Hi all,
I'm wondering if/where I can go to tell R to use a specific version of
my gcc compiler when installing packages from source, via
`install.packages("...", type='source')` or when running `R CMD
INSTALL some_source_packge.tar.gz` from the command line.
The reason I ask is because I've downloaded gcc-4.4 from HPC/OSX[1],
and it unfortunately puts the compilers in /usr/local/bin/gcc, w/o
version info (it would be nice if it were /usr/local/bin/gcc-4.4). R
tries to use this when compiling, but these compilers do not support
the "-arch=..." flags, so it bombs.
I've been hunting around in the tools:::.install_packges code and also
the "R Installation and Adminstration"[2] document, but can't find
what I'm looking for. I have a feeling that perhaps I can put
something into my ~/.R/Makevars, or ~/.R/Makevars-i386-apple-
darwin8.11.1 file, but I'm just taking stabs at the dark, so not
having much luck.
I can work around this by temporarily removing /usr/local/bin from my
path when trying to `R CMD INSTALL` packages by source, but I was
hoping there might be a more elegant solution. The fact that
installing by source gets the `make` command from the system
environment makes me a bit hopeful, but I'm not really sure.
Thanks for any help,
-steve
