i just installed the latest ubuntu version and the ruby-full package from the repository. Additionally i installed rubygems (1.3.7) and tried to do gem1.9.1 install ruby-debug1.9 as mentioned on http://wiki.github.com/mark-moseley/ruby-debug/installation-command-line-version but whatever i do i can't install the gem. Installation terminates with:
Building native extensions. This could take a while... ERROR: Error installing ruby-debug19: ERROR: Failed to build gem native extension.
/usr/bin/ruby1.9.1 extconf.rb * extconf.rb failed * Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.
Provided configuration options:
--with-opt-dir
--without-opt-dir
--with-opt-include
--without-opt-include=${opt-dir}/include
--with-opt-lib
--without-opt-lib=${opt-dir}/lib
--with-make-prog
--without-make-prog
--srcdir=.
--curdir
--ruby=/usr/bin/ruby1.9.1
extconf.rb:2:in require': no such file to load -- ruby_core_source (LoadError)
from extconf.rb:2:in'
Gem files will remain installed in /usr/lib/ruby/gems/1.9.1/gems/linecache19-0.5.11 for inspection. Results logged to /usr/lib/ruby/gems/1.9.1/gems/linecache19-0.5.11/ext/trace_nums/gem_make.out
But installing the ruby_core_source gem hasn't change anything. What is nessecary to install the gem?
