OK, thanks to the timely help of Lyle Johnson (Thanks, Lyle!) I got FXRuby 1.6.4 compiled and installed. Unfortunately I cannot say that I have it running. 1. Using 'gem install fxruby', as per the FXRuby web site's warning, doesn't work. (This was not unexpected.) 2. Building FXRuby 1.6.4 myself from source and installing it ('install.rbconfig', 'install.rb setup' and 'install.rb install') seems to have worked in that it compiled (relatively) cleanly, made the files I'd expect and then put them about where I'd expect to find them. That's where the good news ends, however. When I try a quick test of it, things fail in ways I can't figure out:         $ irb         irb(main):001:0\> require 'fox16'         LoadError: libfxscintilla.so.18: cannot open shared object file:         No such file or directory         - /usr/local/lib/site\_ruby/1.8/i486-linux/fox16.so                 from /usr/local/lib/site\_ruby/1.8/i486-linux/fox16.so                 from (irb):1         irb(main):002:0\> quit                  $ find /usr/local/lib -name [fox16.so](http://fox16.so)         /usr/local/lib/site\_ruby/1.8/i486-linux/fox16.so                  $ ls -l /usr/local/lib/site\_ruby/1.8/i486-linux         total 19M         -rwxr-xr-x 1 root staff 59K 2006-12-11 15:03 [bz2.so](http://bz2.so)         -r-xr-xr-x 1 root staff 19M 2006-12-14 06:48 [fox16.so](http://fox16.so)                  $ find /usr/local/ -name "\*scin\*"         /usr/local/lib/site\_ruby/1.8/fox16/scintilla.rb         /usr/local/lib/libfxscintilla.so.18.1.1         /usr/local/lib/libfxscintilla.so.18         /usr/local/lib/libfxscintilla.so         /usr/local/lib/libfxscintilla.la         /usr/local/lib/libfxscintilla.a         /usr/local/lib/libfxscintilla.17.0.0         /usr/local/lib/libfxscintilla.17         /usr/local/lib/libfxscintilla         /usr/local/include/fxscintilla                  $ ls -l /usr/local/lib/libfxscintilla\*         lrwxrwxrwx 1 root root 21 2006-12-11         20:07 /usr/local/lib/libfxscintilla -\> libfxscintilla.17.0.0         lrwxrwxrwx 1 root root 21 2006-12-11         20:07 /usr/local/lib/libfxscintilla.17 -\> libfxscintilla.17.0.0         -rwxr-xr-x 1 root root 2.5M 2006-12-11         20:07 /usr/local/lib/libfxscintilla.17.0.0         -rw-r--r-- 1 root root 4.4M 2006-12-13         21:22 /usr/local/lib/libfxscintilla.a         -rwxr-xr-x 1 root root 778 2006-12-13         21:22 /usr/local/lib/libfxscintilla.la         lrwxrwxrwx 1 root root 24 2006-12-11         19:25 /usr/local/lib/libfxscintilla.so -\>         libfxscintilla.so.18.1.1         lrwxrwxrwx 1 root root 24 2006-12-11         19:25 /usr/local/lib/libfxscintilla.so.18 -\>         libfxscintilla.so.18.1.1         -rwxr-xr-x 1 root root 3.0M 2006-12-11         19:25 /usr/local/lib/libfxscintilla.so.18.1.1 My inexperienced eyes can find nothing wrong. The [fox16.so](http://fox16.so) file that it claims it can't find is very obviously there. Or, if I'm misreading this, the libfxscintilla.so.18 file it claims it can't find is also clearly present. Permissions seem to all be sane. I can't figure out what it wants from me. What painfully, laughably obvious thing am I missing here? > **···** > > -- > Michael T.

The library file is present, but the application that needs it cannot find it. 1. Check that /etc/ld.so.conf contains the path to the required library directory.

# a whole bunch of stuff about /etc/ld.so.conf Yes, that did it Paul. Thanks. I guess what baffled me was the fact that it was giving the path all the way to the library to say it wasn't there. Weird error message, but this set of incantations made it all work, so I'm happy. > **···** > > On Thu, 2006-14-12 at 17:10 +0900, Paul Lutus wrote: > > -- > Michael T.

It was giving you the path to the FXRuby extension's shared library (in your case, /usr/local/lib/site\_ruby/1.8/i486-linux/fox16.so), and Ruby did know where to find that file. What it couldn't find was /usr/local/lib/libFOX-1.6.so, which is a dependency of the former. The information that Paul provided corrected that latter problem. This is discussed in the FXRuby User's Guide, here:     [http://www.fxruby.org/doc/build.html#tragedies](http://www.fxruby.org/doc/build.html#tragedies) Hope this helps, Lyle P.S.
