Can't built libleak on CentOS 7 like system #17

I tried to build libleak on a CentOS like system, but I can't figure out what package is supposed to provide the header backtrace.h I really appreciate any help to be able to use libleak on CentOS.

libbacktrace is built-in with GCC at my Ubuntu 16.04. It locates at /usr/lib/gcc/x86_64-linux-gnu/5/libbacktrace.a.

You can get and build it from https://github.com/ianlancetaylor/libbacktrace if your system does not have it.

Thanks for the help. Building and using libbacktrace as you pointed out, allowed me to build libleak on my system.

I tried to ran libleak on my code and I got an ABORT signal. I figured out I have to increase this array to be able to use libleak to test my code. Is it safe to increase that array? Or would this affect performances?

Just increase it. It just costs more memory, but not affects performance.
