If I configure in R-patched and R-devel, with the same options to
configure, then R-patched says
checking for ATL_xerbla in -latlas... yes
checking for cblas_dgemm in -lcblas... yes
checking for dgemm_ in -lf77blas... yes
which R-devel says
checking for ATL_xerbla in -latlas... yes
checking for cblas_dgemm in -lcblas... yes
checking for dgemm in -lf77blas... no
This is on the same computer and using the same libraries. Observe
in R-patched we check for dgemm_ and in R-devel for dgemm. Is that
what is intended ?

The configure code has if test "${r_cv_prog_f77_append_underscore}" = yes \ || test -n "${F2C}"; then dgemm_func=dgemm_ else dgemm_func=dgemm fi ... AC_CHECK_LIB(f77blas, $dgemm_func, BLAS_LIBS="-lf77blas $BLAS_LIBS", , $BLAS_LIBS $FLIBS) and r_cv_prog_f77_append_underscore is being set correctly, but only later in the configure. I think that comes from following the autoconf recommended order of tests (libraries, headers, ...), but we need an exception here. -- Brian D.

The recipe has checks for programs checks for libraries checks for header files checks for types checks for structures checks for compiler characteristics checks for library functions and this is mostly based on the idea that everything happens in C. Will move the BLAS tests to section library functions. -k -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
