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
