Hi there, I have installed Linux Ubuntu and install GCC on top of it. I would like to make some modification on GCOV code especially for the GCC-Version with my own modified printed version. I try to make the changes in the gcov.c in /home/usr/local/gcc/gcc-4.2.1/gcov.c And after the changes made, when I query using gcov -v it doesnt show the modified version of the print that I made earlier on. Do you have any ideas what step did I miss out? Please help. Thanks. Regards, Lee
