这亲爱的项目是 Linux 的一个开源 Darwin/OS X 模拟层。我用 git 下载了源代码并尝试用它构建，cmake但失败了。文档说我需要这些包：
clang 3.1+
GCC 4.6+ (yes, you still need GCC for header files)
libkqueue
libbsd
gnustep-base ("Foundation")
gnustep-gui ("Cocoa")
gnustep-corebase ("CoreFoundation")
libobjc2
libudev
openssl
libasound
libav
libgc
apt但我在软件中心找不到它们。还cmake显示了此结果：
No build type selected, default to Debug
This is a 64-bit build

我该如何构建 Darling 项目？
答案1
按照http://darling.dolezel.info/en/Build/Ubuntu
跳过 Multilib 部分。
我需要两个额外的包（手册中未提及）：
sudo apt-get install libltdl-dev libgl1-mesa-dev
答案2
你可以使用我的 PPA 安装 darling。别忘了添加 GNUstep PPA，它包含所需 GNUstep 库的多架构包，这样你就可以拥有 dyld32 和 dyld64。
