= Installing the Google C++ Testing Framework (gtest) globally =

'''Step 1:''' Change into the temporary directory, for example:

{{{
cd /tmp
}}}

'''Step 2:''' Download the latest (major) version from https://github.com/google/googletest/releases, for example:

{{{
wget https://github.com/google/googletest/archive/release-1.10.0.zip
}}}

'''Step 3:''' Unpack the archive, change to the corresponding directory and build the code from its source (this requires ''cmake'' which can be installed using your favorite package manager, for example: ''apt'' on Ubuntu or ''brew'' on Mac):

{{{
unzip release-1.10.0.zip
cd googletest-release-1.10.0/googletest
mkdir bld
cd bld
cmake ..
make
}}}

'''Step 4:''' Install the files, that is, copy them to the proper systems directories (you need to be root or have sudo rights for that):

{{{
cp -a -r ../include/gtest /usr/local/include/.
cp -a ./lib/*.a /usr/local/lib
}}}

'''(optional) Step 5:''' If the library is (still) not found by the compiler, you can run (as root or with sudo):

{{{
ldconfig
}}}

'''(optional) Step 6:''' Clean up:

{{{
cd /tmp
rm -rf release-1.10.0.zip googletest-release-1.10.0
}}}

= Troubleshooting =

 * ''Gtest 1.8.1'' is the last release supporting ''pre-C++11'' compilers. So if you get any errors when using Gtest > 1.8.1 in combination with a compiler that doesn't use the ''C++11'' standard per default, try to add the ''-std=c++11'' flag to your compile commands, for example:
 {{{
 g++ -std=c++11 -c ApproximateEulersNumber.cpp
 }}}
