[R] rgl.snapshot "failed"

[laszlo kajan]

Dear Roger Koenker,

I have had just the same problem (rgl.snapshot returns "failed") on my 
Fedora Core 6 system.

It took me quite a while to figure out the solution, so I would like to 
post it here to make others' lives easier.

My configuration:

Linux zachariasz.dns6.org 2.6.18-1.2869.fc6 #1 SMP Wed Dec 20 14:51:19 
EST 2006 i686 athlon i386 GNU/Linux

Fedora Core 6

R version 2.4.0 Patched (2006-11-03 r39789)

Package:              rgl
Version:              0.70
Date:                 2007-01-06

What I had to do:

Download the rgl package, install libX11, libX11-devel, libXt, 
libXt-devel, and then run:

--------------------------
R CMD INSTALL --configure-args='--x-includes=/usr/include/X11
  --x-libraries=/usr/lib' path_to_rgl_0.70.tar.gz
--------------------------

The problem is that the ./configure script in the rgl_0.70 package does 
not seem to be able to locate the relevant X include and library paths. 
These have to be given explicitely, as shown.

Hope this will help some in a similar situation.

Best regards,

Laszlo Kajan
