I'm sorry, I was very imprecise. Here are the details:
>From the top-level makefile:
include ${PETSC_DIR}/bmake/${PETSC_ARCH}/base
[snip]
info:
[snip]
-@echo "Using C linker: ${CLINKER}"
-@echo "Using Fortran linker: ${FLINKER}"
-@echo "Using libraries: ${PETSC_LIB}"
-@echo "=========================================="
Next, bmake/linux_ppc/base includes bmake/linux_ppc/base_variables which includes
bmake/common_variables which has:
PETSC_SYS_LIB = -L${LDIR} -lpetsc \
${EXTERNAL_LIB} ${LAPACK_LIB} ${BLAS_LIB} \
${MPI_LIB} ${SYS_LIB}
[snip]
PETSC_LIB = -L${LDIR} -lpetscts -lpetscsnes -lpetscsles -lpetscdm -lpetscmat \
-lpetscvec ${PETSC_SYS_LIB}
[snip]
include ${PETSC_DIR}/bmake/${PETSC_ARCH}/base.site
>From bmake/linux_ppc/base.site (after the build has started and debian/rules has
replaced PETSC_MPI=petsc_mpi with PETSC_MPI=mpich):
PETSC_MPI=mpich
# For mpich: (woody mpich uses /usr/lib/mpich/lib, potato the longer dir)
ifeq ($(PETSC_MPI),mpich)
MPI_HOME = /usr/lib/mpich
MPI_LIB = -L${MPI_HOME}/lib -L${MPI_HOME}/build/LINUX/ch_p4/lib -lmpich
MPIRUN = /usr/bin/mpirun.mpich -machinefile /etc/mpich/machines.LINUX
MPI_INCLUDE = -I/usr/lib/mpich/include
-I/usr/lib/mpich/build/LINUX/ch_p4/include
endif
And the output from the top-level info: target:
[snip]

Note the -L{MPI_HOME}/build/...
Again, this behavior began in powerpc unstable between Feb 2 (when I uploaded
-3_powerpc) and Feb 20 (when I first tried to build -4 and noticed this problem
existed in -3 and -4); and in alpha testing between Feb 15 (when I last built
PETSc and ran benchmarks) and the build attempt today.
Okay, what's really odd, is that the installed -dev packages on the alpha with the
same bmake files as the source package (just diffed them) work fine, but when I
try to build new packages it screws up! That's really bizarre. (Yes, I've
confirmed that during the package build, PETSC_DIR points to the source directory,
not /usr/lib/petsc of the installed package. That too is printed by the info:
target, and shows up in the -L flags above.)
That's all I know,
-Adam P.
