##### Available defines for CJSON_CFLAGS #####
##
## USE_INTERNAL_ISINF:      Workaround for Solaris platforms missing isinf().
## DISABLE_CJSON_GLOBAL:    Do not store module is "cjson" global.
## DISABLE_INVALID_NUMBERS: Permanently disable invalid JSON numbers:
##                          NaN, Infinity, hex.
##
## Optional built-in number conversion uses the following defines:
## USE_INTERNAL_DTOA:       Use builtin strtod/dtoa for numeric conversions.
## IEEE_BIG_ENDIAN:         Required on big endian architectures.

##### Platform overrides #####
##
## Tweak one of the platform sections below to suit your situation.
##
## See http://lua-users.org/wiki/BuildingModules for further platform
## specific details.

## Linux

## FreeBSD
#LUA_INCLUDE_DIR =   $(PREFIX)/include/lua51

## MacOSX (Macports)
#PREFIX =            /opt/local
#CJSON_LDFLAGS =     -bundle -undefined dynamic_lookup

## Solaris
#CJSON_CFLAGS =      -fpic -DUSE_INTERNAL_ISINF

## Windows (MinGW)
#TARGET =            cjson.dll
#PREFIX =            /home/user/opt
#CJSON_CFLAGS =      -DDISABLE_INVALID_NUMBERS
#CJSON_LDFLAGS =     -shared -L$(PREFIX)/lib -llua51

##### Use built in number conversion (optional) #####

## Enable built in number conversion
#FPCONV_OBJS =       g_fmt.o dtoa.o
#CJSON_CFLAGS +=     -DUSE_INTERNAL_DTOA

## Compile built in number conversion for big endian architectures
#CJSON_CFLAGS +=     -DIEEE_BIG_ENDIAN

## Compile built in number conversion to support multi-threaded
## applications (recommended)
#CJSON_CFLAGS +=     -pthread -DMULTIPLE_THREADS
#CJSON_LDFLAGS +=    -pthread
