From 4780e5326f3ec858252f0ef3b8bb779dbf37b4fe Mon Sep 17 00:00:00 2001 From: Sergio Ahumada Date: Sat, 3 Aug 2013 00:05:05 +0200 Subject: Integrate gcov support into Qt build system. To instrument a Qt application or library with the gcov coverage tool, do `CONFIG+=gcov' in the application .pro file. To instrument Qt itself with gcov, use the `-gcov' configure option.
