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.

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" ...) ...
42
43 Help:
44 --usage brief usage information
45 --help display this help message
46
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

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.
