The installation overrides may be issued in combination with any other queries, but will only affect installation queries if called on a built but not installed gtest. The installation queries may not be issued with any other types of queries, and only one installation query may be made at a time. The version queries and compiler flag queries may be combined as desired but not mixed. Different version queries are always combined with logical "and" semantics, and only the last of any particular query is used while all previous ones ignored. All versions must be specified as a sequence of numbers separated by periods. Compiler flag queries output the union of the sets of flags when combined. Examples: gtest-config --min-version=1.0 || echo "Insufficient Google Test version." g++ $(gtest-config --cppflags --cxxflags) -o foo.o -c foo.cpp g++ $(gtest-config --ldflags --libs) -o foo foo.o # When using a built but not installed Google Test: g++ $(../../my_gtest_build/scripts/gtest-config ...) ... # When using an installed Google Test, but with installation overrides: export GTEST_PREFIX="/opt" g++ $(gtest-config --libdir="/opt/lib64" ...) ... Help: --usage brief usage information --help display this help message Installation Overrides: --prefix= overrides the installation prefix --exec-prefix= overrides the executable installation prefix --libdir= overrides the library installation prefix --includedir= overrides the header file installation prefix Installation Queries: --prefix installation prefix --exec-prefix executable installation prefix --libdir library installation directory --includedir header file installation directory --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 Compilation Flag Queries: --cppflags compile flags specific to the C-like preprocessors --cxxflags compile flags appropriate for C++ programs --ldflags linker flags --libs libraries for linking EOF } # This function bounds our version with a min and a max. It uses some clever # POSIX-compliant variable expansion to portably do all the work in the shell # and avoid any dependency on a particular "sed" or "awk" implementation. # Notable is that it will only ever compare the first 3 components of versions. # Further components will be cleanly stripped off. All versions must be # unadorned, so "v1.0" will *not* work. The minimum version must be in $1, and # the max in $2.
