| 17 The `gmock-config' script provides access to the necessary compile and linking |
| 18 flags to connect with Google C++ Mocking Framework, both in a build prior to |
| 19 installation, and on the system proper after installation. The installation |
| 20 overrides may be issued in combination with any other queries, but will only |
| 21 affect installation queries if called on a built but not installed gmock. The |
| 22 installation queries may not be issued with any other types of queries, and |
| 23 only one installation query may be made at a time. The version queries and |
| 24 compiler flag queries may be combined as desired but not mixed. Different |
| 25 version queries are always combined with logical "and" semantics, and only the |
| 26 last of any particular query is used while all previous ones ignored. All |
| 27 versions must be specified as a sequence of numbers separated by periods. |
| 28 Compiler flag queries output the union of the sets of flags when combined. |
| 29 |
| 30 Examples: |
| 31 gmock-config --min-version=1.0 || echo "Insufficient Google Mock version." |
| 32 |
| 33 g++ $(gmock-config --cppflags --cxxflags) -o foo.o -c foo.cpp |
| 34 g++ $(gmock-config --ldflags --libs) -o foo foo.o |
| 35 |
| 36 # When using a built but not installed Google Mock: |
| 37 g++ $(../../my_gmock_build/scripts/gmock-config ...) ... |
| 38 |
| 39 # When using an installed Google Mock, but with installation overrides: |
| 40 export GMOCK_PREFIX="/opt" |
| 41 g++ $(gmock-config --libdir="/opt/lib64" ...) ... |

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