Building arGecko: need help

[lightwo]

I can't manage to build arGecko. It appears to be the only Aroma plugin that enables using cheats on the system (e.g. working around broken games).

I built and installed wups and wums (make install), but for some reason, arGecko's Makefile refers to nonexisting $(WUMS_ROOT)/share/libkernel.ld.

Given that I am not a Wii U developer, nor have I ever used devkitPro beyond building existing projects, can you please help out?


Error log:

main.cpp
arGecko/source/main.cpp:3:10: fatal error: kernel/kernel.h: No such file or directory
    3 | #include <kernel/kernel.h>
      |          ^~~~~~~~~~~~~~~~~

That's it! Thank you so much!

I wish that arGecko had a list of build requirements in readme, but either way, that did the trick.

I'm not sure if I should make a separate thread, but after analysing code (there is absolutely no documentation), I got the impression I'm supposed to do this:

1. Make sd:/wiiu/gecko/0005000012345678 (title ID)
2. Put cheats as separate files with the .gko extension

The cheats are presumably files with no comments or anything, just addresses and values:

30000000 12345678
D0000000 DEADCAFE

The problem is that I tried a cheat and it didn't appear to do anything. Since it doesn't appear to have remote functionality, JGecko U is a dud. I couldn't find where it stores logs, so I'm completely lost now.

@QuarkTheAwesome Mind chiming in?

Update: I contacted Quark, and it looks like I did everything right, except this only works with codes that execute assembly (equivalent to "Execute ASM" (C0)). For all other codes, can't use utilities compatible with Aroma, only Tiramisu.
