R devel - Aug 2004 - Re: [R] R on gentoo amd64 (gcc 3.3.3) is unstable --- no!

Dear Dirk,
I have had the exactly same problem like Ivo and his solution worked for me.
Hence the USE=f77 flag is NOT a typo but a Gentoo quirk.
As far as modifying the configure script is concerned, I believe that it is
certainly
possible to perform said check (if 'f77 --version == f2c' then die)
only on x86_64 platforms.
And I'd argue it is f2c's fault. AMD64 linux distros have been known to
have troubles of this sort
especially as far as compilers are concerned.


regards
Diman Todorov

Bad idea. 

My Debian configuration, driven from a single configuration, is used on
about a dozen different platforms. One of these, m68k, has a continually
been problematic with g77, which forces us to use f2c. 

And despite your fears, that is working swimmingly for R as well as the by
now 40 or so CRAN packages that are in the distro too, incl the ones like
VR, Hmisc/Design, tseries, ... that contain Fortran code.

I'd argue that it wasn't f2c's fault, but maybe an unlucky mix of
parts of
your toolchain (gcc, binutils, libc, ...).

You are 8 days behind the times -- take a look at the current R-devel.
