![]() There are some options where additional library folders could possibly be added? E.g. In the build folder a file `` is generated automatically. So there could be some option for this to be set in the ino file.Ģ. But this has to be done manually and changed every time another program is handled. As a workaround in the preferences the sketchbook location can be set to the folder of the own program. I don't have insight into the Arduino IDE, but identified two possible points:ġ. As an example there are major changes to the API of the very popular ArduinoJson library in version 6. freeze libraries at a working state or apply little modifications to standard libraries. There are obvious benefits for developers, e.g. ![]() There are many more or less useless forum discussions in the web about how to ha … ndle libraries in the sketch folder, but this only works for simple header files and according cpp, but not for more complex Arduino libraries like WiFi101. It will likely be here, as that was the relevant issue tracker up until 5 years ago: GitHub There will definitely be some interesting discussion there, so I recommend you to check it out and comment if you have anything original and productive to add. There definitely is one, but I don't have time to search it out right now. I think I'm going to open an issue about this, if there isn't one already. The Arduino sketch specification might also provide some useful information. If you enable File > Preferences > Show verbose output during: compilation and then check the contents of the black console pane at the bottom of the Arduino IDE window after compiling, you can see the location of the temporary build folder and check out the contents.Īnd any other "gotchas" with the environment? So the code that is compiled is different from the code in the original folder. ino files of a sketch to make them a valid C++ file before compiling, as described here. The reason for compiling the sketch in a temporary directory rather than in place is that, to make things easier for beginners, a couple things are automatically done to the. So as far as saying "library", that is only correct when it's a header-only library, which are relatively rare.ĭo you know of any documentation or discussions that explain why this is the case It's true that you can provide the full path name to a header file, but this will not cause the source files in that path to be compiled, as is done when you only provide a header file name in the #include directive without a path. You need to provide the full path name if the library is not in the same folder as your. Right now it feels like I might be just moving to WinAVR etc, but the jump to there from working Arduino code seems like it could be challenging. The error is identical in both so I was pegging it to the avr-gcc compiler and not the IDE specifically. I wanted to see if it would work in the official IDE before making a post. I actually ran into this trying to get this working with VS Code, as I'm trying to get away from the Arduino IDE and all it's limitations. I don't use the IDE for editing my Arduino programs - I use the Geany editor for all my programming. Yeah I get that and have heard this sort of argument regarding the Arduino IDE already, my retort is always the same though: Supporting "complex" features doesn't have to detract from the simplicity of the overall system. The Arduino IDE is designed to be easy for a complete newbie to use and my guess is that the way it is implemented "seemed like a good idea at the time" - after all, who would expect newbies to understand relative paths The project runs into the same error with the Arduino IDE and VS Code, so I think it has something to do with the avr-gcc flags, so maybe I can fix it somehow with a change to platform.txt? I use the same include in the c++ RPi project (in the "server" directory) without issue.įull disclosure: I'm trying to switch to VS Code since the Arduino IDE is very basic/immature, so I'm looking for a solution that doesn't involve changing IDE settings - since those probably won't carry over. the current working directory or anything like that. It's always been my understanding that relative paths in double-quoted include directories are interpreted as being relative to the source file in question, not e.g. includes/myfile.h: No such file or directory ' #include ' to ' #include "./includes/myfile.h"' and while this is perfectly valid C/C++, the arduino compiler doesn't like it and complains about not being able to find the file. I then changed the include for my header from e.g. I moved all the code into a single project directory with three subdirs: "server", "client", and "includes" and copied my sketch into the "client" dir. I'm trying to restructure my project and get everything in git, especially the custom headers I share between my Arduino & RPi code.
