fxruby users - Apr 2008 - fxruby gem install problem

Lyle,

Following up on your suggestion...

"You might want to follow-up on the fxruby-users mailing list at some 
point; sometimes FXRuby questions can get lost in the shuffle here due 
to the high volume of messages on ruby-talk!''

I''ve installed libfox-1.6-dev, and after that attempted install of 
fxruby, with this result:

$ sudo gem install fxruby

I really cannot make sense of this. I''m hoping you can. At least
it''s a
different problem than last time!

Thanks for any help you can offer.

OK, so it looks like the libfox-1.6-dev package depends on something  
called libXrandr.so, which I know is one of the X windows extension  
libraries. I don''t know why the person who built the FOX package for  
Ubuntu wouldn''t have made that an automatically-included dependency,  
but then again I don''t really use Ubuntu on a regular basis.

At any rate, it looks like you need to install that library as well to  
get FXRuby to build. When I google for "ubuntu xrandr", I get some  
hits for the package name "xrandr", so I guess that''s what
you want
(not sure):

	sudo apt-get install xrandr

If anyone else reading is more up-to-speed on Ubuntu, please chime in  
with the correct incantation!

Hope this helps,

Lyle

I can report a success!
I go to it by reasoning that since I had to install (from the ''buntu 
repositories) libfox-1.6-dev, that just possibly the "libXrandr..." 
file(s) might be also there. Looking there for "xandr", I found 
"libxrandr-dev". I installed it, and attempted to install fxruby. It 
went flawlessly. (sigh)

Thanks for your thoughts and help.

Can I assist "the cause" by reporting this issue somewhere? I looked a
bit for some obvious place, and didn''t see it, but then
there''s a lot I
don''t know, so I may have overlooked something pretty obvious.

I guess the first question to ask is whether apt-get is even supposed  
to automatically install dependencies for a package. Surely it is?  
Most package managers work that way, but maybe APT doesn''t.

Assuming it *was* supposed to have installed the dependencies for  
libfox-1.6-dev at the same time that you installed that package, I  
guess the next step would be to try to get in touch with the  
maintainer of that package (again, if Ubuntu/Debian has the idea of  
package-specific maintainers). This problem that you''ve run into
isn''t
a problem with FOX per se --- it''s an issue with how that particular  
deb package is constructed. Again, I''m being vague simply because I  
don''t have much experience with Ubuntu and Debian.

Hope this helps,
