Description of problem:
When C source files are compiled with ccache and coverage flags enabled, (-ftest-coverage and -fprofile-arcs), .gcno files are generated, but in ~/.ccache. Those also should move to build directories as .o files does.
There are 2 options, IMHO to solve this kind of problem;
1: Disable ccache: Unfortunately, ccache package installs a ccache.sh file in /etc/profile.d wich force to use it. So it could be posible to clear this file from ccache package.
2: Implement funtionality to move .gcno files to builddir.
Option 2 is an enhacement, so I thought that fastest option to solve this issue is op 1.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install ccache-2.4-3.
2. compile elfutils-115 (from rawhide) witn --enable-gcov
3. run /tests/coverage.sh
Doesn't setting CCACHE_DISABLE in the environment satisfy your option 1? See
the ccache man page for more info.
It's been some time, so I'm assuming comment 1 was a sufficient solution. Feel
free to reopen if not.
