"""Builds the Google Test (gtest) lib. This has been tested on Windows,
Linux, Mac OS X, and Cygwin. The compilation settings from your project
will be used, with some specific flags required for gtest added.
You should be able to call this file from more or less any SConscript
file.
You can optionally set a variable on the construction environment to
have the unit test executables copied to your output directory. The
variable should be env['EXE_OUTPUT'].
Another optional variable is env['LIB_OUTPUT']. If set, the generated
libraries are copied to the folder indicated by the variable.
If you place the gtest sources within your own project's source
directory, you should be able to call this SConscript file simply as
follows:
# -- cut here --
# Build gtest library; first tell it where to copy executables.
env['EXE_OUTPUT'] = '#/mybuilddir/mybuildmode' # example, optional
env['LIB_OUTPUT'] = '#/mybuilddir/mybuildmode/lib'
env.SConscript('whateverpath/gtest/scons/SConscript')
# -- cut here --
If on the other hand you place the gtest sources in a directory
outside of your project's source tree, you would use a snippet similar
to the following:
# -- cut here --
# The following assumes that $BUILD_DIR refers to the root of the
# directory for your current build mode, e.g. "#/mybuilddir/mybuildmode"
# Build gtest library; as it is outside of our source root, we need to
# tell SCons that the directory it will refer to as
# e.g. $BUILD_DIR/gtest is actually on disk in original form as
# ../../gtest (relative to your project root directory). Recall that
# SCons by default copies all source files into the build directory
# before building.
gtest_dir = env.Dir('$BUILD_DIR/gtest')
# Modify this part to point to gtest relative to the current
# SConscript or SConstruct file's directory. The ../.. path would
# be different per project, to locate the base directory for gtest.
gtest_dir.addRepository(env.Dir('../../gtest'))
# Tell the gtest SCons file where to copy executables.
env['EXE_OUTPUT'] = '$BUILD_DIR' # example, optional
# Call the gtest SConscript to build gtest.lib and unit tests. The
# location of the library should end up as
# '$BUILD_DIR/gtest/scons/gtest.lib'
env.SConscript(env.File('scons/SConscript', gtest_dir))
# -- cut here --
