Change the name of gmon.out file when compiling with -pg

Question

Good morning

Is it possible to change the default name of the file gmon.out, which is created when the profile flag (-pg) is set when compiling with gcc, to, for example, [executable name].gmon.out?

I need this because I have more than one executables, which are located in the same directory, and have to run parallel.

thanks in advance.

In short, no. The profiling file created by running your program once it has been compiled with the -pg command is ALWAYS called gmon.out. However, once produced you can safely rename it to something else (for example foo.bar) and analyse it later using the command:

gprof test.exe foo.bar > analysis.txt
