fxruby users - Aug 2005 - Some problems with FXRuby 1.4.2, 1.4.1

I''m probably doing something wrong, but I experience several issues
trying to
install FXRuby here [using gems]

1. How do I specify where to look for FOX?

   I tried --with-fox-include and --with-fox-lib but they give me an error:

  "gem install fxruby --force --with-fox-include=/usr/include/fox-1.4 
--with-fox-lib=/usr/lib"
	
  which results in:

  "ERROR:  While executing gem ... (OptionParser::InvalidOption)
    invalid option: --with-fox-include=/usr/include/fox-1.4"

2. I''m getting this error while its building FXRuby

  In file included from include/FXRuby.h:747,
                 from include/FXRbCommon.h:90,
                 from core_wrap.cpp:588:
include/FXRbIconSourceVirtuals.h:15: error: invalid covariant return type for 
`virtual FX::FXImage* FXRbIconSource::loadImage(const void*, const 
FX::FXString&) const''
/usr/local/include/fox-1.4/FXIconSource.h:109: error:   overriding `virtual 
FX::FXIcon* FX::FXIconSource::loadImage(const void*, const FX::FXString&) 
const''
make: *** [core_wrap.o] Error 1

Ok, forget problem #2. A fresh install of FOX fixed that problem.

How about if you build from a tar ball? This just sounds like gem
doesn''t know how to pass on options (I don''t see any
indication in `gem
help install` otherwise).

Well, the possibly good news is that I *think* that 
/usr/include/fox-1.4 and /usr/lib are one of the standard directory 
pairs that the build script will check for a FOX installation, so you 
can *probably* get by with just doing:

	gem install fxruby

Despite this, your experiment shows that, apparently, they''ve changed 
how you pass command-line options through gem install, so I need to 
follow up on this with the RubyGems developers. If you''re unable to 
build the code by doing "gem install fxruby", fall back to the tarball
build for now, per Joel''s suggestion.

Back up a little bit, I''m confused. Are you doing this from irb? How do
you know that the require calls are returning false? Have you tried to 
just run one of the examples (e.g. "hello.rb") to see what happens?

OK.

Taking the problems one at a time, I''m curious about why the require of
"rubygems" is failing. Have you actually installed RubyGems yet?
It''s
not part of the standard Ruby distro yet, so that would be something 
that you''d need to download separately and install first.
