Build for ios

[AJenbo]

For testing using the simulator:

cmake -S. -Bbuild -G Xcode -DCMAKE_TOOLCHAIN_FILE=../CMake/ios.toolchain.cmake -DPLATFORM=SIMULATOR64

For running on a real device:

cmake -S. -Bbuild -DCMAKE_TOOLCHAIN_FILE=../CMake/ios.toolchain.cmake  -DENABLE_BITCODE=0 -DPLATFORM=OS64
cmake --build build -j $(sysctl -n hw.physicalcpu) --config Release
cd build
mkdir Payload
mv devilutionx.app Payload
zip -r devilutionx.ipa Payload

Open the generated Xcode project.

Add the MPQ files

• Add CI build

[JoBergeron]

To distribute the iOS version, you could package a .IPA and hand that out. After people install it using something like AltServer, you could simply have the user copy the .MPQ to a folder on their phone.

[AJenbo]

@JoBergeron do you know how the app would then locate or gain access to the mpq file?

[JoBergeron]

Launching the app could create a local folder where it would look for the file. You could inform the user to simply copy the file there. iOS apps can create a local folder on the user's device.

That sounds perfect. Do you have any references for that?

I know RetroArch does stuff like that. https://github.com/libretro/RetroArch

I found this code from an example somewhere that could help as well

do
{
// Find Application Support directory
let fileManager = FileManager.default
let appSupportURL = fileManager.urls(for: .applicationSupportDirectory, in: .userDomainMask).first!
// Create subdirectory
let directoryURL = appSupportURL.appendingPathComponent("com.myCompany.myApp")
try fileManager.createDirectory (at: directoryURL, withIntermediateDirectories: true, attributes: nil)
// Create document
let documentURL = directoryURL.appendingPathComponent ("MyFile.test")
try document.write (to: documentURL, ofType: "com.myCompany.test")
}
catch
{
print("An error occured")
}

In my previous local builds I just embedded .mpq into the Xcode project, as a resource file. This made it much easier to run things, without a need to point to these resources after launch. Should be possible with CMake too, but may not be practical for .ipa re-distribution.

[JoBergeron]

Distributing an .ipa file would also let people who don't have a Mac "sideload" the game. (Assuming they have a Windows PC)

I think you can use this to transfer mpq file.

That's one way to do it I guess. I simply put stuff on icloud or dropbox or even sometimes just on a network share.

[AJenbo]

That's another good method we should also support 👍

It would be more convenient to be able to read from cloud storage.

If you can use this, you can access iCloud.

You may need the T option to build with the new Xcode.

cmake .. -G Xcode -T buildsystem=1 -DCMAKE_TOOLCHAIN_FILE=../../ios-cmake/ios.toolchain.cmake -DPLATFORM=SIMULATOR64

https://cmake.org/cmake/help/latest/generator/Xcode.html#xcode-build-system-selection

[AJenbo]

Atm I only have Xcode 10.1 available to me :)

[bubio]

I tried it with Xcode 13, but if I didn't specify an old build system in the T option, the build failed.

Can you pick more than 1 file though? What if you want to load the hellfire mpq files as well?

Could you let me know what error you got, I have to patch 3 files in SDL because of my old Xcode.

[bubio]

I'm out now, so I'll check it when I get home.
Sorry.

Is it too late?
Errors are as follows.

I tried to build it in the following environment:
macOS: 12.0.1（21A559）
Xcode: Version 13.1 (13A1030d)

ld: building for iOS Simulator, but linking in dylib built for macOS, file '/usr/X11R6/lib/libpng.dylib' for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I do the following:
copy it from _deps/sdl2-build/Debug-iphonesimulator/ to Debug-iphonesimulator/
edit of line 33 in _deps/sdl2-src/src/stdlib/SDL_iconv.c: #if defined(HAVE_ICONV) && defined(HAVE_ICONV_H) -> #if 0

[glebm]

libpng stuff may be fixed by #3618

[AJenbo]

Note: Install instructions will be added along side #3612 as that will change the procedure.

@AJenbo
Cmake passed.
I got the following error in Xcode.
