config.log doesn't even say. It continues with ==28018==End of process memory map. configure:3474: $? = 1 configure:3481: error: in `/usr/oms/src/libpsl': configure:3483: error: cannot run C compiled programs. If you meant to cross compile, use `--host'. See `config.log' for more details ## ---------------- ## ## Cache variables. ## ## ---------------- ## ... and exit. Regards, Tim
