|
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 |

# 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. |
