FOSS gamedev and creative worlds

Hi, how can I find out if the LuaJIT is working? I compiled the code by myself and enabled the LuaJIT, but I want to make shure that he is really working

Use `cmake -LH | grep USE_LUAJIT` (or `cmake-gui` if you have it). It should be set to 1 or something else recognizable as "enabled".

From Lua, try if `require "jit"` succeeds.

Thx, with your hint I found this code



Returns LuaJIT 2.0.2 so I think the Jit is availible. But can I benchmark this? Or do I have to compile minetest without without JIT and compare the performance?

Pause menu. Check for "USE_LUAJIT=1".

You need to do exactly that.

If the piece of code you want to benchmark does not depend on Minetest features, it's better to install stock Lua and LuaJIT as command-line tools and benchmark using them.
