问题描述
有一个先前的问题不能升级到Mojave后，在Mac上编译C程序，其答案涵盖了出现问题的大多数变体.
There's a previous question Can't compile C program on a Mac after upgrade to Mojave, and the answers to that have covered most of the variations on what goes wrong.
现在-从2019年10月7日开始-您可以升级到macOS Catalina 10.15.同样，即使在升级(从Mojave 10.14.6)升级到Catalina之前安装了XCode 11.0，升级过程中/usr/include目录也被删除了.因此，编译器期望存在/usr/include目录，因此不再起作用.
Now — as of Monday 2019-10-07 — you can upgrade to macOS Catalina 10.15. Once again, during the upgrade, the /usr/include directory has been blown away by the update, even though XCode 11.0 was installed before upgrading (from Mojave 10.14.6) to Catalina. Consequently, compilers built to expect that there is a /usr/include directory do not work any longer.
针对Mojave问题的主要推荐步骤-使用命令:
The main recommended step for the Mojave issues — using the command:
open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg
不能正常工作，因为目录/Library/Developer/CommandLineTools/Packages/不存在(因此还没有要打开的.pkg文件).
does not work out of the gate because the directory /Library/Developer/CommandLineTools/Packages/ does not exist (so there's not yet a .pkg file to open).
是否有一种很好的(官方)方式来创建和填充目录/usr/include?
Is there a good (official) way to create and populate the directory /usr/include?
推荐答案
对我来说，向CPATH添加以下路径可以解决此问题:
For me adding the following path to CPATH solved the issue:
export CPATH=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/usr/include
