我正在尝试在 ubuntu 16.04 上安装 cryengine 5。我正在使用他们提供的源代码和 sdkgithub 仓库。这是我使用的编译命令：
./cry_waf.sh build_linux_x64_gcc_profile --project-spec=gamesdk
在此之前我所做的就是将 GameSDK 内容复制到 CryEngine 的root/Code/SDKs文件夹中。
这是我收到的错误：

此外，我收到以下警告和错误：
[WARNING] No default compiler found, enabling compiler auto-detection
[WAF] Executing 'build_linux_x64_gcc_profile' in '/home/cortana/Desktop/CRYENGINE-5.1.1/BinTemp/linux_x64_gcc_profile/_shared'

[ERROR] Attempting to build CryAudioImplWwise, but could not find the Wwise SDK at Code/SDKs/Audio/AK, skipping.
我不明白为什么会出现这些错误以及如何删除它们。我已经安装了 g++，所以不应该出现第一个警告。对于sdl_mixer，我安装了libsdl2-dev和libsdl2-mixer-dev，它仍然说缺少二进制文件。我已经从存储库下载了整个 GameSDK，但它仍然说缺少某些内容。我该如何解决这些错误并编译和运行 Cryengine？
答案1
很简单！在互联网上搜索了很多次后，我什么也没找到，但答案是在 cryengine 网站上，但他们使用（可选）。只需打开终端并输入
sudo apt-get 安装 clang
然后放
./cry_waf.sh build_linux_x64_clang_profile --project-spec=gamesdk
并不是
./cry_waf.sh build_linux_x64_gcc_profile --project-spec=gamesdk
