Here is how I build: ~/Arduino/Testy_App/$ arduino-cli compile -library "/home/davis/Arduino/Testy_app/foo/" -fqbn arduino:samd:mkrwan1310 Testy_app Visually this is the directory layout ~/Arduino/Testy_app/ <- sketch dir which, after symlinking to libraries, would force MyPdeSketch to show under the examples for the MyLibClass library in Arduino IDE (however, it may not be applicable if you want to self-contain multiple class folders under a single directory).ĮDIT: or just use a Makefile - which would work directly with avr-gcc, bypassing the Arduino IDE (in which case, the sketchbook file organization can be somewhat loosened). path/to/skdir/MyLibClass/MyPdeSketch/MyPdeSketch.pde For the same reason, symlinking to the alternate location ~/sketchbook/libraries could also be problematic.įinally, a possibly better organization could be: /path/to/skdir/MyLibClass/MyLibClass.cpp Otherwise, it should also be possible to symlink the MyLibClass directory directly into arduino-0022/libraries (instead of manually making a directory, and then symlinking the files). Note that the only way I can see so far for a library class file to refer to other library files is to include them relatively (from 'current location'), assuming they are all in the same main arduino-0022/libraries folder (possibly related Stack Overflow question: Is it possible to include a library from another library using the Arduino IDE?). Ln -s /path/to/skdir/MyPdeSketch/MyLibClass/MyLibClass.* /path/to/arduino-0022/libraries/MyLibClass/Īfter restart of the IDE, MyLibClass should show under ''Sketch/Import Library''. What worked for me is something like: mkdir /path/to/arduino-0022/libraries/MyLibClass (In principle, /path/to/skdir/ here is equivalent to ~/sketchbook/) path/to/skdir/MyPdeSketch/MyLibClass/MyLibClass.h path/to/skdir/MyPdeSketch/MyLibClass/MyLibClass.cpp I just had this same problem (I also like to keep the code self-contained), so I'll just jot down some notes say I have a MyPdeSketch.pde using MyLibClass.cpp then I have it organized like this /path/to/skdir/MyPdeSketch/MyPdeSketch.pde This requires that you run make after editing your files, but since I'm using an external editor (Emacs) anyway, this is zero hassle for me. I use a similar trick also to put together JavaScript files here. h - so this is about the only way to do it. cc file in its directory it automatically uses it in the source, and you can't include anything that's not a. $(PREPROCESS) $< -o is very picky about file endings - if you put a. cpp sources - you can see this used in this Makefile: PREPROCESS=gcc -E -C -x c -iquote. To get around this, I use make to put together a single. I agree with you this is an intolerable way to develop software: it requires every file that you need to be in the same directory as the main program! Is this possible? And, if so, how do I include them in the main file for building? Preferably in their own subdirectories. I've also tried adding the libraries to the sketch directory in subdirectories (what I would greatly prefer) and then linking to them as: #include "mylib/mylib.h"īut both of these result in file not found errors. don't even care if they should up in the arduino IDE. I've tried adding the header files to the sketch as a new tab, but that doesn't seem to work at all. Also, just for the sake of being able to easily zip of the sketch folder and know that it contains everything it needs. However, I have tried to place the libraries in the same directory as the main PDE file so that I can more easily keep everything synced up in subversion (I work on this on multiple computers) and I don't want to have to keep going back and syncing up the libraries separately. Multiple libraries were found for "Adafruit_BMP280.h"Ĭ:\Program Files (x86)\Arduino\libraries\Adafruit_BMP280/Adafruit_BMP280.h:25:29: fatal error: Adafruit_Sensor.I know that you are supposed to place any external libraries under the "libraries" folder of the arduino install directory, but I have a project that uses several libraries that I have created for the project and mainly to keep all that code self contained and out of the main pde file. In file included from C:\ArduinoFiles19\JWSerialRX1Teens圓5\JWSerialRX1T eens圓5.ino:8:0: The compile errors are as attached below: I needed some advice from the forum regarding these directories because I do not know if removing them will cause other difficulties. One of which is in the hardware\Teensy\etc folder. I have three Arduino libraries, one in my user folder, two in my c:\program files x86\Arduino folder My query to you was regarding the directory structure. I have solved the compile problem myself because the sensor.h file (among others) was missing, probably deleted during the installation of the updated IDE.
