【问题描述】：
我编译了ffmpeg，编译器输出如下错误。
ld: warning: ignoring file libavdevice/libavdevice.a, building for macOS-arm64 but attempting to link with file built for macOS-arm64
ld: warning: ignoring file libavfilter/libavfilter.a, building for macOS-arm64 but attempting to link with file built for macOS-arm64

我不明白为什么macOS-arm64 不能链接到macOS-arm64。
arm64 目标文件不应该链接到 arm64 静态库吗？
我正在使用 M1 macbook，并使用以下命令配置 ffmpeg。
../configure --cc=/usr/bin/clang --prefix=/opt/ffmpeg --enable-avisynth --enable-fontconfig --enable-gpl --enable-libaom --enable-libass --enable-libbluray --enable-libdav1d --enable-libfreetype --enable-libgsm --enable-libmodplug --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenh264 --enable-libopenjpeg --enable-libopus --enable-librubberband --enable-libwebp --enable-libx264 --enable-libx265 --enable-libzimg --enable-libzmq --enable-version3 --pkg-config-flags=--static --disable-ffplay --extra-cflags="-I/opt/homebrew/include" --extra-cxxflags="-I/opt/homebrew/include" --extra-ldflags="-L/opt/homebrew/lib"

请不要在c题中标记c++

包含整个配置并将输出作为pastebin。

我尝试指定CC和LD的路径，根据回答，问题依然存在。也没有与该问题类似的预编译标头。
