error: Signing for "SDL2" requires a development team.

[matusfedorko]

Hi,

I am trying to build SDL 2 for iOS using cmake. First I cloned out the latest commit from the SDL2 branch and then I ran the following to configure build:

cmake -GXcode -S . -B ../sdl2_build/iOS -DCMAKE_SYSTEM_NAME=iOS -DCMAKE_OSX_SYSROOT=iphoneos -DCMAKE_OSX_ARCHITECTURES=arm64

And the following to build:

xcodebuild -project ../sdl2_build/iOS/SDL2.xcodeproj -target ALL_BUILD

Which produced the following output:

2023-09-05 21:24:24.558 xcodebuild[55313:5725471] DVTCoreDeviceEnabledState: DVTCoreDeviceEnabledState_Disabled set via user default (DVTEnableCoreDevice=disabled)
Command line invocation:
    /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -project ../sdl2_build/iOS/SDL2.xcodeproj -target ALL_BUILD

User defaults from command line:
    IDEPackageSupportUseBuiltinSCM = YES

What a I doing wrong ?

When I open the project in Xcode and build from Xcode, then the build succeeds. Why is it not working with xcodebuild ?

Does the problem also happen when you build with cmake --build ../sdl2_build/iOS?

This post suggests adding CODE_SIGNING_ALLOWED=NO to the build command.

Try configuring with -DCMAKE_XCODE_ATTRIBUTE_DEVELOPMENT_TEAM=matusfedorko. docs

[matusfedorko]

Thanks for your reply. Unfortunately cmake --build ../sdl2_build/iOS behaves the same, same error. Using CODE_SIGNING_ALLOWED=NO with xcodebuild worked. Although I still wonder why there is this difference between building through Xcode and building through xcodebuild ? Anyways I ended up with a different solution still, I only build static library. I don't need shared library and the error happens only when building SDL as a shared library.

Does the configuration type matter? Does it also happen with Debug (-DCMAKE_BUILD_TYPE=Debug)?

Have you tried configuring with -DCMAKE_XCODE_ATTRIBUTE_DEVELOPMENT_TEAM=matusfedork yet?

[matusfedorko]

Sorry for the slow reply. I tried -DCMAKE_BUILD_TYPE=Debug, but that makes no difference as it should. -GXCode is a multiconfig generator, so the it does not matter what is on the command line during configure step. Supplying development team still errored out, but with a different error this time :

error: No signing certificate "iOS Development" found: No "iOS Development" signing certificate matching team ID "matusfedorko" with a private key was found. (in target 'SDL2' from project 'SDL2')

I am sure I used a valid singing certificate and TeamID as I use it on other projects that compile successfully.

I guessed matusfedork for the development team name, perhaps another name fits better?

Does cmake --build ../sdl2_build/ios --config Release and cmake --build ../sdl2_build/ios --config Debug give the same result?

[matusfedorko]

Yes, I understood. Building both release/debug has the same outcome.
