Bug 5031

Summary: Signing SDL2_image.framework is ambigious
Product: SDL_image Reporter: lennard.berger
Component: miscAssignee: Sam Lantinga <slouken>
Status: ASSIGNED --- QA Contact: Sam Lantinga <slouken>
Severity: major

Description lennard.berger 2020-03-15 10:23:53 UTC 
Dear SDL2 maintainers.
We are currently trying to embed SDL2_image into a consumer product using the SDL2_image.framework file on OSX.

With the introduction of the new signing policy we need to force sign framework files as well (SDL2, SDL2_mixer). With the other components this is not an issue.

When I try to do the following:

codesign -s "Developer ID Application: blab" --timestamp --options runtime --deep --strict -f SDL2_image.framework

Codesign responds with:

SDL2_image.framework: replacing existing signature
SDL2_image.framework: bundle format is ambiguous (could be app or framework)

I copied the executable binary distribution from the website. This works fine for SDL2.framework and SDL2_mixer.framework.

Looking at the contents of SDL2_image.framework/Resources/Info.plist indicates that the CFPBundleSupportedPlatforms key is set (which appeared to be a bug in earlier versions).

Any help on resolving the matter is greatly appreciated.
Comment 1 lennard.berger 2020-03-20 19:08:34 UTC 
I can verify that this is because the following Frameworks:

- FLAC.framework
- Opus.framework
- OpusFile.framework
- modplug.framework
- mpg123.framework

Do not have 

	<key>CFBundleSupportedPlatforms</key>
	<array>
		<string>MacOSX</string>
	</array>

set in the Info.plist files.
Adding these keys fixes the problem. How do you suggest we proceed? Should tickets at the upstream packages be created?

I'll take care of it for the next release, thanks!
