Hmm. You should not have to modify any files at all for this. Just, in a new build directory, do ../source/configure CXXFLAGS=-pg make and you should be set. If you use more than one language, you may want to add CFLAGS=-pg as well. If that still doesn't work, maybe you should show a couple of compiler commands executed by make. Hmm, do you use libtool perchance? Then, you might make LDFLAGS=-Wc,-pg (this will be fixed in Libtool-1.5.22). Cheers, Ralf
