Hello, Last week, I changed from Tiger (10.4.11, Xcode 2.4.1, MP 1.6.0) to a fresh install of Leopard (10.5.2 and Xcode 3.0). I'm now finding that /usr/bin/gprof does not profile a program compiled with gfortran- mp-4.2 and its -pg flag. I'm pretty sure this worked in the past (am I wrong?). I thought perhaps it had to do with the system's gprof not being compatible with macports-supplied compilers, so I installed the binutils port (as gprof is provided by binutils on my Fedora box), but no auxiliary gprof was installed in /opt/local/bin. Does anyone have gprof working with port gcc42's gfortran in Leopard? How can I make this work? In the meantime, I started using Xcode's Shark, which is an incredible tool (honestly: much better than gprof. I will probably continue using it). But I am still kind of curious as to what's going on with gprof. sincerely, Brian
