Thank you for your answers !
I'm using Ubuntu, and I installed PETSc 3.0.0, however unlike you, John it's
king of tricky !
When, like you say Ali, i'm trying to install all the libraries from PETSc,
everything is working well exept for blacs.
I'm using this code :
./config/configure.py --with-fc90=gfortran --download-parmetis
--download-mumps --download-blacs --download-scalapack
--with-mpi-dir=/usr/bin/
and the error is :
Downloaded blacs could not be used. Please check install in
/home/seph/petsc-3.0.0-p12/linux-gnu-c-debug.
Into the text file contained in linux-gnu-c-debug, there is one file about
blacs named "blacs"
SHELL = /bin/sh
COMMLIB = MPI
SENDIS = -DSndIsLocBlk
WHATMPI = -DUseMpi2
DEBUGLVL = -DBlacsDebugLvl=1
BLACSdir = /home/seph/petsc-3.0.0-p12/externalpackages/blacs-dev
BLACSLIB = /home/seph/petsc-3.0.0-p12/linux-gnu-c-debug/lib/libblacs.a
MPILIB =
SYSINC = -I/usr/bin/include -I/usr/include/mpich2
BTLIBS = $(BLACSLIB) $(MPILIB)
INTFACE = -DAdd_
DEFS1 = -DSYSINC $(SYSINC) $(INTFACE) $(DEFBSTOP) $(DEFCOMBTOP)
$(DEBUGLVL)
BLACSDEFS = $(DEFS1) $(SENDIS) $(BUFF) $(TRANSCOMM) $(WHATMPI) $(SYSERRORS)
F77 = mpif90
F77FLAGS = -Wno-unused-variable -g $(SYSINC)
F77LOADER = mpif90
F77LOADFLAGS = -Wall -Wno-unused-variable -g
CC = mpicc
CCFLAGS = -Wwrite-strings -Wno-strict-aliasing -g3
CCLOADER = mpicc
CCLOADFLAGS = -Wall -Wwrite-strings -Wno-strict-aliasing -g3
ARCH = /usr/bin/ar
ARCHFLAGS = cr
RANLIB = /usr/bin/ranlib
When i'm looking this code, I realise that blacs is looking for mpich, and I
use openmpi with this line "SYSINC = -I/usr/bin/include
-I/usr/include/mpich2" ?
I'm almost new on linux, I still don't understand my mistake.
But if I follow your advice, the best thing to do is to erase external
libraries, and download and install everything through PETSc ?
