We make sure the formulae work around such problems.īottom line: install both if you want to be able to use as many pre-built binary bottles as possible, and want to be able to build formulae that have a depends_on :xcode => :build. So outside of Homebrew you may have an easier time building software that doesn't know it can also find those headers in the Xcode SDK folder. Command Line Tools beta 5 for Xcode-11.0 Title: Command Line Tools beta 5 for Xcode, Version: 11. In this tutorial, you will install Command Line Tools as they are a more reasonable size. Clean macOS Catalina image doesnt contain Command Line Tools and homebrew installer tries to install it but fails: Command output. That said, there are files installed in, for example, /usr/include that you will only have if you've installed the CLT. In order to install Homebrew, you need to install either the Xcode Command Line Tools (about 100 MB) or the full Xcode package (about 10 GB).
Some users would prefer to use only the CLT because it's a much smaller download and takes less time to install and upgrade than Xcode. Most formulae can be built with just the CLT, and those that require the full Xcode.app have an explicit depends_on :xcode => :build. We ensure that all Homebrew formulae can be built with Xcode.app alone. So installing the CLT may help you avoid some lengthy source builds. They can still be built from source with Xcode only, but because the pre-built bottles are compiled in an environment that has both Xcode and the CLT installed, there are some cases where the bottles end up having a hard dependency on the CLT. In the script above I think that the command line tools are failing to install. However, there are formulae that will be forced to build from source if you do not have the CLT. Dont forget to install Xcode command line tools first. Is there a specific reason why brew requires the Command Line Tools package (in /Library/Developer/CommandLineTools/usr)
