fxruby users - Oct 2006 - Build error: Debian testing, libfox1.4, FXRuby-1.4.7

I''m getting compile errors when attempting to build FXRuby 1.4.7.
This happens when installing using gems, or when installing from
source:

g++ -I. -I. -I/usr/lib/ruby/1.8/i486-linux
-I/home/wayne/lab/fox/FXRuby-1.4.7/ext/fox14 -DHAVE_SYS_TIME_H -DHAVE_SIGNAL_H
-I/usr/local/include/fxscintilla -I/usr/local/include/fox-1.4 
-I/usr/include/fox-1.4 -fPIC -Wall -g -fno-strict-aliasing -O2  -fPIC -O0
-Iinclude   -c fx3d_wrap.cpp
fx3d_wrap.cpp: In function ''FX::FXVec3f FXVec3f_normal(const
FX::FXVec3f&, const FX::FXVec3f&, const FX::FXVec3f&)'':
fx3d_wrap.cpp:705: error: no matching function for call to
''normal(const FX::FXVec3f&, const FX::FXVec3f&, const
FX::FXVec3f&)''
fx3d_wrap.cpp: In function ''FX::FXVec3f FXVec3f_normal(const
FX::FXVec3f&, const FX::FXVec3f&, const FX::FXVec3f&, const
FX::FXVec3f&)'':
fx3d_wrap.cpp:708: error: no matching function for call to
''normal(const FX::FXVec3f&, const FX::FXVec3f&, const
FX::FXVec3f&, const FX::FXVec3f&)''
...

My environment:

        Debian testing
        Ruby 1.8.2-1
        Fox 1.4, from Debian packages libfox1.4 and libfox1.4-dev
          (package versions 1.4.31-2+b1)

Any idea what''s up?

No doubt I''ve left off the one thing that would help you figure out
what I''m doing wrong.  Requests for more information will be gladly
acted upon.  RTFM''s including a link to the FM would be most welcome.
And clues, should you have any, will be gratefully received.

Well, I guess for starters, can you confirm that Debian installs the  
FOX include files into either /usr/local/include/fox-1.4 or /usr/ 
include/fox-1.4? I think the compiler is in fact seeing the include  
files, but I just wanted to rule out that possibility up front.

I''m also wondering if it has to do with the "friend
injection" change
made in GCC 4.1, which I know broke some earlier versions of FOX.  
Jeroen put a patch in FOX 1.4.32 to address this problem. Do you know  
which version of FOX Debian is using for their libfox1.4 packages?

I find bunches of files in /usr/include/fox-1.4

My g++ is version 4.1.1.

Fox 1.4.31.  With Debian version numbers, everything before the dash
is the original package''s version.

I see that Fox version 1.4.34 is in Debian unstable.  I''ll install it,
see if it fixes things, and let you know.

That did it.  After installing Fox 1.4.34, FXRuby 1.4.7 compiled from
source and installed alright.  "require ''fox14''" now
works.

Strangely, I couldn''t get it to install using gem, which complained
"make: Nothing to be done for ''install''.".  No
worries, since
it installed from source alright.

Thanks for the help!

There is a known (and reported) bug with the latest release of RubyGems:

	http://rubyforge.org/tracker/? 
func=detail&aid=4948&group_id=126&atid=575

I believe that a fix for this problem has been checked into the  
RubyGems CVS, so it should be corrected in the next RubyGems release.
