CMake錯誤-使用柯南

Question

我只是想不出為什么我會收到此錯誤，有人願意給我一些幫助嗎？

我已經將Cmake添加到環境變量中，但是仍然出現錯誤。 我目前是一名試圖讓SDL正常工作的大學生。

我的機器是x64，我安裝了Visual Studio 2017，其中安裝了所有C ++元素。

這是CMD錯誤： CMD錯誤

這是GUI錯誤： GUI錯誤

復制-粘貼CMD版本：

（我也嘗試過手動構建（缺少柯南安裝--build））

“我的機器是x64，我安裝了Visual Studio 2017，其中安裝了所有C ++元素。”

您正在為錯誤版本的Visual Studio生成解決方案。

cmake .. -G "Visual Studio 14 2015 Win64"

將批處理腳本中的該行更改為：

cmake .. -G "Visual Studio 15 2017 Win64"

然后，您必須刪除所有生成的文件（ CMakeCache.txt', 'CMakeFiles dir等），然后重試。 還請仔細檢查您的柯南配置文件設置是否與您使用的編譯器匹配。
