Cannot find BLAS/LAPACK in nonstandard locations

[Michele Vallisneri]

Hello, I’m trying to compile tempo2 on a cluster without system-wide Blas and lapack. I can install this myself, but cannot successfully point tempo2 to them. It seems the --with-blas and --with-lapack configure options are not sufficient, in that the packages are recognized, but I get failures at link time (e.g., the link command does not include -llapack, or -L<relevant lib dir>) .

Thanks for supporting free scientific software!

Thanks for this info. Certainly a bit strange that it doesn’t link properly. For a short-term fix I suggest just adding the required paths (-L options) to your LDFLAGS and see if that helps. For a better fix I suggest looking at the config.log (or posting it here) to see what it says regarding lapack etc. Personally I use openblas/openlapack, which seem to work ok, but obviously there are many different lapack implementations so I guess it isn’t detecting something in your system version.
