Building on Unix with git, gcc and autotools
Home page for json-c:
https://github.com/json-c/json-c/wiki
Caution: do NOT use sources from svn.metaparadigm.com, they are old.
Prerequisites:
gcc (or another C compiler)
libtool
If you're not using a release tarball, you'll also need:
autoconf (autoreconf)
automake
Make sure you have a complete libtool install, including libtoolize
Github repo for json-c:
https://github.com/json-c/json-c
$ git clone https://github.com/json-c/json-c.git
$ cd json-c
$ sh autogen.sh
Then
$ ./configure
$ make
$ make install
To build and run the test programs run
$ make check
Linking to libjson-c
If your system has pkgconfig then you can just add this to your makefile
CFLAGS += $(shell pkg-config --cflags json-c)
LDFLAGS += $(shell pkg-config --libs json-c)
Without pkgconfig, you would do something like this:
JSON_C_DIR=/path/to/json_c/install
CFLAGS += -I$(JSON_C_DIR)/include/json-c
LDFLAGS+= -L$(JSON_C_DIR)/lib -ljson-c
