Failed to build x86_64-apple-darwin binary on ARM silicon

[jiabochao]

hi, when I compile the rust-ffmpeg x86 program on Apple M2 Pro macOS 15.1, I get an error

Cargo.toml

ffmpeg-next = {git = "https://github.com/zmwangx/rust-ffmpeg.git", branch = "master"}

error message:

error: failed to run custom build command for `ffmpeg-sys-next v7.1.0`

Caused by:

Did you solve it?

Did you solve it?

@caobug Try this

1. Install Rosetta2 via terminal using:

/usr/sbin/softwareupdate --install-rosetta --agree-to-license

2. Once Rosetta 2 is installed, install Homebrew for the x86_64 chip.

arch -x86_64 /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

3. Then install the x86_64 version of the ffmpeg libraries.

arch -x86_64 /usr/local/bin/brew install ffmpeg

arch -x86_64 /usr/local/bin/brew install pkg-config

4. Set PKG_CONFIG env （pkg-config bin path）

# use your own pkg-config path
export PKG_CONFIG=/usr/local/Cellar/pkg-config/0.29.2_3/bin/pkg-config

5. build rust-ffmpeg again
