4 years ago Can you verify that all xcframework bundles are added to the linking flags (LDFLAGS) using -framework option.
In your case, some of those undefined symbols are defined in fontconfig but your linking command does not include -framework fontconfig.

4 years ago fontconfig.xcframework is correctly added to the list of libraries linked to the test-app binary :
There are so many frameworks, I can't really guarantee they are all linked using the -framework flag, but at least fontconfig is :

note the -framework fontconfig entry in the too long command above.

4 years ago Well, in your first post -framework fontconfig was not there. And Xcode does not truncate linking commands. I shared my opinion based on what I see in your logs. Most developers will make the same comment after seeing that message.
In your second post, -framework fontconfig is there but not all libraries are included in that linking command. And I'm pretty sure that you don't have undefined symbols errors for fontconfig in your second command.
Anyway, I don't have anything to add. I saw this error before and this is how I fixed it. If your logs are not complete, too long or it is difficult to for you to validate a few things then I don't have anything to add. Good luck finding the solution.

4 years ago Yes I have truncated the logs since they are pretty long. At least you pointed me to the beginning of the solution and i'm going to double check each library linking (checking for -framework
The build log still fails on fontconfig symbols though, despite the linking command correctly contains -framework fontconfig :
ld: warning: could not create compact unwind for _filter_frame: stack subq instruction is too different from dwarf stack size

Just in case. Do you know of any reason Xcode would not link with all the .xcframework I've added to the project for this target ?

4 years ago Solution was to ensure Xcode does recursive searching when searching for frameworks : (FRAMEWORK_SEARCH_PATHS build setting) :
If not recursive, probably because .xcframework directories are "deeper" than traditional .framework bundle and add another level of directories (per architecture), Xcode does not traverse directories and can't find the library/framework binaries, but only the top level .xcframework folders. I suggest you add that information to your documentation about importing frameworks (https://github.com/tanersener/mobile-ffmpeg/wiki/Importing-Frameworks) since Xcode does not set the searching of frameworks as recursive by default.
Thanks for having pointed me in the right direction.

Hi. Thanks for making a more comprehensible version of FFmpeg for iOS. I'm trying to make an iPad version, LGPL only that may run on a Mac too, using Apple Catalyst technology.
Description I'm trying to build the test-app (MobileFFmpegTest app as a Catalyst app)
Expected behavior Following the documentation about importing frameworks (https://github.com/tanersener/mobile-ffmpeg/wiki/Importing-Frameworks) but of course using xcframeworks instead of framework should make the test-app compilable. Or should it compile only if using the "full-gpl" prebuild frameworks ?
Current behavior Does not link :
