Hello Adolf,

Could you tell us my about why this is necessary?

The library should have a stable ABI so whenever they are being compiled independently from each other, they should still work.

Best,
-Michael

Hi Michael,

Earlier this year someone had a problem where nut wouldn't work because it was not linked to the correct libusb library and libusb had been updated in 2024. I thought that this had been a problem of a failure in a library link after an update because nut had not been shipped.

Withy you asking the question I went back and looked at the failures that had been reported and recognised a problem I had seen before with nut.

The problem, the user had was not due to a incorrectly linked library but due to a regression in nut where they ended up making the library requirement to libusb-1.0.so and not to libusb-1.0.so.0 or libusb-1.0.so.0.4.0

This issue of linking to libusb-1.0.so had been fixed in nut-2.7.4 but somewhere between there and nut-2.8.2 it came back. They have now fixed this again in the latest version which is in CU196 (nut-2.8.3)

So the message is not required in the lfs file and my patch can be rejected.

I obviously didn't read the details of the issue reported in the forum closely enough and missed that it was the direct .so file being required.

Regards,

Adolf.
