To: Debian Bug Tracking System <submit at bugs.debian.org>


Package: cmake
Version: 2.4.5-1
Severity: normal

Hello,

cmake cannot find the ruby library .  I am trying to compile some
software (canorus , a music note editor) that uses cmake to create it's
Makefile.  cmake is failing, unable to find the ruby library; it appears
to be looking for the wrong library name.  Here is an example of the
error message it returns:


    donfede at xwing:/tmp/baz/canorus_svn_trunk$ cmake .
    -- Found Qt-Version 4.2.1
    SWIG found, using scripting extensions.
    Ruby Library and Development files found. Ruby extensions enabled.
    Python Library and Development files found. Python extensions enabled.
    CMake Error: This project requires some variables to be set,
    and cmake can not find them.
    Please set the following variables:
    RUBY_LIBRARY (ADVANCED)

    -- Configuring done

I first tried setting and exporting a RUBY_LIBRARY variable in my
envoronment, but that did not help.
    donfede at xwing:/tmp/baz/canorus_svn_trunk$ echo $RUBY_LIBRARY
    /usr/lib/libruby1.8.so

I was able to correct the problem by editing
"/usr/share/cmake-2.4/Modules/FindRuby.cmake" from the cmake package and
adding "ruby1.8" to the list of libraries to search for (that appears to
be how debian packages the ruby library).
