 *  支持 XML 进行界面布局，主题和样式表技术，轻松实现界面换肤；
 *  支持视网膜高清分辨率技术，配合高清屏可呈现平滑细腻的图形和文字。

上面简单介绍了一下ZLG的GUI，下面开始填坑。

填坑之前先说一下为啥给自己挖坑。在windows下搞C语言设计开发，可能更多人会选择VS，但是编译AWTK需要比较高版本的VS，这对我来说体验不是很好，VS的安装包体积实在是太大了，启动又慢，我只需要用到编译代码这一个基础功能，显然VS不是理想的选择。

后来在AWTK的帮助文档里看到，AWTK可以使用MinGW作为编译工具，而且官方提供了使用方法，遂决定试用一下。实践结果告诉我，官方的使用方法根本编译不过去，这才有了填坑记录。

系统：WIN7 X64 旗舰版

硬件：i5 M560+3G内存+64G固态

软件：AWTK-Designer-x64-0.1.3-Preview-Setup      python-3.8.3-amd64     awtk-scons-mingw

1、ZLG官方提供了一个GUI界面设计编辑器，需要注册使用，下载地址：[https://awtk.zlg.cn/][https_awtk.zlg.cn]

点击 登录 按钮下方的 客户端下载 即可。下载得到的是一个64位的安装程序，只能在64位系统下使用，下面介绍安装过程。

双击AWTK-Designer安装包进行安装，默认安装到C盘。

AWTK-Designer安装完成后，可以在SDK文件夹下找到AWTK的全部源码，无需另外下载，但有可能不是最新的版本，如果需要最新的源码，需要到主源码仓库：https://github.com/zlgopen/awtk  进行更新。

2、从python官网下载64位的安装包，地址：[https://www.python.org/downloads/windows/][https_www.python.org_downloads_windows]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3JlbnBlbmcwMDk2NzI_size_16_color_FFFFFF_t_70 1][]

双击安装包，在 Add Python 3.8 to PATH 前打勾，然后选择自定义安装。

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3JlbnBlbmcwMDk2NzI_size_16_color_FFFFFF_t_70 2][]

修改安装路径

其他选项保持默认。

下载scons，地址：[https://scons.org/pages/download.html][https_scons.org_pages_download.html]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3JlbnBlbmcwMDk2NzI_size_16_color_FFFFFF_t_70 4][]

解压到任意目录，打开CMD，进入scons目录，输入

python setup.py install

进行安装。

3、AWTK提供了MinGW，地址：[https://github.com/zlgopen/awtk-scons-mingw][https_github.com_zlgopen_awtk-scons-mingw]

将MinGW文件夹解压到C盘，然后添加环境变量。

CMD窗口输入

gcc -v

可以看到，ZLG提供的MinGW是32位的。

4、目前看，工具是备齐了，编译试试看，有不足的地方再补充。

先来看看awtk-scons-mingw的官方说明

我们按照官方指示，用记事本打开C:\\AWTK\\SDK\\awtk\\awtk\_config.py，找到

NATIVE_WINDOW='sdl'
    TOOLS_NAME = ''
    # TOOLS_NAME = 'mingw'

修改为

NATIVE_WINDOW='sdl'
    TOOLS_NAME = ''
    TOOLS_NAME = 'mingw'

在C:\\AWTK\\SDK\\awtk目录下打开CMD，输入scons，执行编译。随着CPU风扇一阵狂转，命令停在了下面这个位置

很明显，在C:\\AWTK\\SDK\\awtk\\src\\platforms\\pc\\fs\_os.c的第189、296、327、405行出现了

> error: storage size of 'st' isn't known

这样的错误。看来编译器不能准确识别st这个变量，我们来看看st是如何定义的。

struct _stat64i32 st;

这四处的定义都一样。struct好理解，那\_stat64i32是啥？经过查找，\_stat64i32的定义在C:\\MinGW\\include\\sys\\stat.h中

也就是说，struct \_stat64i32 \_\_struct\_stat\_defined( \_\_off32\_t, \_\_time64\_t );被声明的条件必须是\_\_MSVCRT\_VERSION\_\_ >= \_\_MSVCR80\_DLL，那么\_\_MSVCRT\_VERSION\_\_ 是多少呢？

查看C:\\MinGW\\include\\msvcrtver.h

     */
    # define __MSVCRT_VERSION__  __MSVCR60_DLL
    #endif

可知\_\_MSVCRT\_VERSION\_\_ 的默认值是\_\_MSVCR60\_DLL，说明MinGW 默认链接的是 msvcrt.dll，显然不满足\_\_MSVCRT\_VERSION\_\_ >= \_\_MSVCR80\_DLL的要求。那么，我的windows系统里到底有哪些版本的MSVCRxx.DLL呢？

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3JlbnBlbmcwMDk2NzI_size_16_color_FFFFFF_t_70 8][]

由此可见，我的C:\\Windows\\System32下只有MSVCR100.DLL、MSVCR110.DLL、MSVCR120.DLL这三个。当然，msvcrt.dll是肯定有的。

解决这个问题有两个思路，一是自行定义\_\_MSVCRT\_VERSION\_\_的值，让它大于等于 \_\_MSVCR80\_DLL，比如我这里可以令\_\_MSVCRT\_VERSION\_\_=\_\_MSVCR100\_DLL，用记事本打开C:\\AWTK\\SDK\\awtk\\awtk\_config.py，找到

elif TOOLS_NAME == 'mingw' :
        OS_LIBS=['kernel32', 'gdi32', 'user32', 'winmm','imm32','version','shell32','ole32','Oleaut32','Advapi32','oleaut32','uuid','stdc++']
        OS_FLAGS='-DWINDOWS -D_CONSOLE -g -Wall'
        COMMON_CFLAGS=COMMON_CFLAGS+' -std=gnu99 '
        COMMON_CCFLAGS=COMMON_CCFLAGS+' -DWITH_DOUBLE_FLOAT -DUNICODE '

修改为

但是这个思路有个弊端，那就是要求系统必须有指定版本的MSVCRxx.DLL，编译出来的程序可能无法顺利在其他电脑上运行，要不就是程序所在的目录必须附带指定版本的MSVCRxx.DLL。

第二个思路还是利用msvcrt.dll，这个动态库windows系统都有，而且MinGW默认也是链接它。打开C:\\AWTK\\SDK\\awtk\\src\\platforms\\pc\\fs\_os.c，搜索\_stat64i32并替换为\_stati64，保存。

顺利解决掉一个问题了，继续编译。还是scons

    #include "common/main.inc"

有个wmain函数，但这不是标准的入口函数。源码最后一行写着\#include "common/main.inc"，我们来看看C:\\AWTK\\SDK\\awtk\\tools\\common\\main.inc的源码

#include "common/utils.h"
    
    #ifndef WIN32
    int main(int argc, char* argv[]) {
      int ret = 0;
      wchar_t** argvw = argvw_create(argc, argv);
    
      ret = wmain(argc, argvw);
      argvw_destroy(argvw);
    
      return ret;
    }
    #endif /*WIN32*/

咦，这里有main函数呀，在main函数内部调用了wmain函数。难道是\#ifndef WIN32造成的？从上文fs\_os.c的报错来看，WIN32应该是定义过了，不然也不会报错

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3JlbnBlbmcwMDk2NzI_size_16_color_FFFFFF_t_70 11][]

既然WIN32被定义过，那么\#ifndef WIN32便不成立，main函数也不会被编译。看到这里，大体上可以猜测作者的意图是只有编译控制台程序时才编译main函数，但是你好歹给个WinMain函数呀。返回头来，咱们再看看bsvg\_gen.cc是要实现什么功能的

> \#\#\#\# 1.BSVG 生成工具。
>

>

> \* bsvg\\\_filename bsvg文件名。  
> \* bin 是否生成二进制格式(目标平台有文件系统时使用)，缺省生成C语言常量数组。

可见，这应该就是标准的控制台程序，我们尝试把\#ifndef WIN32和\#endif注释掉，再次编译看看。OK，顺利生成了bsvggen.exe。不过，又出现了新问题。

    #endif /*WITH_SOCKET*/

还是从报错情况来分析，\#ifdef WITH\_SOCKET和\#ifdef WIN32应该都是成立的（在awtk\_config.py中有WITH\_SOCKET的定义），那么必定有

#include "windows.h"
    #include <winsock2.h>
    #include <ws2tcpip.h>

然而在MinGW中，要想使用winsock2，应该在链接时添加参数-lws2\_32来链接到ws2\_32.dll，所以解决这里的问题也有两个思路，要么添加链接参数-lws2\_32，要么在awtk\_config.py去掉WITH\_SOCKET的定义。我们这里采用前者，用记事本打开C:\\AWTK\\SDK\\awtk\\awtk\_config.py，找到

elif TOOLS_NAME == 'mingw' :
        OS_LIBS=['kernel32', 'gdi32', 'user32', 'winmm','imm32','version','shell32','ole32','Oleaut32','Advapi32','oleaut32','uuid','stdc++']

修改为

elif TOOLS_NAME == 'mingw' :
        OS_LIBS=['kernel32', 'gdi32', 'user32', 'winmm','imm32','version','shell32','ole32','Oleaut32','Advapi32','oleaut32','uuid','stdc++','ws2_32']

再编译一下试试

嗯。。。错误似曾相识（上文）。还是从源码入手，先看C:\\AWTK\\SDK\\awtk\\demos\\demo1\_app.c，最关键的还是这一句

#include "awtk_main.inc"

我们把代码整理一下，单独看入口函数

#ifdef USE_GUI_MAIN
    int gui_app_start(int lcd_w, int lcd_h) {
    
    #elif defined(MOBILE_APP) && defined(WITH_SDL)
    int SDL_main(int argc, char* argv[]) {

    int WINAPI wWinMain(HINSTANCE hinstance, HINSTANCE hprevinstance, LPWSTR lpcmdline, int ncmdshow) {
    
    #else
    int main(int argc, char* argv[]) {

这下看的就比较明晰了，gui\_app\_start()是用于无操作系统的裸机程序，SDL\_main()用于手机APP，wWinMain()用于win32程序，main()用于控制台程序。在这些条件编译里面，成立的显然是\#elif defined(WIN32)，但为何提示找不到入口函数呢？难道是编译器不认识wWinMain()函数？嗯。。。还真的是，wWinMain()函数是WinMain()宽字符版，下面引用[https://www.cnblogs.com/Dageking/archive/2014/01/15/3520406.html][https_www.cnblogs.com_Dageking_archive_2014_01_15_3520406.html]的一段描述

> 在Windows环境中，编译器的翻译策略是GB2312到UCS-2BE；Linux环境中的策略是UTF-8到UTF-32BE。  
> 这时候就要求源文件的编码与编译器的本地化策略集中代码翻译的策略一致，例如VC只能读取GB2312的源代码（这里还是例外，VC太自作聪明了 ，会将很多其他代码在编译时自动转换成GB2312），而gcc只能读取UTF-8的源代码（这里就有个尴尬，MinGW运行win32下，所以只有 GB2312系统才认；而MinGW却用gcc编写，所以自己只认UTF-8，所以结果就是，MinGW的宽字符被废掉了）。

看来是MinGW在windows下不支持宽字符，那我们还是用WinMain()好了。打开C:\\AWTK\\SDK\\awtk\\src\\awtk\_main.inc，将wWinMain()函数修改为

int WINAPI WinMain(HINSTANCE hinstance, HINSTANCE hprevinstance, LPSTR lpcmdline, int ncmdshow) {

问题顺利解决，再次编译，生成了一堆demo程序，运行一个看看

不过，还是有新问题

说是新问题，其实老问题，哈哈。修改原理同上。

5、直到看到这一句

才真正表明编译完全通过。

让人感到不解的是，有两个编译出来的程序竟然被卡巴斯基杀掉了，晕。。。

6、后记

为了加快编译速度，可以使用多线程编译，在scons后加参数-jx，x代表线程数，在使用多线程编译前需要安装pywin32。

pip install pywin32

7、后记的后记

这篇文章还没写完，ZLG官方已修复上述问题（我反馈的），但是必须到github更新最新源码，AWTK-Designer-x64-0.1.3-Preview-Setup安装包自带的SDK（1.3版）还是存在以上问题。
