Let me explain the situation a bit better. In SLEPc's configure.py we now (in slepc-dev) create a directory called $PETSC_ARCH in $SLEPC_DIR, then $PETSC_ARCH/lib contains the compiled SLEPc libraries and $PETSC_ARCH/conf contains log files and a "slepcvariables" file. After building, we allow 'make install' if a -- prefix was specified in SLEPc's configure.py (this is not working in slepc-dev yet). The thing is that if $PETSC_ARCH is not set, then we cannot create the $PETSC_ARCH directory. I guess it would be ok to create the files in the root $SLEPC_DIR directory, but this may be confusing for users if they expect a $PETSC_ARCH directory, and more complicated for our makefiles. Any suggestion? The latest SLEPc snapshot is here: http://www.grycap.upv.es/slepc/download/distrib/pre/slepc-dev-081210.tgz Jose
