rgl revisions to allow dual install
Duncan,
I see now. On PPC you should use
file.exists(system.file("libs/ppc", "aglrgl.so", package ="rgl"))
and, under intel,
file.exists(system.file("libs/i386", "aglrgl.so", package ="rgl"))
instead of just
file.exists(system.file("libs", "aglrgl.so", package ="rgl"))
i.e.
file.exists(system.file(file.path("libs",.Platform$r_arch),
"aglrgl.so", package ="rgl"))
And yes, you have to explicitly set the DISPLAY var under the shell
unless you use xterm.
I have only one doubt, which I'm going to verify: if you override the
DYLD_LIBRARY_PATH var there should be potential problems with tcltk
which is still x11.

It builds fine on PCC and apparently the two libs are in the installed directory. The only problem is that both on X11 term and on R.app always the X11 .dll is taken, so no AGL for me any more. I don't see any conditionals on .Platform$GUI in the loading of the library though.
It's in the .onLoad function in zzz.R:
if ( .Platform$OS.type == "unix" ) {
unixos <- system("uname",intern=TRUE)
if ( unixos == "Darwin" ) {
# For MacOS X we have to remove /usr/X11R6/lib from the
DYLD_LIBRARY_PATH
# because it would override Apple's OpenGL framework
Sys.putenv("DYLD_LIBRARY_PATH"=gsub("/usr/X11R6/lib","",Sys.getenv
("DYLD_LIBRARY_PATH")))
if ( .Platform$GUI == "AQUA" &&
file.exists(system.file("libs", "aglrgl.so", package =
"rgl"))) {
initValue <- 1
rgl <<- "aglrgl"
}
}
}
Does the lib get a different name or sit somewhere else on that
system?
I have the file.exists test in case someone has configured not to
build the AGL version, but maybe the filename is wrong. Do you know a
safe test to see if the lib exists?

and, for the standard shell (i.e. not under xterm), I can open and plot on a x11() device but during demo(rgl)
rgl.open()
Error in rgl.open() : rgl.open failed
rgl.open
The initialization is currently done in .onLoad, and if it fails, no additional attempts are made. I'll see if it's safe to try again. By the way, did you manually set DISPLAY before you opened the x11 device? I get an error in the standard shell when I try that, but Sys.putenv fixes it. Duncan Murdoch
