Issues building bootloader under Unix

[Ardenryst]

The Makefile responsible for building optiboot uses quotes around the avr-objdump command (line 121). This causes issues when the path contains an~, the alias for the user home folder on Unix systems. Not sure why this part is put in quotes, since the other commands for copy and size are not. The original Makefile of the optiboot project has the line $(call fixpath,$(GCCROOT)avr-objdump) here instead, but this doesn't work either (though the resulting error is different).
Propably this special treatment may have something to do with Windows? Unfortunately I cannot test that for lack of such a system.

Could you specify what makefile you're looking at from within this repository? I had a look at the Optiboot makefile and line 212 is not related to avr-objdump:

Please excuse, my bad. I corrected the line number.

All good! Thank you for the clarification. That is odd that only that lines has quotes around it. And I'm assuming simply removing the double quotes from that line doesn't change anything?

[Ardenryst]

For my setup removing the quotes solves the problem. I supose there is a reason for them being there of course, but I'm not sure what that is. Propably some other OS related issues?
The file differs here from the original optiboot project (https://github.com/Optiboot/optiboot/blob/master/optiboot/bootloaders/optiboot/Makefile#L141) in this location.

I have no idea, I can't make sense of makefiles!

You think I'm some kind of rocket surgeon?!

Weird. The original optiboot (which doesn't have dx support) does not have those quotes...
