It uses +those values to create a `Makefile' in each directory of the package. +It may also create one or more `.h' files containing system-dependent +definitions. Finally, it creates a shell script `config.status' that +you can run in the future to recreate the current configuration, and a +file `config.log' containing compiler output (useful mainly for +debugging `configure'). + + It can also use an optional file (typically called `config.cache' +and enabled with `--cache-file=config.cache' or simply `-C') that saves +the results of its tests to speed up reconfiguring. (Caching is +disabled by default to prevent problems with accidental use of stale +cache files.) + + If you need to do unusual things to compile the package, please try +to figure out how `configure' could check whether to do them, and mail +diffs or instructions to the address given in the `README' so they can +be considered for the next release. If you are using the cache, and at +some point `config.cache' contains results you don't want to keep, you +may remove or edit it. + + The file `configure.ac' (or `configure.in') is used to create +`configure' by a program called `autoconf'. You only need +`configure.ac' if you want to change it or regenerate `configure' using +a newer version of `autoconf'. + +The simplest way to compile this package is: + + 1. `cd' to the directory containing the package's source code and type + `./configure' to configure the package for your system. If you're + using `csh' on an old version of System V, you might need to type + `sh ./configure' instead to prevent `csh' from trying to execute + `configure' itself. + + Running `configure' takes awhile. While running, it prints some + messages telling which features it is checking for. + + 2. Type `make' to compile the package. + + 3. Optionally, type `make check' to run any self-tests that come with + the package. + + 4. Type `make install' to install the programs and any data files and + documentation. + + 5. You can remove the program binaries and object files from the + source code directory by typing `make clean'. To also remove the + files that `configure' created (so you can compile the package for + a different kind of computer), type `make distclean'. There is + also a `make maintainer-clean' target, but that is intended mainly + for the package's developers. If you use it, you may have to get + all sorts of other programs in order to regenerate files that came + with the distribution. + +Compilers and Options +===================== + + Some systems require unusual options for compilation or linking that +the `configure' script does not know about. Run `./configure --help' +for details on some of the pertinent environment variables. + + You can give `configure' initial values for configuration parameters +by setting variables in the command line or in the environment. Here +is an example: + + ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix + + *Note Defining Variables::, for more details. + +Compiling For Multiple Architectures +==================================== + + You can compile the package for more than one kind of computer at the +same time, by placing the object files for each architecture in their +own directory. To do this, you must use a version of `make' that +supports the `VPATH' variable, such as GNU `make'. `cd' to the +directory where you want the object files and executables to go and run +the `configure' script. `configure' automatically checks for the +source code in the directory that `configure' is in and in `..'. + + If you have to use a `make' that does not support the `VPATH' +variable, you have to compile the package for one architecture at a +time in the source code directory. After you have installed the +package for one architecture, use `make distclean' before reconfiguring +for another architecture. + +Installation Names +================== + + By default, `make install' will install the package's files in +`/usr/local/bin', `/usr/local/man', etc. You can specify an +installation prefix other than `/usr/local' by giving `configure' the +option `--prefix=PATH'. + + You can specify separate installation prefixes for +architecture-specific files and architecture-independent files. If you +give `configure' the option `--exec-prefix=PATH', the package will use +PATH as the prefix for installing programs and libraries. +Documentation and other data files will still use the regular prefix. + + In addition, if you use an unusual directory layout you can give +options like `--bindir=PATH' to specify different values for particular +kinds of files. Run `configure --help' for a list of the directories +you can set and what kinds of files go in them. + + If the package supports it, you can cause programs to be installed +with an extra prefix or suffix on their names by giving `configure' the +option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. + +Optional Features +================= + + Some packages pay attention to `--enable-FEATURE' options to +`configure', where FEATURE indicates an optional part of the package. +They may also pay attention to `--with-PACKAGE' options, where PACKAGE +is something like `gnu-as' or `x' (for the X Window System). The +`README' should mention any `--enable-' and `--with-' options that the +package recognizes. + + For packages that use the X Window System, `configure' can usually +find the X include and library files automatically, but if it doesn't, +you can use the `configure' options `--x-includes=DIR' and +`--x-libraries=DIR' to specify their locations. + +Specifying the System Type +========================== + + There may be some features `configure' cannot figure out +automatically, but needs to determine by the type of machine the package +will run on. Usually, assuming the package is built to be run on the +_same_ architectures, `configure' can figure that out, but if it prints +a message saying it cannot guess the machine type, give it the +`--build=TYPE' option. TYPE can either be a short name for the system +type, such as `sun4', or a canonical name which has the form: + + CPU-COMPANY-SYSTEM + +where SYSTEM can have one of these forms: + + OS KERNEL-OS + + See the file `config.sub' for the possible values of each field. If +`config.sub' isn't included in this package, then this package doesn't +need to know the machine type. + + If you are _building_ compiler tools for cross-compiling, you should +use the `--target=TYPE' option to select the type of system they will +produce code for. + + If you want to _use_ a cross compiler, that generates code for a +platform different from the build platform, you should specify the +"host" platform (i.e., that on which the generated programs will +eventually be run) with `--host=TYPE'. + +Sharing Defaults +================ + + If you want to set default values for `configure' scripts to share, +you can create a site shell script called `config.site' that gives +default values for variables like `CC', `cache_file', and `prefix'. +`configure' looks for `PREFIX/share/config.site' if it exists, then +`PREFIX/etc/config.site' if it exists. Or, you can set the +`CONFIG_SITE' environment variable to the location of the site script. +A warning: not all `configure' scripts look for a site script. + +Defining Variables +================== + + Variables not defined in a site shell script can be set in the +environment passed to `configure'. However, some packages may run +configure again during the build, and the customized values of these +variables may be lost. In order to avoid this problem, you should set +them in the `configure' command line, using `VAR=value'. For example: + + ./configure CC=/usr/local2/bin/gcc + +will cause the specified gcc to be used as the C compiler (unless it is +overridden in the site shell script). + +`configure' Invocation +====================== + + `configure' recognizes the following options to control how it +operates. + +`--help' +`-h' + Print a summary of the options to `configure', and exit. + +`--version' +`-V' + Print the version of Autoconf used to generate the `configure' + script, and exit. + +`--cache-file=FILE' + Enable the cache: use and save the results of the tests in FILE, + traditionally `config.cache'. FILE defaults to `/dev/null' to + disable caching. + +`--config-cache' +`-C' + Alias for `--cache-file=config.cache'. + +`--quiet' +`--silent' +`-q' + Do not print messages saying which checks are being made. To + suppress all normal output, redirect it to `/dev/null' (any error + messages will still be shown). + +`--srcdir=DIR' + Look for the package's source code in directory DIR. Usually + `configure' can determine that directory automatically. + +`configure' also accepts some other, not widely useful, options. Run +`configure --help' for more details. + diff --git a/Makefile.am b/Makefile.am new file mode 100644 index 0000000..bf5d7ce --- /dev/null +++ b/Makefile.am @@ -0,0 +1,43 @@ +AM_CFLAGS = -Wall -Wwrite-strings -Werror -std=gnu99 -D_GNU_SOURCE -D_REENTRANT + +EXTRA_DIST = doc + +lib_LTLIBRARIES = libjson.la + +pkgconfigdir = $(libdir)/pkgconfig +pkgconfig_DATA = json.pc + +libjsonincludedir = $(includedir)/json +libjsoninclude_HEADERS = \ + json.h \ + bits.h \ + debug.h \ + linkhash.h \ + arraylist.h \ + printbuf.h \ + json_util.h \ + json_object.h \ + json_object_private.h \ + json_tokener.h + +libjson_la_LDFLAGS = -version-info 0:1:0 + +libjson_la_SOURCES = \ + arraylist.c \ + debug.c \ + json_object.c \ + json_tokener.c \ + json_util.c \ + linkhash.c \ + printbuf.c + +check_PROGRAMS = test1 test2 test3 + +test1_SOURCES = test1.c +test1_LDADD = $(lib_LTLIBRARIES) + +test2_SOURCES = test2.c +test2_LDADD = $(lib_LTLIBRARIES) + +test3_SOURCES = test3.c +test3_LDADD = $(lib_LTLIBRARIES) diff --git a/NEWS b/NEWS new file mode 100644 index 0000000..41e843b --- /dev/null +++ b/NEWS @@ -0,0 +1 @@ +News diff --git a/README b/README new file mode 100644 index 0000000..beeba53 --- /dev/null +++ b/README @@ -0,0 +1,20 @@ +Building on Unix with gcc and autotools + +If checking out from CVS: + + sh autogen.sh + +Then configure, make, make install + + +Test programs + +To build the test programs run 'make check' + + +Linking to libjson + +If your system has pkgconfig then you can just add this to your makefile + +CFLAGS += $(shell pkg-config --cflags json) +LDFLAGS += $(shell pkg-config --libs json) diff --git a/README-WIN32.html b/README-WIN32.html new file mode 100644 index 0000000..678fc9d --- /dev/null +++ b/README-WIN32.html @@ -0,0 +1,57 @@ + + + + JSON-C - A JSON implementation in C - Win32 specific notes + + + +

Windows specific notes for JSON-C

+

Please send Win32 bug reports to christopher.watford@gmail.com

+

Win32 Specific Changes:

+
    +
  • + Various functions have been redefined to their Win32 version (i.e. open + on win32 is _open)
    • +
  • + Implemented missing functions from MS's libc (i.e. vasprintf and strndup)
    • +
  • + Added code to allow Win64 support without integer resizing issues, this + probably makes it much nicer on 64bit machines everywhere (i.e. using ptrdiff_t + for pointer math)
    • +
+

Porting Changelog:

+
+
printbuf.c - C. Watford (christopher.watford@gmail.com)
+
+ Added a Win32/Win64 compliant implementation of vasprintf
+
debug.c - C. Watford (christopher.watford@gmail.com)
+
+ Removed usage of vsyslog on Win32/Win64 systems, needs to be handled + by a configure script
+
json_object.c - C. Watford (christopher.watford@gmail.com)
+
+ Added scope operator to wrap usage of json_object_object_foreach, this needs to be + rethought to be more ANSI C friendly
+
json_object.h - C. Watford (christopher.watford@gmail.com)
+
+ Added Microsoft C friendly version of json_object_object_foreach
+
json_tokener.c - C. Watford (christopher.watford@gmail.com)
+
+ Added a Win32/Win64 compliant implementation of strndup
+
json_util.c - C. Watford (christopher.watford@gmail.com)
+
+ Added cast and mask to suffice size_t v. unsigned int + conversion correctness

JSON-C - A JSON implementation in C

+

Latest release: json-c-0.9.tar.gz

+

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.

+

Minimal documentation exists here, + Although you are probably better reading the example code in test1.c.

+

To setup JSON-C to build on your system please run configure before + compiling. If you are on Win32 and are not using the VS project file, be sure + to rename config.h.win32 to config.h before building.

+

Win32 specific notes can be found here.
