ax_blas_f77_func

Synopsis

AX_BLAS_F77_FUNC([ACTION-IF-PASS[, ACTION-IF-FAIL[, ACTION-IF-CROSS-COMPILING]])
AX_BLAS_WITH_F77_FUNC([ACTION-IF-FOUND-AND-PASS[, ACTION-IF-NOT-FOUND-OR-FAIL]])

Description

These macros are intended as a supplement to the AX_BLAS macro, to verify that BLAS functions are properly callable from Fortran. This is necessary, for example, if you want to build the LAPACK library on top of the BLAS.

AX_BLAS_F77_FUNC uses the defined BLAS_LIBS and Fortran environment to check for compatibility, and takes a specific action in case of success, resp. failure, resp. cross-compilation.

AX_BLAS_WITH_F77_FUNC is a drop-in replacement wrapper for AX_BLAS that calls AX_BLAS_F77_FUNC after detecting a BLAS library and rejects it on failure (i.e. pretends that no library was found).
