The json-c implements a reference counting object model that allows you to easily construct JSON objects in C, output them as JSON formatted strings and parse JSON formatted strings back into the C representation of JSON objects.

Doxygen-1.18.0 and Graphviz-15.1.1 (for dot tool)
Install json-c by running the following commands:
mkdir build &&
cd build &&
cmake -D CMAKE_INSTALL_PREFIX=/usr \
-D CMAKE_BUILD_TYPE=Release \
-D BUILD_STATIC_LIBS=OFF \
.. &&
make
If you have installed Doxygen-1.18.0 and Graphviz-15.1.1, you can build the documentation by running the following command:
doxygen doc/Doxyfile
To test the results, issue: make USE_VALGRIND=0 test. Note that testing with the latest valgrind causes several test failures.
Now, as the root user:
make install
If you built the documentation, install it by running the following
commands as the root user:
install -d -vm755 /usr/share/doc/json-c-0.19 && install -v -m644 doc/html/* /usr/share/doc/json-c-0.19
-D
CMAKE_BUILD_TYPE=Release: This switch is used to apply
a higher level of compiler optimizations.
