are you infusing or linking? – Sukkah

What files of gtest do you see within your project? Can you find the folder where gtest/gtest.h is in? – Quod

Answer 1

The source code of libgtest or libgtest_main libraries doesn't contain special functions which allow recognize their version (something like GetGTestVersion () or something else). Also header files doesn't have any defined identifiers (something like GTEST_VERSION or something else). So you can’t check version of Google C++ Testing Framework at runtime inside user code.

But maintainers provide as part of the framework special script scripts/gtest-conf which:

...
provides access to the necessary compile and linking
flags to connect with Google C++ Testing Framework, both in a build prior to
installation, and on the system proper after installation.
...

Among other things this script has several options which connected with version:

...
Installation Queries:
...
--version the version of the Google Test installation

Version Queries:
--min-version=VERSION return 0 if the version is at least VERSION
--exact-version=VERSION return 0 if the version is exactly VERSION
--max-version=VERSION return 0 if the version is at most VERSION
...

The script also contain usage example of it:

Examples:
gtest-config --min-version=1.0 || echo "Insufficient Google Test version."
...

It means that user can test version of the framework in build time using script gtest-config.

Note:

The script gtest-config get actual version of the framework during configuration through variables declared in configure.ac.

...
AC_INIT([Google C++ Testing Framework],
        [1.7.0],
        [[email protected]],
        [gtest])
...

And after calling autoconf the following identifiers inside configure file populated:

...
# Identity of this package.
PACKAGE_NAME='Google C++ Testing Framework'
PACKAGE_TARNAME='gtest'
PACKAGE_VERSION='1.7.0'
PACKAGE_STRING='Google C++ Testing Framework 1.7.0'
PACKAGE_BUGREPORT='[email protected]'
PACKAGE_URL=''
...
# Define the identity of the package.
PACKAGE='gtest'
VERSION='1.7.0'
...

As far the framework compiled with option AC_CONFIG_HEADERS this identifiers stored into file build-aux/config.h and availiable for user at compile time.

Answer 2

The file CHANGES, in the gtest home directory, contains a gtest version number.

Answer 3

If you have cloned the official repo you can check the latest Git commit inside Google Test's directory (using for example git log -n 1 or git rev-parse HEAD) and compare it with the list of released versions.

In my case, the commit hash is ec44c6c1675c25b9827aacd08c02433cccde7780, which turns out to correspond to release-1.8.0.
