Compilation and usage for LOVE2D

[GeTechG]

Can you please give instructions on how to compile for linux?

[sonoro1234]

From a sibling folder to the repo folder

cmake  -DCMAKE_BUILD_TYPE=RelWithDebInfo -DGLFW_PATH="Where to find GLFW package" -DIMPL_GLFW=yes -DIMPL_OPENGL2=yes -DIMPL_OPENGL3=yes -DIMPL_EXTRAS=yes -DLUAJIT_BIN="where LuaJIT is" ../luajit-imgui

make install

but if you use https://github.com/sonoro1234/anima it will build GLFW, SDL and LuaJIT-ImGui for you

[GeTechG]

Okay, honestly, I rarely collect anything because it's hard. What's an anima? I don't know what to do with it, so I need to clarify it for SDL2. If it's not difficult, how do you build it in more detail?

[sonoro1234]

https://github.com/sonoro1234/anima is my repo for working with opengl.
You should clone it.
From a sibling folder type
cmake -DLUAJIT_BIN="where you want to install everything" ../anima
make install

[GeTechG]

Okay, thanks, maybe I'll figure it out later, but I couldn't. Here's the conclusion. Maybe I should specify luajit in DLUAJIT_BIN, I did it in an empty folder.

cmake -DLUAJIT_BIN="./" ../anima

When you clone the repo you should do it recursively to also clone the git submodules.

For LUAJIT_BIN use ""/home/sergey/anima" for example

[GeTechG]

Okay, I did the first item, some files were not found there, but it went well. And "make install" at the end gave me errors.

[sonoro1234]

implot source was not up to date.
Now corrected.
do a new clone and try again please

[GeTechG]

Now it was 96% I decided to restart, but it didn't help.

Yes, it did help.
error is now saying that you need to install opengl developing files in your system.

google linux opengl

[GeTechG]

Ugh, it helped, the assembly was successful. I take it now everything has to be searched in the directory I indicated?

[sonoro1234]

I take it now everything has to be searched in the directory I indicated?

Yes

In the anima\examples\LuaJIT-ImGui\examples folder you will find the LuaJIT examples, you should run them from a terminal (or your prefered code editor) ./anima_launcher script_to_run_path

[GeTechG]

The thing is that I'm using the LOVE2D framework and I need to run it, I thought it would be at the end of the .so dynamic library and I could connect them.

[sonoro1234]

It is not a LOVE2D module but just a LuaJIT module. Someone has to port it to LOVE2D. Perhaps https://github.com/Jarodwr/love-imgui-wip but I have not tried it and it seems to need more work for linux building.

without using LuaJIT-imgui you have https://github.com/YoungNeer/lovely-imgui but I guess it will be not up to date with latest imgui

[GeTechG]

Just LOVE2D is assembled with LuaJIT

[GeTechG]

I was able to run your implementation in LOVE2D by copying the libraries to LOVE2D. And I put https://github.com/Jarodwr/love-imgui-wip, but alas, it didn't work. Thank you for trying to help me, I think you can close the issue. Next, if the author builds for linux, it'll be great.
