Linux Mint compilation issue: FAILED: libcommon.fa.p/hw_intc_pl192.c.o

[adespoton]

I'm not completely sure why this is killing the entire build chain, especially since I don't think the intc_pl192 hardware is even used for the iPod Touch virtual device. Should that just be commented out of the initial configure? It seems like WErrors are enabled and certain warnings are triggering in the code, causing a hard fail.

We get "cc1: all warnings being treated as errors" -- this suggests that WError is being set somewhere in one of the makefiles.

Meanwhile, we should probably update the code to handle all those unused variables and make the fallthrough explicit?

Full error and context below:

I can probably hack this to a successful build for myself, but figured I should flag it so we can fix the warnings and handle the warning failures appropriately for a clean configure/make.

same error, been trying this in WSL for like 2 hours now? and using find yeilds no results in either directory, very odd.

if you do fix it can you post your solution?
