[Rd] Re: [R] R on gentoo amd64 (gcc 3.3.3) is unstable --- no!

peter/brian: thank you for the help. i can now report that gentoo amd64 can compile R just fine, too; it requires the f77 USE flag and a gcc compiler rebuild first, though. I also went to gcc 3.4.1. my segfault troubles earlier were caused by my use of f2c.

suggestion: would it be possible to add a code snippet that tests whether the user is trying to compile with f2c---and if so, bombs the installation? (if "f77 --version == f2c" then die) I know the problems are not R's fault, but it can percolate into R and it can protect people like myself.

regards,

/ivo

PS: I am still looking for an R wizard who would be interested in coauthoring an "R cookbook" ala the "perl cookbook" with me...

As I read the posting guide this is not a help request and not of 
general
interest, so diverted to R-devel.

Several people including me have built R on AMD64 with 3.3.3.  That's 
the
compiler of Fedora Core 2, and of whatever version of SuSE (perhaps 
9.0)
we have on our 110-processor cluster.  I am currently use 3.4.1.

Your error is in Fortran, and we have seen Fortran errors in earlier
versions of the gcc collection so it's the g77 version that is relevant.
