not able to build project using sgdk/skeleton #34

Hi, I created a "hello world" project by copying sgdk/skeleton content and not able to build it:

Hi, I was able to progress, fixed above issues by including extra paths in INC and LIB, in the skeleton Makefile; plus I added this line to "sgdk/Makefile" to solve the "sgdk.ld" issue, just at the end of the "install" target:

        cp files/sgdk.ld $(GENDEV)/ldscripts/.

I can create a PR for these if needed. Now hit another issue and dunno how to progress, looks like it's still missing some symbols?

Sorry I completed missed the point on the README to build the SGDK project; so I was using the wrong makefile. Using it works like a charm. Is there a reason then to have that sgdk/skeleton?

In any case this can be closed. Cheers

No worries. You are probably right that the sgdk/skeleton dir may no longer be useful (or perhaps counter productive). I've been attempting to clean this project up a bit, and likely have more to do!

@kubilus1 hi, I would be more than happy to help, just need to get rid of the rust and get more and more in low-level . If you have specific things to focus on I may give it a chance
