How to include/use Arduino's standard libraries?

[ncolomer]

Hello,

Referring to a previous comment here, I still face a problem when I want to include an Arduino standard library, in my case, Arduino's EEPROM.h library.

I figured out that the library files are present in the platformio path ~/.platformio/packages/framework-arduinoavr/libraries/EEPROM/EEPROM.h. I imagine they've been downloaded while installing the atmelavr platform.

How to include and use those standard libs correctly?
I expected something simple as with the Arduino IDE where we only need to add #include <EEPROM.h>

I'm using the latest platformio stable version 1.4.0 with Eclipse CDT IDE.
My platformio.ini file looks the following:

[env:prototype]
platform = atmelavr
framework = arduino
board = nanoatmega328
build_flags = -DDEBUG -Llib
#upload_port = /dev/cu.wchusbserial1410
#targets = upload

Hi @ncolomer!
Simple include like #include <EEPROM.h> should be enough.
Maybe you can provide build log or a simple project?

Hi @valeros
Actually, it seems that the include only runs when it is written in the main.cpp file.
When I do the include in another (header) file, the following error appear:

$ platformio run

^
compilation terminated.
scons: *** [.pioenvs/dev/src/DeviceID.o] Error 1

Thus, a workaround should be to do all the includes in the main file (to explicitly tell platformio to add the libraries in the build I imagine), and repeat them in my headers/implem files, WDYT?

[ivankravets]

PlatformIO scans for includes all source files "*.c, *.cpp, *.h". It should work for you.

Could I ask you to share a simple project where I can reproduce this issue?

Thanks in advance!

With best regards, Ivan Kravets

Hi @ivankravets :)
Sure, you can download the zipfile of the project directly from here. Then, simply (un)comment the #include <EEPROM.h> line in the main.cpp file and run platformio run to see the problem.
Cheers,
Nicolas

[ivankravets]

Thanks! This bug is fixed in the latest develop branch. You can try it via http://docs.platformio.org/en/latest/installation.html#development-version

P.S; I'm going to release 1.5.0 this week, where this issue will be fixed.

[ivankravets]

This is a duplicate of #189

[ncolomer]

Great! Thanks a lot @ivankravets @valeros :)

[Jeppedy]

Is it broken again in 1.6.5? I have the exact same issue, with the exact same fix... If I include the #include in my main ino file, all works fine. I don't reference anything from that header, but I have to include it.
I only actually reference that header in a library (some cpp file elsewhere) that is USED in my sketch.
Sounds like the exact same problem...

Thoughts?

[ivankravets]

@Jeppedy please provide the problem project to reproduce this issue

[evanlooij]

Same problem here, using embedXcode and Xcode to compile a sketch agains Arduino IDE 1.6.7.
#include <EEPROM.h> leads to

error: eeprom.h: No such file or directory

#include <avr/eeprom.h>
does allow one to use the AVR functions, i.e. eprom_read_byte (docs at avr-libc)

[ivankravets]

@evanlooij please use platformio tool for compilation

[tdehaeze]

Same issue, I use the platformio CLI to compile and flash.

When I write #include <EEPROM.h> in any .cpp file expect main.cpp it throws an error when I run platformio run : fatal error: EEPROM.h: No such file or directory.

Same for my own libraries, I have to include them all in my main.cpp file in order to work.

[tdehaeze]

After some research, it's finally working using this fix (enable deep search for dependent libraries)
Thanks

[mintisan]

@tdehaeze I also encounter this issue. Can you show me how to fix it with a platformio.ini example?

Thank you.

[bitflogger]

IDE 1.71, Core 3.2.1, on Windows 7, I have a similar issue, i managed to replicate it. My issue was that I created a file in my project called 'eeprom.h', which I included like this: '#include "eeprom.h"'.
Once I renamed the eeprom.h I saw no issues anymore.

Having said this, I would like to stipulate that this issue is not seen on my linux, command-line box!

[ivankravets]

@tdehaeze , @mintisan , @bitflogger could you provide a project example to reproduce this issue?

[noisymime]

I'm seeing exactly the same issue with including EEPROM.h
Have tried with and without the deep search option and it appeared to make no difference (Assuming I've enabled it correctly).

Copy of the project is attached and this compiles fine in the Arduino IDE.
speeduino copy.zip

The file /Users/josh/.platformio/packages/framework-arduinoavr/libraries/EEPROM/src/EEPROM.h does exist and is readable by platform io

[ivankravets]

@noisymime please add lib_deps = EEPROM to [env:teensy35].

[noisymime]

@ivankravets Thanks Ivan, that fixed it (Needed to be added to [env:megaatmega2560] as well)
