Johnson ## from the Official Autoconf Macro Archive ## (http://www.gnu.org/software/ac-archive/htmldoc/acx_lapack.m4), ## with the following changes: ## * We also handle HPUX .sl command line specifications. ## * We explictly deal with the case of f2c. Most likely pointless. ## * We test for a LAPACK_LIBS environment variable after checking ## whether LAPACK is already linked (see below). ## * We do not test for the generic lapack_rs6k library (why not?). ## * As we link with $LAPACK_LIBS $BLAS_LIBS $FLIBS $LIBS (in that ## order), we use the same order in the tests. ## * We do not use ACTION-IF-FOUND and ACTION-IF-NOT-FOUND. ## Note that Debian ATLAS has LAPACK libs in /usr/lib/atlas (or $arch ## variants) which should be used if ATLAS is used for BLAS, and not ## found at configure time but used at run time ... ## Note also that (see R-admin) that our main intention is to allow a ## LAPACK-containing BLAS to be used ... there are too many slow or ## broken LAPACKs out there. ## Based on acx_lapack.m4 version 1.3 (2002-03-12).
