That is how make works.</p> <p>Martin - So, the information that is missing is how to add your own source files to the Makefile set?<br /> Earlier in this thread the discussion mentions build-targets.mk which should include a list of the source files you need to be included in the final binary. The rues in the other makefiles will work out how to convert from source files for you. </p> http://forums.leaflabs.com/topic.php?id=697#post-5825 Mon, 01 Aug 2011 08:57:10 +0000 robodude666 5825@http://forums.leaflabs.com/ <p>For my projects, I modified the make and build-target files to compile my other project files instead of using the library.</p> <p>I am using something similar to the <a href="https://github.com/Ixox/preen/blob/master/Makefile">PreenFM</a> project.</p> <p>It would be nice, however, to see some documentation on how to build the library once and link your project against it - for those of us less familiar with Makefiles. </p> http://forums.leaflabs.com/topic.php?id=697#post-5818 Sun, 31 Jul 2011 09:30:06 +0000 Martin 5818@http://forums.leaflabs.com/ <p>Sorry to open again this old thread, but i'm facing the same issue as augustl. I installed the unix-toolchain as in perry's link and played with the example and wrote my own code and everything is fine.</p> <p>I also built the static library using 'make library'. Now i'd like to continue my own project and link it to libmaple.a. What is missing is an example Makefile to build a project with multiple source file which are not in libmaple's directory and link it to libmaple.a and upload it to the device.</p> <p>Playing with main.cpp in libmaple's directory is fun to start and get used to the maple board but not really suits bigger projects. </p> http://forums.leaflabs.com/topic.php?id=697#post-4037 Fri, 25 Mar 2011 13:31:38 +0000 mbolivar 4037@http://forums.leaflabs.com/ <p>augustl,</p> <p>yup, as snigelen says, the link perry posted has pretty detailed answers for exactly those questions.</p> <p>other files involved in the build chain are libmaple/libmaple/rules.mk and libmaple/wirish/rules.mk.</p> <p>each of the individual libraries (in the subdirectories under libmaple/libraries) also has its own rules.mk file.</p> <p>you don't really need to understand these details; mostly, just read the tutorial perry linked and be aware that build-targets.mk has the rule to build main. also check out the "library" top-level Makefile target if you want to build libmaple as a static archive to link against. </p> http://forums.leaflabs.com/topic.php?id=697#post-4026 Fri, 25 Mar 2011 03:22:33 +0000 snigelen 4026@http://forums.leaflabs.com/ <p>Hi,</p> <p>Did you click on the link perry posted?</p> <p><code>make</code> will build your program<br /> <code>make install</code> will upload it</p> <p><code>make V=1</code> will show the full command line of every command executed by make (for libmaple, not in general).

They are typed on the command line when you run make.</p> <p>For example, this lists common make options:<br /> <a href="http://unixhelp.ed.ac.uk/CGI/man-cgi?make" rel="nofollow">http://unixhelp.ed.ac.uk/CGI/man-cgi?make</a></p> <p>The options: <li> -d Print debugging information in addition to normal processing.<br /> -n, --just-print, --dry-run, --recon Print the commands that would be executed, but do not execute them. </li> <p>There is also<br /> --debug[=FLAGS]<br /> which can be used to control how much information is printed. </p> http://forums.leaflabs.com/topic.php?id=697#post-3999 Tue, 22 Mar 2011 17:48:17 +0000 StephenFromNYC 3999@http://forums.leaflabs.com/ <p>Hello augustl,</p> <p>Welcome to the Maple. I think the next year will be very exciting, with the arrival of the new IDE and the new boards, and with new users who want to learn the details. Eventually, I may become more interested in this level of detail, but in the near future I will be more focused on contributing and testing new features (in particular DMA coupled to isochronous USB data transfers using double-buffers; I think that is possible).</p> <p>Is there any guide from Arduino-land which has the right amount of "behind the scene" explanations which will make you happy? This might result in an improved answer from a user or at least a "that is something which we have on our to do list" answer from the leaflabs crew.</p> <p>Of even better, one of the maple/arduino linux code sourcery gurus might be able to take an Arduino guide which you like and quickly translate it it into something for the Maple.</p> <p>A few months ago there were some topics related to compiler optimizations settings. Is this the info which you want?</p> <p>On a more practical note, I understand that you do not want to use the IDE. However, were you able to compile and upload any sketches using the unix-toolchain or the IDE? This will at least you that everything is installed in the expected places.</p> <p>I have not tried to add content to the wiki, but I am looking forward to your contributions.</p> <p>Good luck-</p> <p><a href="http://forums.leaflabs.com/profile.php?id=843">Stephen from NYC</a> (full disclosure: I am not a member of the LeafLabs staff) </p> http://forums.leaflabs.com/topic.php?id=697#post-3998 Tue, 22 Mar 2011 14:38:43 +0000 augustl 3998@http://forums.leaflabs.com/ <p>Thanks!</p> <p>But it doesn't seem to help me understand what's going on, though.
