[Rd] Compilers on Solaris: beware!
Tue Feb 11 19:14:02 2003
We've just upgraded our Sun compilers from (top line of cc -V)
cc: Sun WorkShop 6 update 1 C 5.2 2000/09/11
(aka Forte 6) to
cc: Forte Developer 7 C 5.4 2002/03/09
although the later seem to be known as Sun ONE these days. A few comments
which may be helpful to other users:
1) It seems that to use C++ code (e.g. package Matrix) you now need to
add -lCstd to SHLIB_CXXLDFLAGS. We will look into making configure do
2) To get libsunperf recognized under v9 (64-bit) options you need
--with-blas="-xlic_lib=sunperf": this is already in the configure script
3) libsunperf now seems to have the LAPACK entry points which were
missing, and works well under 32-bit builds providing both BLAS and
LAPACK, although it does send the occasional error message to stderr.
*However* it has gone from bad to worse for a 64-bit build, with
information enquiries about workspace sizes generating errors. (It is
strange that they do work in 32-bit builds.)
Also gcc 3.2.2 has a fatal optimization bug on Solaris, and code generated
with -O2 causes R's graphics devices to crash (the problem being the
DevDesc* pointer at the end of the arg sequence is not passed correctly).
Avoiding optimization seems a partial cure, and I've reverted to gcc 3.2.
I have updated the R-admin manual, but only in R-devel.
