qt-- 学习笔记11（生成执行文件exe，报错)

总结：编译器版本和windeployqt版本不匹配导致的生成的exe文件运行不了。

问题描述：

ChartZoomMove.exe-系统错误，由于找不到 libgcc s dw2-1.d，无法继续执行代码。重新安装程序可能会解决此问题。

打包命令如下：

C:\Users\1\Desktop\release>"D:\Qt\Qt5.15.2\5.15.2\mingw81_32\bin\windeployqt.exe" ChartZoomMove.exe

打包过程：
C:\Users\1\Desktop\release>"D:\Qt\Qt5.15.2\5.15.2\mingw81_32\bin\windeployqt.exe" ChartZoomMove.exe
C:\Users\1\Desktop\release\ChartZoomMove.exe 32 bit, release executable

从打包过程和报错信息找到原因：

你的实际 ChartZoomMove.exe 是用 dw2 异常模型的 MinGW 编译的，但你用来部署的 windeployqt 所在目录对应的 MinGW 使用的是 seh 异常模型。

这两者不兼容，导致：

 程序运行时需要 libgcc_s_dw2-1.dll，
 但 windeployqt 带的是 libgcc_s_seh-1.dll，
因此系统报缺少 libgcc_s_dw2-1.dll。

这是Qt_5_15_2_MinGW_32_bit编译器编译时候实际使用的编译器路径D:\Qt\Qt5.15.2\Tools\mingw810_32\bin\gcc.exe，可能是安装或者什么原因默认的这个路径，前面打包的路径是D:\Qt\Qt5.15.2\5.15.2\mingw81_32\bin\windeployqt.exe，所以windeployqt.exe和编译器路径版本不匹配导致动态出现问题。

在该编译器路径下面没有对应的windeployqt.exe文件，因此使用D:\Qt\Qt5.15.2\Tools\mingw810_32\bin\gcc.exe编译完成就会打包不了，暂时打包问题解决不了。

复制libgcc_s_dw2-1.dll到文件夹下，不提示缺少动态库，但是仍然运行不了报错0x0000007b，

还是需要编译器和windeployqt版本匹配，不然运行不了。
