Weird lib problem about arduino-makefile

[sudar]

Can you also post your sketch, either as a gist or in pastebin?

Also the SPI library you are using is the build in one? And which Arduino version you are using?

[bradwood]

Hi.

THe SPI lib is the standard one, not one in my USER LIB folder. Arduino version is 1.0.5.

Sketch is here: http://pastebin.com/eNp2xFxD

Thanks

Brad

I'm getting this too on Debian with 1.0.5 (and arduino-mk 0.10-5) it seems sometime after 0.10-2 the libs folder isn't being created within the build-uno directory.

I assume its because DEP_FILE is no longer being used (commit 4fdd176) it only seems to affect system libs - same as Brad has with his SPI lib.

I recently also noticed this. I suspect that one of my commits caused it, I'll see how we can fix this properly.

@matthijskooijman

Some more hints for debugging.

I guess this happens when the library folder has more than one *.cpp file.

I have a suspicion its 1.0.5-specific, in particular all the Arduino Robot libs that come with 1.0.5 seem buggy as all hell... Not sure if it's trying (and failing) to build these too...

[sej7278]

The 1.0.5 wifi libs have been a headache too, but I don't think that's the problem

[sudar]

I have a suspicion its 1.0.5-specific

I am able to reproduce this even in Arduino 1.0.3. So I guess this is because of the change in dependency code and not Arduino.

[matthijskooijman]

Here's a fix. Not as pretty as I would have liked, but Makefiles really are too limited in certain ways, it seems.
