Fix building boost.locale for iOS and tvOS #64

Open kambala-decapitator opened 3 years ago

kambala-decapitator commented 3 years ago

I took the main idea from https://metashapes.com/blog/building-boost-locale-ios/

The build system causes the compiler statement to include “-arch arm” which will make the compiler try to build for armv4t which the iOS libraries do not support. I found no elegant way to solve this and had to edit the darwin.jam file and replace “-arch arm” with “-arch armv7” to get rid of it.

Also tried applying https://github.com/boostorg/build/pull/560, but it fixes only case when you build exclusively for arm64.

The idea to pass all flags to cxx and linker was taken from https://stackoverflow.com/questions/64553398/compile-boost-as-universal-library-intel-and-apple-silicon-architectures

Successfully tested using Xcode 11.7, 12.4 and 12.5.1 with the following command:

./boost.sh -tvos -ios --min-ios-version 10.0 --boost-libs 'locale' --boost-version 1.76.0 --no-framework

End of output:

P.S. I feel that utilizing <root> option might be the right way to go... (https://metashapes.com/blog/building-boost-locale-ios/ also uses it)
