Sort of. I did know about that and I did copy the blank main.cpp from the example test into ~/libmaple and I thought I'd double checked it.

However, all object files have to be linked in every time, maybe it's that what you're referring to?</p> <p>Maybe it'd help if you'd post the console outputs of your build process somewhere to shed some light on what where make may go wrong on your side.

Before I did the libmaple upgrade as stated a few posts back, it would compile all of the libmaple stuff once the first time, then after that it wold only compile any files that had changed (usually just my project files), at least until I did a make clean. This is how makefiles are supposed to work.</p> <p>Post upgrade, once I finally got the Makefile to compile all of my files and not just main.cpp, it compiles all of libmaple every time. </p> http://forums.leaflabs.com/topic.php?id=1008&page=3#post-23112 Sat, 23 Mar 2013 05:08:36 +0000 ventosus 23112@http://forums.leaflabs.com/ <p>Use ccache to speed things up as described here: <a href="http://leaflabs.com/2012/08/2549" rel="nofollow">http://leaflabs.com/2012/08/2549</a> </p> http://forums.leaflabs.com/topic.php?id=1008&page=3#post-23046 Fri, 22 Mar 2013 20:59:20 +0000 tdc218 23046@http://forums.leaflabs.com/ <p>Got it working, sort of.

Ok, getting back to this a year later.

Stop.<br /> <code>blockquote</code></p> <p>I've confirmed that maple_nini.mk exists at ~/libmaple/support/make/board-includes/ but obviously it's not finding it. How do I fix this please and thank you?</p> <p>ps - I apologize if bumping a year old thread is a breach of netiquette in these parts. It seemed the most logical place and the guidelines are silent on this issue. </p>
