Re: Compiler Problems?

Hi Thomas and Steve,

Thanks for your clarification. I rewrote this port completely and
update to 3.1.1. Now at least dlamch/slamch are build with -O0.
Hope now it works well. I haven't tried yet with g77 and may not work with it.

% cd /usr/ports/math/lapack
% rm -rf work ; make > & log &
% grep slamch.f log
gfortran42 -O0 -c slamch.f -o slamch.o
gfortran42 -O0 -fpic -c slamch.f -o slamch.o
gfortran42 -O0 -pg -c slamch.f -o slamch.o
