cocos2dx添加第三方库注意事项
前一段时间，使用cocos2dx2.0,在使用中文转码的时候，老是加载出问题。
Error1errorLNK2019:unresolvedexternalsymbol_libiconv_closereferencedinfunction"public:int__thiscallHelloWorld::GBKToUTF8(classstd::basic_string<char,structstd::char_traits<char>,classstd::allocator<char>>&,charconst*,charconst*)"(?GBKToUTF8@HelloWorld@@QAEHAAV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@PBD1@Z)F:\cocos2d\cocos2d2\HelloWorld\proj.win32\HelloWorldScene.objHelloWorld

，原因是在引用第三方库的时候，只写了头文件，#include"platform\third_party\win32\iconv\iconv.h"
只要在头文件附近加入
#pragmacomment(lib,"libiconv.lib")
即：
#if(CC_TARGET_PLATFORM==CC_PLATFORM_WIN32)
#include"platform\third_party\win32\iconv\iconv.h"
#pragmacomment(lib,"libiconv.lib")
#endif
可解决中文问题，下面附带函数：
intHelloWorld::GBKToUTF8(std::string&gbkStr,constchar*toCode,constchar*formCode)
{
iconv_ticonvH;iconvH=iconv_open(formCode,toCode);
if(iconvH==0)
{
return-1;
}
constchar*strChar=gbkStr.c_str();
constchar**pin=&strChar;
size_tstrLength=gbkStr.length();
char*outbuf=(char*)malloc(strLength*4);
char*pBuff=outbuf;
memset(outbuf,0,strLength*4);
size_toutLength=strLength*4;
if(-1==iconv(iconvH,pin,&strLength,&outbuf,&outLength))
{
iconv_close(iconvH);
return-1;
}
gbkStr=pBuff;
iconv_close(iconvH);
return0;
}
