Hi all! Using Centos-7, I'm trying to build a C-language app using -fsanitize=address, or -fsanitize=thread. If I compile (and link) with -fsanitize=address when it tries to link it complains of missing libasan.so.x.x.x. Similarly compiling with -fsanitize=thread, it complains of a missing libtsan.so.x.x.x. I can't figure out where one is supposed to find those libraries. they don't appear to be part of the GCC packages, and doing yum whatprovides */libasan.so or yum whatprovides */libtsan.so turns up nothing. Clues appreciated, thanks in advance! Fred -- ---- Fred Smith -- fredex at fcshome.stoneham.ma.us ----------------------------- The Lord is like a strong tower.
