Cross compile from x86_64-unknown-linux-gnu to aarch64-apple-darwin fails #679
Description
I came across this error and wanted to document it here in case it's of help. I was compiling bdk which also compiles secp256k1-sys and when trying to cross-compile to aarch64-apple-darwin from x86_64-unknown-linxu-gnu, compilation fails with gcc: error: unrecognized command-line option ‘-arch’.
This stackoverflow answer suggests that -arch is only for gcc with xcode, which means I wouldn't be able to cross-compile.
Below is the full error log I got:
[I] calvin@bitcoin ~/b/r/r/utreexod (main)> cargo build --release --target=aarch64-apple-darwin
Compiling secp256k1-sys v0.8.1
Compiling bip39 v2.0.0
Compiling weedle2 v4.0.0
Compiling uniffi v0.25.0
The following warnings were emitted during compilation:
warning: gcc: error: unrecognized command-line option ‘-arch’
warning: gcc: error: unrecognized command-line option ‘-arch’
error: failed to run custom build command for `secp256k1-sys v0.8.1`
