Building R from the source

Hi Everyone,

when building (say) R-2.4.0 from the source, is it still the
recommendation to use GCC 3.4?

It depends on your unstated OS.  There are recommendations in the R-admin 
manual, and those I wrote are still current.

Often one cannot easily mix systems based on gcc3 and gcc4: there are a lot 
of API incompatibilities, at least on 64-bit systems.  So if you have a 
gcc4-based Linux distribution (for example), use its 'native' compilers.

If you want more detailed advice, please give fuller details including 
your exact OS and what compilers you have available to you.
