compilation error : multiple definition of `mem_init'

[wdmomoxx]

I don't know what went wrong. The compilation tips are as follows

Can you help me

Hi, I seem to be having the same issue.

From what I can tell, it's something to do with declaring the variable in both the header and the C++ file. But I don't know how to fix it.

Were you able to solve the problem?

I ended up just renaming the function to "mem_init2" and went through the following files to adjust it: gameboy.ino, main.cpp, mem.cpp, mem.h. I was able to compile it afterwards.

Can you explain the changes you have made ?

Just find and replace mem_init to mem_init2 in these 4 files; gameboy.ino, main.cpp, mem.cpp, mem.h.

Its as simple as that
