R help - Sep 2005 - Using non-gcc compilers with install.packages()

Hi,

I have built R 2.1.1 on Solaris and OSF1, and used the operating
system's native compiler set. This worked fine. However, when I try
using install.packages() it insists on using g77 etc., which doesn't
exist on those systems.

How can I specify which compilers to use? What about other
compile-time options like LDFLAGS etc.?

NB! Please include me in the CC list, since I'm not a mailinglist
member.

PS. I really like perl's approach to module building. When building
perl modules, it defaults to the same compilers as perl was initially
built with. This seems like a sane approach also for R IMHO.

Cheers,

Indeed, R is pretty sane. Fine tuning is conveniently carried out by
editing the config.site file in the root source directory; LDFLAGS are on
line 138 of the released 2.1.1 source. Which particular packages have you
found showing this behaviour?
