiscount-1.3.1.1/lib/rdiscount.so: undefined symbol: RSTRING_LEN

The solution ended up being the following – In the file /usr/lib64/ruby/1.8/x86_64-linux/ruby.h ( note I’m running on 64bit, on 32bit it’d be /usr/lib/ruby/1.8/i386-linux/ ), add these lines somewhere near the top:

#define RSTRING_LEN(s) (RSTRING(s)->len)
#define RSTRING_PTR(s) (RSTRING(s)->ptr)

After that, uninstall and reinstall rdiscount

gem uninstall rdiscount
gem install rdiscount -v 1.3.1.1

And you should be good to go.

  • Chrome on Windows >

    Seems like Chrome on Windows Vista doesn't like to display the font-face used in this theme - going to have to figure out an alternative!

  • Formatting changes complete >

    So the formatting changes are complete - the pre code looks alot nicer now!

  • Busy busy busy >

    Been really busy at work moving forward with Opsware and trying to reach our milestones. Hopefully I'll have some updates in a bit about what's been going on and some more info on our progress with the tool.

  • Updated Goals and Wishlist >

    I updated my goals and set the new year to 40 years old ( 10 years to go! ) - also updated my wishlist since the big 3 - 0 is coming.

  • Gotta love WP >
