Building ATLAS for various FORTRAN compiler

[Berthold "Höllmann"]

Hello,

I'm trying to build ATLAS for various FORTRAN compiler on one
platform. My ideas was to reuse "libatlas.a", "libcblas.a", and
"libtstatlas.a", and to rename "liblapack.a", and "libf77blas.a" to
"liblapack_g77.a", "liblapack_ifc100.a", "liblapack_ifc101.a", etc.,
and "libf77blas_g77.a", "libf77blas_ifc100.a", "libf77blas_ifc101.a",
etc.

I first call

>  ../configure --prefix=$INSTALL_PREFIX \
        --with-netlib-lapack=/data/tmp/hoel/lapack-$LAPACK_VER/lapack_${OSVER}_g77.a \
        -C if g77
> make build

Then I reconfigure with a compiler specific lapack library and give
the compiler for this Lapack compilation. I do

> ( cd interfaces/blas/C/src/ ; rm -f *.o *.grd )
> ( cd interfaces/blas/F77/src/ ; rm -f *.o *.grd ; make lib )
> ( cd interfaces/lapack/C/src/ ; rm -f *.o *.grd )
> ( cd interfaces/lapack/F77/src/ ; rm -f *.o *.grd ; make lib )
> make build
> make check

...

/usr/local/fitools/bin/ifc71 -O3 -align -mp1 -IPF-fma -openmp -fPIC  -o xsinvtst sinvtst.o \
                   /data/tmp/hoel/atlas3.8.0/build/lib/libtstatlas.a /data/tmp/hoel/atlas3.8.0/build/lib/liblapack.a /data/tmp/hoel/atlas3.8.0/build/lib/libcblas.a /data/tmp/hoel/atlas3.8.0/build/lib/libatlas.a -lm

What is the trick to make this work?

Did you try the directions:
   http://math-atlas.sourceforge.net/errata.html#MultF77

If you have further difficulties, maybe you want to open up a support request,
as described:

Cheers,
Clint

I followed these directions, but it does not cope with the building of
the lapack library.


   make clean
   make lib

in BLDdir/interfaces/lapack/F77/src/ is not sufficient, the routines
from BLDdir/src/lapack and BLDdir/src/blas/*/* are missing in the
generated libraries. I found out, the *.grd files in the
aforementioned have to be deleted to make the generated FORTRAN
work.

I am working on a script that builds tests and renames
libf77blas.[a,so] and liblapack.[a,so] for various versions of the
INTEL FORTRAN -, the PGI FORTRAN -, and the GNU FORTRAN compiler. The
script is not wholly working yet, but I'm making progress.

Kind regards

In order to support the PGI FORTRAN compiler I had to extend the
configuration program to enable linking of C main programs using the
FORTRAN compiler:

>diff -c CONFIG/src/SpewMakeInc.c~ CONFIG/src/SpewMakeInc.c
*** CONFIG/src/SpewMakeInc.c~   2007-10-10 22:40:21.000000000 +0200
--- CONFIG/src/SpewMakeInc.c    2008-02-06 14:36:31.714723356 +0100
***************
*** 673,678 ****
--- 673,680 ----
     fprintf(fpout, "   FCLINKFLAGS = $(FLINKFLAGS)");
     if (strstr(comps[F77_], "ifort") && !OSIsWin(OS))
        fprintf(fpout, " -nofor_main");
+    if (strstr(comps[F77_], "pgf90") && !OSIsWin(OS))
+       fprintf(fpout, " -Mnomain");
     fprintf(fpout, "\n   ARCHIVER = ar\n");
     fprintf(fpout, "   ARFLAGS  = r\n");
     if (OS == OSOSX && MachIsPPC(mach))
