macOS上执行configure时，报错：
running CONFIG_SHELL=/bin/sh /bin/sh ./configure --host aarch64-linux-android host_alias=aarch64-linux-android CC=/Users/XXX/Library/Android/sdk/ndk/25.2.9519653/toolchains/llvm/prebuilt/darwin-x86_64/bin/aarch64-linux-android21-clang --no-create --no-recursion configure: error: cannot find required auxiliary files: config.guess config.sub make: *** [config.status] Error 1
原因是使用了2.71版本的autoconf，需要回退到2.69版本。
如果是使用brew安装的autoconf，需要先指定安装2.69版本，再强制link：
brew install [email protected] brew link --overwrite [email protected] autoconf -V
autoconf (GNU Autoconf) 2.69
或者先unlink再link：
brew install [email protected] brew unlink autoconf brew link [email protected] autoconf -V
autoconf (GNU Autoconf) 2.69
如果直接link会报错：
Linking /usr/local/Cellar/[email protected]/2.69... Error: Could not symlink bin/autoconf Target /usr/local/bin/autoconf is a symlink belonging to autoconf. You can unlink it: brew unlink autoconf To force the link and overwrite all conflicting files: brew link --overwrite [email protected] To list all files that would be deleted: brew link --overwrite --dry-run [email protected]
其实以前直接用brew switch [email protected]就行了，但是后来brew移除了brew switch命令：https://github.com/orgs/Homebrew/discussions/339
