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

 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" ...) ...

 44  --usage                    brief usage information

 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

 74# This function bounds our version with a min and a max. It uses some clever
 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.
