Question

在基于Qt 5.11.2（MSVC 2015，32位）的QtCreator 4.7.2中生成发行文件夹时，我有些麻烦。我的程序在调试版本中运行得很好，但是当我将构建版本更改为发行版本时，会出现编译器错误。

我在应用程序内使用QCustomPlot库，并且在发行版中以某种方式不喜欢

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

这使我得到一个 C2446：'：'：没有从'QLatin1String'到'QStringBuilder'的转换

所以我将测试行替换为

integerPart > 0 ? "" : ""

，因此编译器不再抛出任何错误，但是现在我得到一个 LNK1158：无法运行'rc.exe'

我尝试清理构建并运行qmake，但链接器错误并未消失。任何想法可能导致此问题？我只是从调试切换到发布。

转到此文件夹

C：\ Program Files（x86）\ Windows Kits \ 10 \ bin \ 10.0.17763.0 \ x86

并将 rc.exe 和 rcdll.dll 复制到以下文件夹

X64

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

Qt Creator调试有效，但无法编译发行版
