## 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().

## Build defaults

## 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
#CJSON_CFLAGS =      -DUSE_POSIX_USELOCALE

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

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

## Solaris
#CJSON_CFLAGS =      -DUSE_POSIX_SETLOCALE -DUSE_INTERNAL_ISINF
