Welcome to DejaGNU, a horrible program which should be removed from
reality and sent to spend a thousand lifetimes as a servant to the elder
gods. The cruel ones.
That said, you can try something along the lines of
global target_triplet
set comp_output [g++_target_compile "source.c" "source.o" "object" ""]
set comp_output [g++-dg-prune $target_triplet $comp_output]
if [string match "" $comp_output] {
# Success!
} else {
# failure....
verbose -log $comp_output
}
