Hi all, I’m getting a similar error to Java SWT app doesn't work. Missing library, but the methods mentioned there don’t appear to be fixing the problem.
I’m trying to package some proprietary stm32 IDE for nixos, but I’m running into this error:

(this is my first time packaging something for Nix, so am new to this).
I tried to apply the methods mentioned above, but when I put the -cp in the ini file, it completely fails to start (as opposed to previously generating the error message above).
