== Installing gtest manually - deprecated but more detailed ==

'''Step 1:''' Download the latest (major) version from http://code.google.com/p/googletest, for example:

{{{
wget http://googletest.googlecode.com/files/gtest-1.7.0.zip
}}}

{{{
curl -o gtest-1.7.0.zip http://googletest.googlecode.com/files/gtest-1.7.0.zip
}}}

'''Step 2:''' Unpack the archive, change to the corresponding directory and build the code from its source:

{{{
unzip gtest-1.7.0.zip
cd gtest-1.7.0
./configure
make
}}}

Check in the output of ''./configure'', whether the g++ compiler was found. If not, install it (e.g., with ''sudo apt-get install g++''), and repeat the ''./configure''.

'''Step 3:''' Install the files, that is, copy them to the proper systems directories (you need to be root or have sudo rights for that):

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

'''Step 4:''' Check that the following files exist:

{{{
/usr/local/include/gtest/gtest.h
/usr/local/lib/libgtest.a
/usr/local/lib/libgtest.so
}}}

'''(optional) Step 5:''' If the library is (still) not found by the compiler, you can run:
{{{
sudo ldconfig
}}}
