After building, install the shared library libdamlev.so to the plugins directory of your MySQL installation.

Does the file libdamlev.dll exist in your plugin directory?

[sahannn]

Yes there is in the plugin directory I tried the release Version 1.0 Beta download. I'm trying for windows.

I created and tried the new version. It didn't work either.

Same problem here, on two different Windows (7 & 10) machines.

• Drop libdamlev.dll into C:\Program Files\MySQL\MySQL Server 8.0\lib\plugin
• Issue any of the CREATE FUNCTION damlev... commands
• Get ERROR 1127 (HY000): Can't find symbol 'damlev...' in library

do you know what is the solution?

Sorry, no. Will try to take a look at the code and compile it, but probably won`t have the time to do so this week...

If you find a solution, please let me know

Hi Sahann,

Well, I got it working! The function names weren't being exported, so I had to add __declspec(dllexport) and __cdecl to each function declaration in the extern "C" {} groups, in each class. Then I compiled under Visual Studio, and everything worked.

Here's a copy of the dll file I'm using, Works great under MySQL 8.0! https://tinyurl.com/bepjkk6h

Thank you, can you share the revised source code as well virtual studio

The link does not work anymore. Maybe you can submit the file to the project so they replace the one in the Releases section

Hi. I fixed the link (https://tinyurl.com/bepjkk6h). It doesn't work (for me) if you click on it inside Github, but if you copy the link to the address line, it will download the file. I can't guarantee how long the file will be available, although it should be at least a few months. And I'm sorry, I no longer have the source code. I ended up not using this library for my application, and the source code eventually got lost. Also, here's the file, attached to this comment: libdamlev.zip .

It'd be awesome if you could make a pull request with your fix. Unfortunately I do not have access to that platform to do it myself.
