Cocos2dx cross-compiled iconv Library

>

Cocos2dx provides third-party iconv for character conversion. When cross-compiling to Android, You need to introduce the iconv module, download iconv, decompress it to the cocos2d root directory, and write MK:

LOCAL_PATH := $(call my-dir)include $(CLEAR_VARS)LOCAL_ARM_MODE := armifeq ($(BUILD_WITH_NEON),1)LOCAL_ARM_NEON := trueendifLOCAL_MODULE := iconvLOCAL_CFLAGS +=     -DHAVE_CONFIG_H     -DBUILDING_LIBICONV     -DIN_LIBRARY      #  -DLIBICONV_PLUGLOCAL_C_INCLUDES +=     $(LOCAL_PATH)/include $(LOCAL_PATH)/libcharset $(LOCAL_PATH)/lib     $(LOCAL_PATH)/libcharset/include $(LOCAL_PATH)/srclibLOCAL_SRC_FILES :=     lib/iconv.c libcharset/lib/localcharset.c lib/relocatable.cLOCAL_STATIC_LIBRARIES += charsetinclude $(BUILD_STATIC_LIBRARY)include $(CLEAR_VARS)include $(call all-makefiles-under,$(LOCAL_PATH))

Compile Android. mk in JNI

Introduce the module and paste my mk
