Hi,

That helped a lot, thanks :-) I think I'm almost there. After running:

./virtualenv/bin/teuthology --archive /tmp/a1 /srv/3node_rgw.yaml

wget -O /tmp/build/tmp.tgz http://gitbuilder.ceph.com/ceph-tarball-precise-x86_64-gcov/sha1/$(cat /tmp/a1/ceph-sha1)/ceph.x86_64.tgz

echo ceph_build_output_dir: /tmp/build >> ~/.teuthology.yaml

./virtualenv/bin/teuthology-coverage -v --html-output /tmp/html --lcov-output /tmp/lcov --cov-tools-dir /srv/teuthology/coverage /tmp

I get

INFO:teuthology.coverage:initializing coverage data...
Retrieving source and .gcno files...
Initializing lcov files...
Deleting all .da files in /tmp/lcov/ceph/src and subdirectories

-rw-r--r-- 1 root root 41088 Jan 15 09:49 /tmp/lcov/ceph/src/test_libhadoopcephfs_build-AuthMethodList.gcno

I'm using

lcov: LCOV version 1.9

The only problem I can think of is that the machine I'm running lcov on is a Debian GNU/Linux Wheezy, trying to analyze coverage for binaries created for Ubuntu Precise. They are both amd64 but .gcno files may have dependencies to the toolchain.

Did you ever run into similar problems ?

Cheers
