rgl

Benilton,

you're compiling for Tiger on Leopard with Leopard X11 settings.  
Unfortunately rgl includes --R_opts from libpng which won't work  
when targeting Tiger. So you have two options:

1) fix rgl, e.g. by using:
sed 's:--ldflags:--libs:' configure > 1 && mv 1 configure && chmod a 
+x configure

(really correct solution is also to add --L_opts, but in our case  
that's taken care of by X11 already)

2) target Leopard instead of Tiger (default for R-devel, but  
requires tweaking for R 2.6.x)

Since you are building 64-bit, I wonder why you are using R-2.6 as  
that is doesn't have Quartz support in 64-bit, unlike R-devel.

Cheers,
Simon

CC to Duncan: to avoid the above it may be a good idea to use -- 
L_opts and --libs only on Darwin, because rpath-like behavior is the  
default linker behavior anyway.

Thanks a lot Simon,

I very much appreciate your kindness in pointing me back to the FAQ.

That got me moving a little bit more and I'm now surprised by the

Any suggestion?

Thank you so much,

Benilton,

please read

(referenced from the R for Mac OS X FAQ) and fix your X11 in case  
you didn't already.

Cheers,

Dear All,

my apologies if a solution was already proposed for this and I  
missed. I didn't have much success with my search, therefore I  
ask here directions on building the rgl package from the source  
using Leopard (and R-2.6.2 RC - 64 bits, built from the source).

I initially tried what I always do to install packages:

install.packages("rgl", dep=T, type="source")

which failed with:

checking for glEnd in -lGL... no
configure: error: missing required library GL

Well, OpenGL is available under Frameworks: /System/Library/ 
Frameworks/OpenGL.framework

and I wonder if anyone could give me some suggestions on how to  
pass and what are the correct 'configure' options to install the  
rgl package.

Thank you very much,

b
