| 17 The `gtest-config' script provides access to the necessary compile and linking | |
| 18 flags to connect with Google C++ Testing 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 gtest. 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 gtest-config --min-version=1.0 || echo "Insufficient Google Test version." | |
| 32 | |
| 33 g++ $(gtest-config --cppflags --cxxflags) -o foo.o -c foo.cpp | |
| 34 g++ $(gtest-config --ldflags --libs) -o foo foo.o | |
| 35 | |
| 36 # When using a built but not installed Google Test: | |
| 37 g++ $(../../my_gtest_build/scripts/gtest-config ...) ... | |
| 38 | |
| 39 # When using an installed Google Test, but with installation overrides: | |
| 40 export GTEST_PREFIX="/opt" | |
| 41 g++ $(gtest-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 Test 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 | |

| 75 # POSIX-compliant variable expansion to portably do all the work in the shell | |
| 76 # and avoid any dependency on a particular "sed" or "awk" implementation. | |
| 77 # Notable is that it will only ever compare the first 3 components of versions. | |
| 78 # Further components will be cleanly stripped off. All versions must be | |
| 79 # unadorned, so "v1.0" will *not* work. The minimum version must be in $1, and | |
| 80 # the max in $2. TODO(chandlerc@google.com): If this ever breaks, we should | |
| 81 # investigate expanding this via autom4te from AS_VERSION_COMPARE rather than | |
| 82 # continuing to maintain our own shell version. | |
