I thought that gcov-tool is part of gcc standard package, which is true for Ubuntu. But unfortunately it's not true for RHEL.

I didn't succeed to find RHEL package name to install gcov-tool. Does anybody know it?

What should I write in my terminal to get gcov-tool installed (with exactly same version, as gcc & other dev-tools)?

I've tried to install all Development Tools (yum group install "Development Tools"), it installed successfully, but gcov-tool wasn't installed.

There is next list of RHEL versions where I need gcov-tool:
rhel6.6-x86_64
rhel6.7-x86_64
rhel6.8-x86_64
rhel6.9-x86_64
rhel7.0-x86_64
rhel7.1-x86_64
rhel7.2-x86_64
rhel7.3-x86_64
rhel7.3-x86_64
rhel7.4-x86_64
rhel7.5-x86_64
rhel7.6-x86_64

You need to install one of the devtoolset packages via yum. I recommend devtoolset-8 as it's the latest and it's what you'll have in Ubuntu. devtoolset-6 and devtoolset-7 also have it if you prefer one of those.

First, make sure that the rhel-server-rhscl-7-rpms repos is enabled. You can just enable them all:

subscription-manager repos --enable rhel*

After that, install devtoolset-8:

yum install devtoolset-8*

Then, add the gcc from devtoolset to your environment:

scl enable devtoolset-8 bash

You can then see gcov-tool available:

which gcov-tool

It will be located in /opt/rh/devtoolset-8/root/usr/bin.

Another way to get gcov-tool is to build gcc from source but that's far more complicated

It may happen that people who will search for this solution in fact need a way to get one report from many sources.

And they meet next problems:

• among different operating systems it needs to perform different steps to achieve tools


• *.gcda from different OS or compiler versions sometimes can't be merged


• machine where you run merge may not be same machine as one where you compiled your binary (which will produce incompatible gcda's), even may not have same OS

So, general way to achieve the goal was just to convert *.gcda to any markup text format (such as html or xml) and then use one of existing tool to merge those reports, not matter where and on which OS.

This doesn't answer the question above, but this idea may be helpful for people who once meet question above.

PROS: you just forget about binary differences and OS relative tools.

CONS: size of set of *.gcda is 20-50 times less than size of it's XML representation.
