buildin rmagick gem and how to avoid memory leakThu, Apr 22, 2010
If you running Arch Linux you stay up to date all the time! As a down side - frequently broken dependencies once a system lib gets updated. Rmagick gem is a good example!
Once you get an error:
RuntimeError (This version of RMagick was created to run with ImageMagick 6.6.0 but ImageMagick 6.6.1-4 is installed on this system. You should either 1) Configure and build RMagick for ImageMagick 6.6.1-4, or 2) download ImageMagick 6.6.0 from file:///usr/share/doc/ImageMagick-6.6.0/index.html and install it
it’s time to rebuild the gem with its native extension which depend on the updated lib.
Update itself is trivial:
$ sudo gem uninstall rmagick -v 1.15.14 $ gem install rmagick -v 1.15.14 -- --disable-htmldoc
–disable-htmldoc option is essential if you don’t want spend another couple hours waiting for gem to get built.
Turns out that htmldoc building is a huge leak! It’s fixed in latest rmagick gems but for the gem leaking was the case.
PS: I’m using Rmagick v1.15.14 because of our project dependencies.
