[R] Patch for rgl with gcc 4.0 in R 2.3.0 on OS X
Hi,
I recently had a problem installing the rgl package on OS X and put together
a simple patch. The patched package is available here:
http://jinome.stanford.edu/files/rgl_0.66-patched_for_gcc4.tar.gz
It can be installed with "R CMD INSTALL
rgl_0.66-patched_for_gcc4.tar.gz" as
normal at the command line.
Also -- as of right now rgl is not in the repository of version 2.3 packages
(or at least did not come up when I ran new.packages() at the R prompt). I'm
not sure if this build error was the problem, but if so this
version now works perfectly. For those who are interested, I have included
details on what exactly went wrong and the fix:
1) What went wrong -- here is the output of the initial build attempt. The
install fails because of an invalid integer conversion, which I eventually
figured out was
due to gcc-4 flagging it as an error, whereas gcc-3 and earlier would have
called it a warning.
[root:/root/downloads/rgl_patch]$R CMD INSTALL rgl_0.66.tar.gz

---------------------
2) The fix is below. It seems that gcc-4.0 does not want to convert an int*
directly to a const GLint*, maybe because it might be possible to
fool around with the underlying variable. To deal with this, I defined a
GLint named viewgl and set it equal to the dereferenced value
of the int* view. I then passed in the address of viewgl to the gluProject
routine. This eliminated the error messages and allowed compilation.

I think this has already been fixed. The rgl repository had a disk crash and is being restored today, but you can see a recent build on my web page, http://www.stats.uwo.ca/faculty/murdoch/software/ We are planning a new release very soon; the disk crash is a bit of a nuisance, though.

It seems that gcc-4.0 does not want to convert an int* > directly to a const GLint*, maybe because it might be possible to > fool around with the underlying variable. To deal with this, I defined a > GLint named viewgl and set it equal to the dereferenced value > of the int* view. I then passed in the address of viewgl to the gluProject > routine.
