Hi Tim,
I have a project I have been developing for several years now,  with several builds that share some code.  I was using Arduino libraries, but it seemed to me a better solution in my situation would be local libraries.  I recently made a couple of small changes to a library and wanted to check it with a previous example sketch I had written for that purpose.  I found that the example sketch, now moved to:
<sketchbook>\<sketch>\_micro-api\libraries\<lib>\Examples\demo\ demo.ino

compiles but gives me the following linker errors:

ccPch99Z.ltrans0.ltrans.o*: In function main
main.cpp:43: undefined reference to setup
main.cpp:46: undefined reference to loop

The same sketch in the original location:
<sketchbook>\libraries\<lib>\Examples\demo\ demo.ino

compiles and runs fine.  The contents of the two locations (i.e., below _micro-api\libraries and below the sketchbook libraries folder ) are identical, and of course there are loop() and setup() functions.

I can send you further info, but before that, is there a simple answer - like "not supported", or some project setting?  I can't immediately see any reason why this doesn't work, so suggestions welcomed.

Regards,
Jed
