lcov incompatible with GCC 9.x coverage data about lcov

[bayandin]

Hello, is there any plans for the next release with gcc-9 support?

[oberpar]

I'm currently reviewing the remaining open issues and pull requests for anything that should be included in the next release. Once I'm done with that I plan to release LCOV 1.15 (should be sometime next week).

[oberpar]

This should be fixed with commit 75fbae1.

LCOV support for the intermediate file format will (hopefully) be available before May.

[LesnyRumcajs]

I can confirm, this is working fine with gcc-9.1.1 minus the extra dependencies I had to install manually.

[oberpar]

Currently no new release is planned. LCOV GCC 9 support for Debian should be covered by a package upgrade to 1.14-2. See https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=924573

Can this be closed and replaced with a separate request to publish a release? master works well with GCC 9.3.0 per my testing

In case it may help, on my pet project I can use gcov to get the code coverage, but lcov fails. A really recent g++9 build is required, some stuff were fixed in gcov less than a week go and it uses C++20 feature only available on g++ at the moment.

if you have meson + conan + lcov + genhtml installed, and an extremely fresh build of g++9, it should be as easy to test as

git clone https://gitlab.com/robinmoussu/rollordie3.git && cd rollordie3
make
make coverage

I didn't tested to install it from another computer than mine however.

Feel free to ask me any additional data.

I can confirm that the problem exists with LCOV and GCC 9.0 .gcno files. This will be addressed via the LCOV intermediate file format support that I'm working on.

Great, may I ignore this as the intermediate support in LCOV will appear before GCC 9.1 is released (May 2019) ?

In my tests, I can confirm this issue affects the following versions:

• 9.1, (See: https://gitlab.com/proot/proot/-/jobs/199163599).
• 8.3, (See: https://gitlab.com/proot/proot/-/jobs/209815447).

Tested on official docker images, (See: https://hub.docker.com/_/gcc), for each version, respectfully.

@oberpar are there any issues blocking this that require assistance?

[rockdaboot]

Do you already plan a new release ? Debian (unstable) just switched to gcc 9.2.1 ... :-)

[rockdaboot]

That bug has been opened in March. I left a comment about gcc 9 on Friday - Saturday they had it fixed :-)

openSUSE Tumbleweed also offers the package that includes the patch:

lcov-1.15+git.20190524.75fbae1.tar.xz

Hello, is there any plans for the next release with gcc-9 support?

I too would like to see a new release; at least a tag in here. The only thing missing seems to list the additional new dependencies in the installation section of the README.

[lipnitsk]

@oberpar given how stable this project is (few changes in the last year) and the amount of exposure this issue has received in various distros (I use Arch), isn't it time to tag a new release?

[oberpar]

Closing this issue since the original problem has been addressed.
