(3.9.2) with the same version of gcc I have installed. The lapack
stuff seems to be giving me troubles, though I'm not too sure why.
No doubt this should be better documented, but if you want to build
gretl against atlas you should use the LAPACK_LIBS environment
variable. For example:
LAPACK_LIBS='-L/your/atlas/lib -llapack -lf77blas -lcblas -latlas' \
./configure <options>
You can't just replace -lblas with -lcblas, because more libraries
are needed with an atlas build, including crucially libatlas.
