In a previous thread I had problems on openSuse 10.2 building R with
optimisation and discovered that if I wanted
optimisation I need to turn on
-fstore -fsimple1 (the first is to force storage on some Fortran routines , the
second is to ensure IEEE arithmetic,
with some optimisation).
That wor
Thanks for all the replies:
Dr. Ripley gets it right:
I want -fast which turns on nofstore which caused the infinite loop and also
pointed out non-IEEE arithmetic.
On SUSE 10.2 I used -fast -fstore -fsimple=1 which fixed both problems and
still optimised:
make check passed and I get for gcc4

The R-admin manual did tell you not to do that!
When using the Sun compilers do @emph{not} specify @option{-fast}, as
this disables @acronym{IEEE} arithmetic and @command{make check} will
fail.
That was for Solaris and SunStudio 11, but I presume these are basically
the same compilers.
I would like to Build R-2.5.1 on OpenSUSE 10.2 using the SunStudio 12
compilers(http://developers.sun.com/sunstudio/index.jsp)
R builds and passes make check fine without optimising. However, when I try to
compile with optimisation turned on
(-fast) the build gets stuck in an infinite loop at th
