OS is Zorin OS (Ubuntu based)
This is way above my head. I have no idea how to debug something this complex.
Web searches aren't helpful.

Here is more of the error as it appears on Mint:

Whoops, all fixed in 01e7529. The XPLAINBridge project uses some sources from the AVRISP project, but I was compiling in the ISP programming protocol code which isn't needed, and which uses an interrupt vector internally that the XPLAINBridge project uses for other purposes.

Since the XPLAINBridge project doesn't use the ISP protocol compiling in the module isn't needed, and only results in the linker conflicts you're seeing there from the duplicate interrupt handler definition.

Thanks will checkout

Ok, finally got around to doing a test compile, and apparently XPLAINBridge is still referencing the ISP protocol for some reason. Here's what happens:

Did you perform a make clean beforehand, and pull the latest code? Your link step still refers to ISPProtocol.o which should no longer be a prerequisite of the ELF build target.

Bug confirmed. Same problem here.
