I am trying to link some Fortran code on the Blue Gene (P) using
the xl compilers. My configure script uses
AC_PROG_LIBTOOL
and within that script I see
checking for Fortran libraries of mpixlf95_r...
-L/opt/ibmcmp/xlsmp/bg/1.7/bglib -L/opt/ibmcmp/xlmass/bg/4.4/bglib
-L/opt/ibmcmp/xlf/bg/11.1/bglib -R/opt/ibmcmp/lib/bg/bglib
-L/bgsys/drivers/ppcfloor/gnu-linux/lib/gcc/powerpc-bgp-linux/4.1.2
-L/bgsys/drivers/ppcfloor/gnu-linux/lib/gcc/powerpc-bgp-linux/4.1.2/../../../../powerpc-bgp-linux/lib
-lxlf90_r -lxlopt -lxlomp_ser -lxl -lxlfmath -lpthread -lm
The option, -R/opt/ibmcmp/lib/bg/bglib, is causing trouble with libtool,
as at the final link, I see:
/bin/sh ../../libtool --tag=FC --tag=FC --mode=link mpixlf95_r -qfree
-qsuffix=f=f90 -I../../interfaces/src -w -qalign=natural -qpic -O2

/soft/apps/LAPACK/lapack_BGP.a /soft/apps/BLAS/blas_BGP.a
-L/opt/ibmcmp/xlsmp/bg/1.7/bglib -L/opt/ibmcmp/xlmass/bg/4.4/bglib

-lxlf90_r -lxlopt -lxlomp_ser -lxl -lxlfmath -lpthread -lm -rpath
/opt/ibmcmp/lib/bg/bglib
/opt/ibmcmp/xlf/bg/11.1/bin/bgxlf95_r: 1501-216 (W) command option -ath
is not recognized - passed to ld
ld: unrecognized -a option `th'
I.e., '-R' is converted to '-rpath', which mpixlf95_r does not like.
It seems to separate
this into two args, one of which it keep, but then it dislikes -ath.
Am I doing something wrong?
Thanks...John Cary
