I'm new to this, so i'm gonna need some help. I built LZDoom for Linux (I cloned the g3.3mgw branch, that's the 3.87 dev), but i can't get a mod to run (in this case Hideous Destructor). Everytime i try to run it , i get this error:
lzdoom: /home/vlada/lzdoom/src/scripting/backend/codegen.cpp:1921: virtual ExpEmit FxMinusSign::Emit(VMFunctionBuilder*): Assertion `ValueType == Operand->ValueType' failed.
Aborted (core dumped)
I had a friend of mine check, LZDoom dev does support the latest dev version of the mod, and i also checked if i did something wrong, so i tried another mod and it works. I asked HD's dev and he has no clue why this happens.

That's a debug assert - that means you built a debug build, not a release one. I don't know on Linux, but on Windows, it'd give you a popup that lets you choose whether to abort, continue, or load a debugger.
You have to recompile LZDoom as a release build. Debug builds are compiled with debug code on and no optimizations, so they're way slower.

It would be helpful to find out what code causes the assert.

Minimal sample would be something like this
class MinusMemberCast : Actor

Not that again. Emit normally has no use for types, it should check registers instead, if possible.

So how so i compile a release build? Do i just run cmake like this
Or is there something else to it?

Yep, that works. Thanks for the help
