michael@0 16
michael@0 17 The `gtest-config' script provides access to the necessary compile and linking
michael@0 18 flags to connect with Google C++ Testing Framework, both in a build prior to
michael@0 19 installation, and on the system proper after installation. The installation
michael@0 20 overrides may be issued in combination with any other queries, but will only
michael@0 21 affect installation queries if called on a built but not installed gtest. The
michael@0 22 installation queries may not be issued with any other types of queries, and
michael@0 23 only one installation query may be made at a time. The version queries and
michael@0 24 compiler flag queries may be combined as desired but not mixed. Different
michael@0 25 version queries are always combined with logical "and" semantics, and only the
michael@0 26 last of any particular query is used while all previous ones ignored. All
michael@0 27 versions must be specified as a sequence of numbers separated by periods.
michael@0 28 Compiler flag queries output the union of the sets of flags when combined.

michael@0 30 Examples:
michael@0 31 gtest-config --min-version=1.0 || echo "Insufficient Google Test version."
michael@0 32
michael@0 33 g++ $(gtest-config --cppflags --cxxflags) -o foo.o -c foo.cpp
michael@0 34 g++ $(gtest-config --ldflags --libs) -o foo foo.o
michael@0 35
michael@0 36 # When using a built but not installed Google Test:
michael@0 37 g++ $(../../my_gtest_build/scripts/gtest-config ...) ...
michael@0 38
michael@0 39 # When using an installed Google Test, but with installation overrides:
michael@0 40 export GTEST_PREFIX="/opt"
michael@0 41 g++ $(gtest-config --libdir="/opt/lib64" ...) ...

michael@0 44 --usage brief usage information
michael@0 45 --help display this help message
michael@0 46
michael@0 47 Installation Overrides:
michael@0 48 --prefix=<dir> overrides the installation prefix
michael@0 49 --exec-prefix=<dir> overrides the executable installation prefix
michael@0 50 --libdir=<dir> overrides the library installation prefix
michael@0 51 --includedir=<dir> overrides the header file installation prefix
michael@0 52
michael@0 53 Installation Queries:
michael@0 54 --prefix installation prefix
michael@0 55 --exec-prefix executable installation prefix
michael@0 56 --libdir library installation directory
michael@0 57 --includedir header file installation directory
michael@0 58 --version the version of the Google Test installation
michael@0 59
michael@0 60 Version Queries:
michael@0 61 --min-version=VERSION return 0 if the version is at least VERSION
michael@0 62 --exact-version=VERSION return 0 if the version is exactly VERSION
michael@0 63 --max-version=VERSION return 0 if the version is at most VERSION
michael@0 64
michael@0 65 Compilation Flag Queries:
michael@0 66 --cppflags compile flags specific to the C-like preprocessors
michael@0 67 --cxxflags compile flags appropriate for C++ programs
michael@0 68 --ldflags linker flags
michael@0 69 --libs libraries for linking
