| |
| The `gtest-config' script provides access to the necessary compile and linking |
| flags to connect with Google C++ Testing Framework, both in a build prior to |
| installation, and on the system proper after installation. 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: |

| |
| Installation Overrides: |
| --prefix=<dir> overrides the installation prefix |
| --exec-prefix=<dir> overrides the executable installation prefix |
| --libdir=<dir> overrides the library installation prefix |
| --includedir=<dir> 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 |

| # 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. TODO(chandlerc@google.com): If this ever breaks, we should |
| # investigate expanding this via autom4te from AS_VERSION_COMPARE rather than |
| # continuing to maintain our own shell version. |
