Building iOS doesn't seem to work

[mobileben]

Okay this may be just plain old user error. I followed the steps, minus the building of boost and openssl, since I already have them pre-built (although boost is not a framework).

I am more or less doing these steps:

git clone https://github.com/cristeab/ios-cmake.git
pushd ios-cmake
git apply ../fix_ios_cmake_compiler.patch
popd
mkdir build.debug
pushd build.debug
cmake .. -DCMAKE_BUILD_TYPE=Debug
make
popd

Which was listed in the instructions. This generates errors.

Determining if the include file pthread.h exists failed with the following output:
Change Dir: /Users/me/Development/3rdParty/cpprestsdk/Build_iOS/build.debug/build.i386/CMakeFiles/CMakeTmp

Both the ios-cmake and the contents of this Build_iOS directory seem a bit old. Is this even buildable for iOS anymore? While probably ill-advised, I was using http_client, which is really what I want this lib for. Mainly because I have the server already using cpprestsdk and thought it would be more convenient if I could use the client too. Maybe though that is the wrong approach here.

So it looks like iOS.cmake needs another patch. It needs the following lines:

set(CMAKE_MACOSX_BUNDLE ON)
set(CMAKE_XCODE_ATTRIBUTE_CODE_SIGNING_REQUIRED OFF)

I got that from here.

BTW, is there any reason the approach of cloning iOS.cmake is being done? It just seems to add steps. Since there is no guarantee that iOS.cmake will be updated or even maintained in a way where it is compatible, it would sort of seem better to make an attribution to the source but have the version in use in Build_iOS. Cloning and patching just seems a bit off as an approach.

I'll try and do a build a bit later. In the meantime, it did finally run through cmake after the changes.

I'll update this once I do a complete build.

BTW for reference, I'm using cmake 3.8.0 and Xcode 8.3.2.

Okay, so this all seems to be running. I'm still integrating more of my client code into my game. But at least the initial calls I've been making work.

I've ended up forking ios-cmake: https://github.com/mobileben/ios-cmake

This one doesn't require a patch. And ideally I think we should streamline the build process for iOS by reducing the amount of steps needed to get someone going.

I also am not using the boost as a framework, but rather individual files. I made an update to cpp_find_boost.cmake to use either the framework or individual libraries. The libraries is easier right now because https://github.com/faithfracture/Apple-Boost-BuildScript really only builds the .a file. I'll be forking that and adding something to build the universal libraries.
