MacOS libcvextern.dylib from v4.5.1 works under M1 Roseta, but v4.5.2 don't/crash app #542

Recently i upgrade from v4.5.1 to v4.5.2.
I compiled the cvextern to some OSes to bundle with the app.
Mac start to give problems if compiled with BigSur but i manage to get it to work if i use Catalina or Monjave to compile the libcvextern and then it will work on Big Sur without problem.

But the real problem comes on M1 users using the app in Rosetta 2 Emulation Mode, before with v4.5.1 it works just fine on that , but now with new v4.5.2 it never works, crashing the app on start.

I made a diff with otool, but is hard to know what is missing: https://www.diffchecker.com/aXry9pU7
Maybe libtesseract.4.dylib and liblept.5.dylib? They are not generated on build.

Our official commercial release v4.5.2 for macos binary do not have this issue:

It has dependency to libusb, which is also included in the release package & nuget packages. It doesn't contains reference to libtesseract or liblept.

(base) % file libcvextern.dylib 
libcvextern.dylib: Mach-O universal binary with 2 architectures: [x86_64:Mach-O 64-bit dynamically linked shared library x86_64] [arm64]

libusb-1.0.0.dylib (for architecture arm64):	Mach-O 64-bit dynamically linked shared library arm64

They are build on MacOS BigSur, of which the ARM64 components are built on Apple M1 and the x86_64 components are built on Intel CPU, then merged into a FAT binary. You can use the official 4.5.2 commercial release with dotnet 6 preview running natively on Apple M1. We tried and it works quite well. However we will not be officially supporting it until Microsoft official make a dotnet 6 stable release.

If you are building from source code, and if you have installed libtesseract using homebrew, opencv will pick up tesseract from your system. You should remove libtesseract and liblept from your build system. If you want to keep libtesseract on your system, you should set the CMake flag -DWITH_TESSERACT:BOOL=OFF to remove dependency on libtesseract and liblept. You should also set the CMake flag -DEMGU_CV_WITH_DEPTHAI:BOOL=OFF to remove the dependency on libusb. FYI, we have not tested this combination so we will not be able to provide further instructions if you run into any issues.

Hope that helps.

If it make life easier, I can sent you a copy of the libcvextern.dylib from our official mac os release.

Please send me an email canming@emgu.com

I can reply with a copy of the Mac OS binary for 4.5.2 release for you to use under GPL v3.

Your libcvextern.dylib has not changed the load path

Yes, that's the latest official release with libtesseract on it, but after unpacking that release you need to replace the libs by these ones: https://we.tl/t-mzXJcpCAKq which i'm currently testing but without success. That libcvextern have the libusb on rpath but still don't work. If you try to copy them both (libcvextern and libusb-1.0.0) and replace at UVtools contents root, it will not run without libusb installed.

If it make life easier, I can sent you a copy of the libcvextern.dylib from our official mac os release.

Ok that will be good, i will email you, but i also would like to know what i'm doing wrong.

Here my steps, after fresh install Monjave, catalina or bigsur:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
brew analytics off
brew install git cmake mono libusb
git clone https://github.com/emgucv/emgucv emgucv 
cd emgucv
git submodule update --init --recursive
cd platforms/macos
sudo ./configure

What i'm doing wrong here?

PS: UVtools is under AGPL v3, does it comply with GPL v3?

Looks like you are using the development code, I would suggest using a Tagged stable release, e.g. 4.5.2.

If you check out the tagged 4.5.2 release, it will produce

libcvextern.dylib:
	@rpath/libcvextern.dylib (compatibility version 0.0.0, current version 0.0.0)
	@rpath/libusb-1.0.0.dylib (compatibility version 4.0.0, current version 4.0.0)

instead of

libcvextern.dylib:
	@rpath/libcvextern.dylib (compatibility version 0.0.0, current version 0.0.0)
	/usr/local/opt/libusb/lib/libusb-1.0.0.dylib (compatibility version 4.0.0, current version 4.0.0)

at least that is what is produced on our mac CI build server (Intel Mac, BigSur).
You can also manually change the load path depends on your requirement using this command:
install_name_tool -change /usr/local/opt/libusb/lib/libusb-1.0.0.dylib @rpath/libusb-1.0.0.dylib libcvextern.dylib

I think AGPL v3 is compatible with GPL v3 but I am not 100% sure. You may want to check with someone that is specialized with the license law.

Ok i tested again with new compilation and make sure everything is rpath. Still fails. Installing libusb with brew solve the situation.
Here the video to prove i'm not crazy: https://youtu.be/_bVdVxC_tHY
