Hmm - sometimes sun compilers require the static libm - so the following additional option might work. '--LIBS=/usr/lib64/libm.a'. Otherwise - send us configure.log at petsc-maint at mcs.anl.gov Another note: we always recommend debug build of PETSc for development. One should worry about optimized/performance builds - only after developmenet is done and when performance numbers are captured [perhaps for publishing]. Satish
