Make for iOS platform no longer working. Giving arch error as armv7 and armv7s removed from > iOS 11.0

I was trying to build the cpprestsdk for iOS platform. But getting below error

clang: error: invalid iOS deployment version '-mios-simulator-version-min=11.2', iOS 10 is the maximum deployment target for 32-bit targets [-Winvalid-ios-deployment-target]

cmake.toolchain file needs to be updated for latest changes in iOS 11.0 . As I am very new to CMake and C++, not sure where and what changes to do.

Any help would be really helpful. Thanks.

@aksswami I created a PR that should help you past this.

#776

Thanks @mobileben.

I was able to build this using some other toolchain for ios cmake and editing cmake file for iOS. But as I am new to CMake not very sure if the changes were correct. This will really help as build process and other parts are out of date on this.

Thanks again!

@aksswami most toolchains for iOS are about the same. Although I don't believe they all work correctly since toolchains cannot access variables set outside of the tool chain (for the most part).

This was why I bridged over the deployment version through an environment variable. Not my first choice, but I could not get global properties to work right.

I am by no means a cmake pro ... rather I can do the basics. So it could also be it I was using the tooling incorrectly.

Much of the iOS stuff is out of date or partially described.

It is best to build boost from here

https://github.com/faithfracture/Apple-Boost-BuildScript

If you want static libs (which is what I use), I have a PR there to build a universal fat binary (or you can go to my fork).

I have a hacky script to build openssl here. It really isn't meant to be iron clad. It does what I need it to do so I haven't refined it to be more forgiving.

once those pieces are in place, then it's very buildable (using my PR).

Thanks for the info. I am using this https://github.com/krzyzanowskim/OpenSSL for OpenSSL on both OSX and iOS and things are working fine, as I just tested your PR.

My script also builds MacOS (or rather should). Definitely use what works best for your situation.
