cosmomc on suns

We are trying to install cosmomc on a solaris 9.0, single cpu computer with the f90 compiler. Is it possible to do this with only LAPACK available (not sunperf) and if so, how do we edit the makefile to do this?

Thanks, Alys.

Certainly CosmoMC only uses a few LAPACK routines - nothing else in sunperf. I don't know what format you have LAPACK in, but probably just a question of putting

-Lpath_to_libs -llapack -lblas

or similar.

Slightly off-topic, but: in my experience it is going to be very slow, i.e. not very useful for anything much beyond debuggin. The following options give you quite a big increase in performance (about 2x, on most modern suns):

-fast -xO4 -xtarget=native -xarch=native

but it will stil be very slow!
