GetActivationModeA not found in LexActivator

General
#1

Platform: .NET 6.0
Environment: Docker (x86-64)
Container: Alpine Linux
NuGet: Cryptlex.LexActivator @ 3.19.1

We’re running a .NET 6.0 application published self-contained using linux-musl-x64 runtime, and catching an exception when calling GetActivationMode:

System.EntryPointNotFoundException: Unable to find an entry point named 'GetActivationModeA' in shared library 'LexActivator'.
   at Cryptlex.LexActivatorNative.GetActivationModeA
   at Cryptlex.LexActivator.GetActivationMode()

Same application works fine when running on Windows 10/11, we don’t currently run the application bare metal on any Linux platform other than in a container.

Is there a specific shared library version we should be using?

Dumping exports appears to confirm that entry point does not exist in the shared library in our distribution:

# apk add gcc
# nm -D libLexActivator.so

We did notice that the C# source does have a switch for non-Windows that dynamically links against GetActivationModeA instead of GetActivationMode. This seems to be a bug given that the distributed shared library for the linux-musl-x64 runtime doesn’t have any of those entry points.

Here is some more diagnostic information on the shared library that gets deployed along with our application:

Hi,

We have released a new version, please upgrade to the latest version for the fix.

#4

@adnan-kamili Unfortunately the latest version (3.19.4) does not resolve the issue. I have a minimal example that reproduces the behavior we are seeing (Alpine Linux / linux-musl-x64) but I cannot seem to upload on the forum. Is there a file transfer service you prefer or an e-mail address I can send the example to?

#5

Yes, an entrypoint was missing for this function. we have added the entry point. Please use 3.19.5. That should solve your problem.

#6

This specific issue has been resolved, and we will continue testing. Thank you for the prompt response and solution(s)!
