I'm using perl v5.8.0 built for i386-linux-thread-multi on a linux PC running Red Hat Linux version 8.0 kernel 2.4.18-14. I'm running a perl script that creates a makefile. I get the following warnings. WARNING: CC is not a known parameter. WARNING: LD is not a known parameter. Setting CC and LD in the shell and exporting them does not help. The creator of the script says it works on other systems/versions, and that these are warnings from perl. Is anyone familiar with these warnings and how I make the parameters known to perl? The make errors out and I'm guessing it's linked to these warnings. Thanks efw
