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" ...) ... | |

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. | |
