Warning: You are using macOS 14. We do not provide support for this pre-release version. It is expected behaviour that some formulae will fail to build in this pre-release version. It is expected behaviour that Homebrew will be buggy and slow. Do not create any issues about this on Homebrew's GitHub repositories. Do not create any issues even if you think this message is unrelated. Any opened issues will be immediately closed without response. Do not ask for help from Homebrew or its maintainers on social media. You may ask for help in Homebrew's discussions but are unlikely to receive a response. Try to figure out the problem yourself and submit a fix as a pull request. We will review it but may or may not accept it. ==> Fetching spidermonkey ==> Downloading https://archive.mozilla.org/pub/firefox/releases/91.13.0esr/source/firefox-91.13.0esr.source.tar.xz Already downloaded: /Users/brew/Library/Caches/Homebrew/downloads/68e47bea063615d286c43f7c1d09fe25f7bf708bb45cee4c7e93caf052f99ae6--firefox-91.13.0esr.source.tar.xz ==> Verifying checksum for '68e47bea063615d286c43f7c1d09fe25f7bf708bb45cee4c7e93caf052f99ae6--firefox-91.13.0esr.source.tar.xz' /usr/bin/env tar --extract --no-same-owner --file /Users/brew/Library/Caches/Homebrew/downloads/68e47bea063615d286c43f7c1d09fe25f7bf708bb45cee4c7e93caf052f99ae6--firefox-91.13.0esr.source.tar.xz --directory /private/tmp/d20230917-7029-16xp60o /usr/bin/env cp -pR /private/tmp/d20230917-7029-16xp60o/firefox-91.13.0/. /private/tmp/spidermonkey-20230917-7029-1hcjhy/firefox-91.13.0 /System/Library/Frameworks/Ruby.framework/Versions/2.6/usr/lib/ruby/2.6.0/fileutils.rb:128: warning: conflicting chdir during another chdir block ==> autoconf213 ==> ../configure --prefix=/usr/local/Cellar/spidermonkey/91.13.0_3 --enable-optimize --enable-readline --enable-release --enable-shared-js --disable-bootstrap --disable-jemalloc --with-intl-api --with-system-icu --with-system-nspr --with-system-zlib Creating Python 3 environment created virtual environment CPython3.9.18.final.0-64 in 1332ms creator CPython3Posix(dest=/private/tmp/spidermonkey-20230917-7029-1hcjhy/firefox-91.13.0/js/src/brew-build/_virtualenvs/common, clear=False, no_vcs_ignore=False, global=False) seeder FromAppData(download=False, pip=bundle, setuptools=bundle, wheel=bundle, via=copy, app_data_dir=/private/tmp/spidermonkey-20230917-7029-1hcjhy/firefox-91.13.0/.brew_home/Library/Application Support/virtualenv) added seed packages: pip==20.3.1, setuptools==51.0.0, wheel==0.36.1 activators BashActivator,CShellActivator,FishActivator,PowerShellActivator,PythonActivator,XonshActivator Re-executing in the virtualenv checking for vcs source checkout... no checking for a shell... /bin/sh checking for host system type... x86_64-apple-darwin23.0.0 checking for target system type... x86_64-apple-darwin23.0.0 checking whether cross compiling... no checking for Python 3... /private/tmp/spidermonkey-20230917-7029-1hcjhy/firefox-91.13.0/js/src/brew-build/_virtualenvs/common/bin/python (3.9.18) checking for wget... not found checking for ccache... not found checking for the target C compiler... /usr/local/Homebrew/Library/Homebrew/shims/mac/super/clang checking whether the target C compiler can be used... yes checking the target C compiler version... 10.0.0.or.more checking the target C compiler works... yes checking for the target C++ compiler... /usr/local/Homebrew/Library/Homebrew/shims/mac/super/clang++ checking whether the target C++ compiler can be used... yes checking the target C++ compiler version... 10.0.0.or.more checking the target C++ compiler works... yes checking for the host C compiler... /usr/local/Homebrew/Library/Homebrew/shims/mac/super/clang checking whether the host C compiler can be used... yes checking the host C compiler version... 10.0.0.or.more checking the host C compiler works... yes checking for the host C++ compiler... /usr/local/Homebrew/Library/Homebrew/shims/mac/super/clang++ checking whether the host C++ compiler can be used... yes checking the host C++ compiler versio
