Dear all,

I tried to install the package rgl on 10.7. Here's the output:

Apparently, I'm missing the "GL" library. But how can I install it? I searched for it on the web and mainly found that the Mac should have Open GL already installed (?).

Are you sure you installed X11 and Xcode4?

yes, both are installed.

I have no problem with the *configuration* on vanilla Lion.

I installed about 30 packages today, everything worked fine. Hmmm... seems challenging to detect where the problem is.

If you want to do that, have a look at rgl/config.log - it will tell you what went wrong.

There is still an issue in the rgl 0.92.798 code (opengl.hpp), though, it's including AGL/* instead of OpenGL/* which fails (hence CC to Duncan), but that's at compilation stage, not configuration.

BTW: why don't you just use
install.packages("rgl")
that works on Lion as well...

I installed all packages from source since I installed R from source and I remember reading somewhere that one should do it this way since the binaries are built to work with CRAN's binary installation of R. But if this does not create problems (please let me know), I'll give it a try.

As long as your configuration is compatible (essentially you have to set r_arch properly) it works. It's not guaranteed to work if you use different compilers.

install.packages("rgl", configure.args="--r_arch=x86_64")

I just remember something: I installed the 64bit R version. Is this a problem for rgl?

No.

[PS: while at it - I'm a bit confused about the current setup, though, since it uses the (non-X11) OpenGL framework yet links X11;  Also it crashes when GLX is not supported (e.g. ssh tunneling). I remember that at some point in the past it was building native and X11 versions but what is left is some mix of both...]
