I have searched RedHat's site and can't find any clues to this... I have reviewed the compiler FAQ at linux.org. I downloaded ssh 1.2.22 on a 4.2 box, it compiled without a blink. When I moved the tar file to my 5.0 box, it wouldn't even begin to compile, stating "C compiler cannot create executables." Am I missing something obvious? I tried to see if it was a permissions problem but do not see anything. on RH 4.2 my gcc is gcc version 2.7.2.1 on 5.0 it is 2.7.2.3. Thanks for any hints offered... -Tasha
