COCOS2DX using Iconv transcoding (win32,ios,android)

First put the environment: Win7, NDK r8e, libiconv-1.14, Cygwin


A WIN32 environment configuration cocos2d-x from the Iconv Library with Win32, only need to be configured to use.
1 Introduction to header file properties, Configuration Properties->c/c++-> additional Include Directories:
$ (ProjectDir): \.. \.. \.. \cocos2dx\platform\third_party\win32\iconv


2 introduction of static libraries: Additional dependencies, input, connector, configuration properties, properties
Libiconv.lib


3 Defining a common transcoding function

#include "iconv.h" bool Iconv_convert (void *src, unsigned int src_len,char *src_charset, void *dest, unsigned int dest_len, Char *dest_charset) {const char *in;char *out,*dest_ptr;size_t in_left,out_left,mutant,converted;in_left=src_len;out _left=dest_len;in= (char *) src;out=dest_ptr= (char *) dest;iconv_t Oconv=iconv_open (Dest_charset,src_charset); oconv== (iconv_t) ( -1)) {Cclog ("error:unable to open Libiconv."); return false;} Mutant = Iconv (Oconv, &in, &in_left, &out, &out_left); Iconv_close (Oconv); if (mutant = = (size_t) (-1)) { Cclog ("error:unable to convert anything."); return false;} converted = Dest_len-out_left; Cclog ("To convert%u characters,%u mutanted,%u converted \ n", src_len,mutant,converted);d est_ptr[converted]= '; return true;}

4 Testing

void Converttest () {char instr[] = "Hello, this is a test program"; Char Outstr[1024];iconv_convert (&instr, sizeof (INSTR), "GBK", & Amp;outstr, sizeof (OUTSTR), "UTF-8"); Cclog ("SCR string:%s\n", inStr); Cclog ("DST string:%s\n", outstr);}

Output Result:
To convert characters, 0 mutanted, converted
SCR String:hello,????????????
DST String:hello, this is a test program

5 cross-Platform header file contains settings Win32 by the method above, set the header file containing the path and the dependent library, and then can include "iconv.h";
Bring your own libiconv.dylib on iOS, just include <iconv.h>.
Android needs to be compiled separately, next we will say;

#if Cc_target_platform = = cc_platform_win32#include "Iconv.h" #elif cc_target_platform = = Cc_platform_ios#include < iconv.h> #elif Cc_target_platform = = cc_platform_android#include "Icov/iconv.h" #endif

Second for Android compiled iconvandroid can not directly use the Cocos2d-x provided Iconv library, need to download a Linux environment has been compiled in the Iconv library.
1 Downloads Download libiconv-1.14.tar.gz package from official website, rename to Libiconv, unzip.
Official website: http://www.fsf.org/resources/


2 Compile open Cygwin, go to libiconv root directory, execute:

./configure--build=x86_64-pc-linux-gnu--host=arm-linux-eabi

Remember that this is not a./configure, otherwise there will be a lot of stdio.h in the back of the wrong.

Then execute:

Make

If you've done this before, you need to do it first:

Make clean

Then execute make

3 Copy header files copy the Icov folder under the Cocos2dx\platform\third_party\win32 to the root of the project, similar to class

4 Configuration 4.1 copy Libiconv to Project

Place the Libiconv in the cocos2d-x-2.1.4 root directory

4.2 Compiling the configuration

Create a new Android.mk file under the Libiconv directory with the following contents:

Local_path:= $ (call My-dir) include $ (clear_vars) Local_module: = iconv_staticlocal_module_filename: = Libiconvlocal_ CFLAGS: =   -wno-multichar   -dandroid   -dlibdir= "C"   -dbuilding_libiconv   -din_librarylocal_src_ FILES: =   libcharset/lib/localcharset.c   lib/iconv.c   lib/relocatable.clocal_c_includes + =   $ (local_ PATH)/include   $ (local_path)/libcharset   $ (local_path)/lib   $ (local_path)/libcharset/include   $ (Local_path)/srclib  include $ (build_static_library)

4.3 Modifying the Android.mka of a project add a search path we'll copy over the Iconv added header file in the search path
Local_c_includes + = $ (local_path)/. /.. /classes/iconv


b Add iconv_staticlocal_whole_static_libraries + = Iconv_static
Iconv_static is the value of Local_module in Android.mk in Iconv


C contains iconv sub-modules imported into our iconv defined in the ANDROID.MK
$ (call Import-module,libiconv)


Three common errors 1 langinfo.h:no such file or directory modifies the macro definitions in the Libiconv/libcharset/config.h files:
#define HAVE_LANGINFO_CODESET 1
For
#define HAVE_LANGINFO_CODESET 0
Another: Remember to remember not to use Baidu, pit dead, search not to want, do programmers, or think of ways to use Google it.


2 ' C ' undeclared modify the file/libcharset/lib/localcharset.c function get_charset_aliases (void),
search int C; Put to the beginning of the function body.
