用NDK编译lua库

Android.mk是这样的

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := lua
LOCAL_SRC_FILES := lua.cpp

MY_FILES := $(wildcard $(LOCAL_PATH)/lua/*.c)
MY_FILES := $(MY_FILES:$(LOCAL_PATH)/%=%)

LOCAL_SRC_FILES += $(MY_FILES)

# includes
LOCAL_C_INCLUDES := $(LOCAL_PATH)
LOCAL_C_INCLUDES += $(LOCAL_PATH)/lua/

include $(BUILD_SHARED_LIBRARY)

lua的源码放在jni/lua目录下，删除lua.c和luac.c

执行ndk-build，会报错：

llex.c:237:18: error: 'struct lconv' has no member named 'decimal_point'

查了下，是定义小数点字符的，把这段注释掉，直接定义算了：

// #if !defined(l_getlocaledecpoint)
// #define l_getlocaledecpoint()     (localeconv()->decimal_point[0])
// #endif

#define l_getlocaledecpoint() '.'

还有个liolib.c也改下，这样就编译成功了。

我用的是lua5.3。

等会学习下lua
