[Valgrind-users] Cachegrind linking issue

[Michaël K. <mic...@li...>]

Hello,
One of my fellow students and me wanted to use valgrind/cachegrind for some research. For our research, we wanted to modifythe indirect branch prediction technique that was used in cachegrind (cg_branchpred.c). After modifying some of the code , we weren't able to include the math.h library for example. We've tried modifying the Makefile in every single way (-lm flag) to try and solve this issue, but we simply don't find a solution. 
Is it possible to help us and tell us what to do? 
Yours sincerely
Michael
