Core files should be compiled in a subdirectory

[NicoHood]

I'll explain the issue with an example (ide 1.6.3, win8):

Install the HID project into /sketchbook/hardware/HID
https://github.com/NicoHood/HID

Restart the IDE
Now select the new board that pops up under tools/boards/leonardo HID Project

Type Consumer.begin() in the empty sketchs setup()
compile the code (Control + R) -> Works fine

Now open the example via File>Sketchbook>hardware>HID>HID>Consumer
It wont compile.

I've tested:

• Add an #error to the Consumer.cpp file -> recognized correct
• Include the file via #include "USB-Core/Consumer.cpp" -> compiling correct.

It seems that the files are not linked correct, maybe due to a subfolder?

The error occurs when:

• Open the example via double click
• Open it via file

It does not occur if you:

• Paste the Code into the window that is opened by the startup
• Or the windows that is generated by a "new sketch" button press

It does not matter which Board was selected at closing.

Temporary workaround for 3rd party developers
Open the examples, mark everything (Ctrl + A) and paste it into a new sketch (Ctrl + V)

Weird bug. You should probably include the full compiler output here as well?

Sketch uses 4,634 bytes (16%) of program storage space. Maximum is 28,672 bytes.
Global variables use 135 bytes (5%) of dynamic memory, leaving 2,425 bytes for local variables. Maximum is 2,560 bytes.

The problem is in the Consumer.ino filename. This results in a compiled Consumer.cpp.o file, directly inside the tmp directory. However, the Consumer.cpp file from the core is also compiled to the same Consumer.cpp.o file.

Having the .o filenames conflict in this way should be fixed in the IDE. I think the core files should be compiled inside a subfolder of the tmp folder ("core", or perhaps named after the core itself). This would reduce the potential for conflicts, only when you have a library called "core" this could still conflict. To fix that, a library should be compiled inside a tmp/libraries/name_of_library folder perhaps.

Also interesting is that any subdirectories in the core directory are lost. cpp files in subdirectories are compiled, but the .o path doesn't contain the subdirectory anymore. So if the same filename occurs in the core twice (in different (sub)folders), this would again conflict.

Thx! And I've noted it somewhere in my Documentation to not do this. X_x

Thanks!

Ergo: Someone should add a patch to check the filename vs any compiled cpp?

Also note that this is not specific to 3rd party cores - If I create a Print.ino sketch, I expect the IDE will break using the normal Arduino core as well.

I was wondering if this problem would ever come up.... been watching for it for years!

ACK. Solving this will also help solving #1337 as we'll be able to copy sketch source files into temp dir.
