CJSON_VERSION = 1.0.4
LUA_VERSION =   5.1

## Available Lua CJSON specific workarounds
#
# To ensure JSON encoding/decoding works correctly for locales using
# comma decimal separators, Lua CJSON must be compiled with one of
# these options:
# USE_POSIX_USELOCALE: Linux, OSX. Thread safe. Recommended option.
# USE_POSIX_SETLOCALE: Works on all ANSI C platforms. May be used when
#                      thread-safety isn't required.
#
# USE_INTERNAL_ISINF: Workaround for Solaris platforms missing isinf().

## Common build defaults
PREFIX =            /usr/local
CFLAGS_EXTRA =      -DUSE_POSIX_SETLOCALE
LDFLAGS_EXTRA =     -shared

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

## Linux
CFLAGS_EXTRA =      -DUSE_POSIX_USELOCALE

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

## MacOSX (Macports)
#PREFIX =            /opt/local
#CFLAGS_EXTRA =      -DUSE_POSIX_USELOCALE
#LDFLAGS_EXTRA =     -bundle -undefined dynamic_lookup

## Solaris
#CFLAGS_EXTRA =      -DUSE_POSIX_SETLOCALE -DUSE_INTERNAL_ISINF
