Compilation on aarch64-apple-ios fails. #11

Open kmonkey opened 1 year ago

kmonkey commented 1 year ago

My project uses opus-rs v0.3.0 which references audiopus-sys v0.2.2. When I specified aarch64-apple-ios as the target to build for iOS, the following error was displayed.

(*'-') < cargo build --target aarch64-apple-ios --release                                                                                                                                                                                            [dev]

I don't know if it's the best way, but I was able to compile by setting some environment variables with reference to the link below. https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html#cross-compiling-for-ios-tvos-or-watchos

export CMAKE_OSX_ARCHITECTURES="arm64"                                                                                                                                                                                                                         
export CMAKE_XCODE_ATTRIBUTE_ONLY_ACTIVE_ARCH="NO"                                                                             
export CMAKE_IOS_INSTALL_COMBINED="YES"

The best way is to just pass the target to cargo and it will compile, any good ideas?

Thank you for the exports on iOS. Do you have an idea of what the env vars might be for android?

lgmarchi commented 8 months ago

I am having same problem yet, even after set CMAKE variables. @kmonkey Were you able to build for android as well?
