Qt Creator Debug 有效但无法编译 release

Question

我在基于 Qt 5.11.2（MSVC 2015，32 位）的 QtCreator 4.7.2 中生成发布文件夹时遇到了一些问题。我的程序运行在调试版本中运行良好，但是当我将构建更改为发布版本时，出现编译器错误。

我在我的应用程序中使用了 QCustomPlot 库，但不知何故在发布版本中它不喜欢

integerPart > 0 ? QString::number(integerPart)+QLatin1String(" ") : QLatin1String("")

这给我一个 C2446: ':': 没有从 'QLatin1String' 到 'QStringBuilder'

的转换

所以我用

替换了测试行

integerPart > 0 ? "" : ""

所以编译器不再抛出错误，但现在我得到一个 LNK1158: cannot 运行 'rc.exe'

我尝试清理构建和运行 qmake，但链接器错误并没有消失。有什么想法会导致这个问题吗？我只是从调试切换到发布。

转到此文件夹

C:\Program Files (x86)\Windows Kits\bin.0.17763.0\x86

并复制rc.exe和rcdll.dll到以下文件夹

X64

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\x86_amd64
