cocos2dx使用iconv 多国语言要用到开源字符转换

1.下载

在windows上用iconv.dll，在IOS上系统有提供这个库，导入就可以，在android上要自己去下一个。

http://ftp.gnu.org/pub/gnu/libiconv/

这个是官网地址，目前iconv最新版本是1.14,2011.8.7版本的，大小4.8M

官方地址：

http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.14.tar.gz

2.下载完毕，解压放到Engine目录下,改名为iconv,和cocos2dx，CocosDenshion，extensions等同目录

3.在iconv目录下增加Android.mk文件，写入

LOCAL_PATH:= $(call my-dir)

#libiconv.so

include $(CLEAR_VARS)

LOCAL_MODULE := iconv_static

LOCAL_MODULE_FILENAME := libiconv

LOCAL_CFLAGS := \
-Wno-multichar \
-DAndroid \
-DLIBDIR="c" \
-DBUILDING_LIBICONV \
-DIN_LIBRARY

LOCAL_SRC_FILES := \
libcharset/lib/localcharset.c \
lib/iconv.c \
lib/relocatable.c

LOCAL_C_INCLUDES += \
$(LOCAL_PATH)/include \
$(LOCAL_PATH)/libcharset \
$(LOCAL_PATH)/lib \
$(LOCAL_PATH)/libcharset/include \
$(LOCAL_PATH)/srclib

include $(BUILD_STATIC_LIBRARY)

4. 在工程的Android.mk里修改，加入这个lib和include目录（下面的路径要根据项目实际情况修改）

LOCAL_C_INCLUDES := $(LOCAL_PATH) \
：

$(LOCAL_PATH)/../../../../../Engine/iconv/include \

$(LOCAL_PATH)/../../../../../Engine/iconv/libcharset \

$(LOCAL_PATH)/../../../../../Engine/iconv/lib \

$(LOCAL_PATH)/../../../../../Engine/iconv/libcharset/include \

$(LOCAL_PATH)/../../../../../Engine/iconv/srclib \

$(LOCAL_PATH)/../../../../../Engine/iconv \

#================================

LOCAL_WHOLE_STATIC_LIBRARIES += cocos2dx_static

LOCAL_WHOLE_STATIC_LIBRARIES += cocosdenshion_static

LOCAL_WHOLE_STATIC_LIBRARIES += box2d_static

LOCAL_WHOLE_STATIC_LIBRARIES += chipmunk_static

LOCAL_WHOLE_STATIC_LIBRARIES += cocos_extension_static
LOCAL_WHOLE_STATIC_LIBRARIES += iconv_static

LOCAL_CFLAGS := $(MYCOMPILE_FLAG)

include $(BUILD_SHARED_LIBRARY)

$(call import-module,cocos2dx)

$(call import-module,cocos2dx/platform/third_party/android/prebuilt/libcurl)

$(call import-module,CocosDenshion/android)

$(call import-module,extensions)

$(call import-module,external/Box2D)

$(call import-module,external/chipmunk)
$(call import-module,iconv)

5。网上很多教程都说到这里，但实际上，如果这个时候进行编译，问题还一大堆。

1）iconv.h不存在，在ivonv/include/有 iconv.h.in, iconv.h.build.in，就是没看到iconv.h

把iconv.h.in改名成iconv.h，发现编译很多错误

主要错误是类型不匹配，还有很多@符号。

因此需要进行修改。主要改法是不存在的改成存在的，@符号去掉

下面是我自己改完之后的iconv.h文件。编译OK.颜色的是修改的(本来完整的，但是发出来后注释和include好像被新浪给吃没了)
