macdeployqt again

[DuBu]

Hi all,

I'm trying to use macdeployqt on my Qt app (Qt 5.15.18), but it seems to have issues with transitive dependencies. It copies libraries into my bundle, but not libraries the library itself depends on. Is that a known issue?
For example It finds out libwebpmux.3.dylib is needed and copies it from /usr/local/lib/ into the bundle. (Surprisingly under Contents/Frameworks but anyway.)
Now, when I start my bundled app it crashes and in the Console app I see a crash log with the following lines:

Termination Reason:    Namespace DYLD, Code 1 Library missing
Library not loaded: @rpath/libsharpyuv.0.dylib
Referenced from: MyApp.app/Contents/Frameworks/libwebpmux.3.dylib
Reason: tried: 'MyApp.app/Contents/Frameworks/../lib/libsharpyuv.0.dylib' (no such file), 'MyApp.app/Contents/Frameworks/../lib/libsharpyuv.0.dylib' (no such file), 'MyApp.app/Contents/Frameworks/libsharpyuv.0.dylib' (no such file), 'MyApp.app/Contents/Frameworks/libsharpyuv.0.dylib' (no such file), '/usr/lib/libsharpyuv.0.dylib' (no such file, not in dyld cache)

When I execute otool -L MyApp.app/Contents/Frameworks/libwebpmux.3.dylib it says:

MyApp.app/Contents/Frameworks/libwebpmux.3.dylib:
	@executable_path/../Frameworks/libwebpmux.3.dylib (compatibility version 5.0.0, current version 5.0.0)
	@rpath/libwebp.7.dylib (compatibility version 9.0.0, current version 9.9.0)
	@rpath/libsharpyuv.0.dylib (compatibility version 2.0.0, current version 2.0.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1319.100.3)

So it seems libwebpmux.3.dylib depends on libsharpyuv.0.dylib. But that didn't find its way into the bundle. How can I fix this?

Hi,

The first thing you can do is try with a more recent version of macdeployqt from Qt 6 to check if it does things better.
Otherwise, use a bash script to copy and update the dependencies.

@SGaist Hi, I already did. But it doesn't work, it says:

dyld[50080]: Library not loaded: @rpath/QtCore.framework/Versions/A/QtCore
  Referenced from: <66AAD100-9E8A-35A8-B6DD-D1509FAEBAE6> ./macdeployqt
  Reason: tried: '../lib/QtCore.framework/Versions/A/QtCore' (no such file), '../lib/QtCore.framework/Versions/A/QtCore' (no such file)
[1]    50080 abort      ./macdeployqt

In Qt 6 the QtCore framework is in ../lib/QtCore.framework/Versions/A/, but unfortunately in Qt 5 its in ../lib/QtCore.framework/Versions/5/ or ../lib/QtCore.framework/Versions/Current/.

Worth a shot.

Did you run macdeployqt in verbose mode to check if there was any error message regarding the missing libraries ?

@SGaist Yes, it said libwebpmux depends on libsharpyuv but it didn't try to copy that one over. I found out libwebpmux is a dependency of a freerdp3 we use. So it seems macdeployqt either wasn't made for 3rd party libraries or it fails to handle them. It looks like I need to handle those dependencies by myself somehow.
