Hi,
I''ve installed and used wxRuby on Win32, and am
trying to install it on Linux for the first time.
I''m running Fedora Core 6. Here is what I have
installed, but as shown below, when I try to
load wx, I''m told it cannot be loaded.
I get the same error when trying to run some
of the sample wxruby scripts. Sorry for the
newbie question, but am I missing something
obvious? Thanks in advance. Roggie

If you''ve installed wxruby as a gem, you must ensure that the rubygems library is loaded before you load wx. If this doesn''t help, please could you try doing require ''wxruby2'' after requiring rubgems, and sending us any error message you get. thanks alex
As a followup to my earlier post, it was requested
that I try loading rubygems first. Here is what
I get on Fedora Core 6 (and for additional info,
I get the same thing on a Gentoo Linux setup).

Apparently Fedora comes with SELinux enabled by default, which is what is stopping the wxruby library loading and giving this error message. I have no clue what SELinux is or is meant to do, but searching for "cannot restore segment prot after reloc" Fedora turned up a number of pages with what look to be likely solutions. hth alex
