compiling opengl

[altern]

hi

i am trying to compile opengl for ruby. I found two different distros on
the net, one of them looked like had been prepared for OSX where i work
mostly. I follow carefully the instructions on both with no luck, I
paste below the errors, if anyone could help it would be great.
many thanks


the first time I tried with opengl-0.32f, this one looked like prepared
for OSX

Ordenador-de-r2d2:/Volumes/data/software/ruby/opengl-0.32f r2d2$ ruby
extconf.rb
extconf.rb:36: undefined method `+' for nil (NameError)

----------------

This is the second one with opengl-0.1.32f

Hi,

This is the second one with opengl-0.1.32f [...]
glu.c:8:19: GL/gl.h: No such file or directory
glu.c:9:20: GL/glu.h: No such file or directory

I found that on my OS X system, files like gl.h and
glu.h were buried in some obscure directory, like:

/Developer/SDKs/MacOSX10.2.8.sdk/System/Library/blah/blah

so i made a GL directory locally (right next to
extconf.rb) and copied the following files there:

gl.h
glu.h
glut.h

Hope this helps.... BTW my ruby version on OS X is:

ruby 1.8.2 (2004-12-24) [powerpc-darwin7.6.0]


Regards,

Bill

Hmm... I can't replicate that. try changing the line from

$DLDFLAGS += " -framework OpenGL -framework GLUT -framework
Foundation"

to

$DLDFLAGS = " -framework OpenGL -framework GLUT -framework Foundation"
