I am using Ubuntu 6.10.
I am not able to config parallels

It is giving the following error.
checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for gawk... gawk
checking whether make sets ${MAKE}... yes
checking whether to enable maintainer-specific portions of Makefiles... no
checking for gcc... gcc
checking for C compiler default output... configure: error: C compiler cannot create executables



Please help.
Thanks in advance...
