library not found in deviot; platformio command line works

[jwhendy]

This may be similar to #18 . I started playing with the teensy audio library + leds, and am using the following in my sketch:

#include <FastLED.h>
#include <SD.h>
#include <SPI.h>
#include <Wire.h>
#include <Audio.h>

From subl3 + deviot, I get errors for missing header libraries, but via platformio directly, it works fine. Here's the deviot output:

For my directory structure, here's what I have:

From previous work with deviot, it seems it can find the library somehow (looking in the main ~/Arduino/libraries folder?), but platformio wants them in lib, so I just symlink to what I want to bring in (hence, Audio just points to the version in the main Arduino folder). I have my main .ino file in the top-level directory but symlink to it in src to make platformio happy from the command line.

Let me know if you have any insights. This is on arch linux.

Since Platformio 3 is possible to add an extra folder to find other libraries.

The develop branch has that option already implemented, follow this steps to manually install it:

• Download this files (from the develop branch) and replace with the file in the Packages/Deviot
• Remove Main.sublime-menu in the same folder to get the new changes in the menu
• Restart ST

Now you can select an extra folder in Deviot Menu > Library Options > Add Extra Library Folder

Let me know if that solves your problem

[jwhendy]

I'll give this a try but am still a little confused. Is Deviot purely (mainly?) a sublime front end to platformio? I ask since platformio doesn't require me to specify another library folder, or at least symlinking to a needed library in lib/ seems to work.

What are the mechanics of what I'm doing by telling Deviot about an additional library folder? Is this applying a change to platformio behind the scenes or to Deviot?

Sorry for being confused. I'm not super familiar with the inner workings of any of this so it helps to have a gist of what's going on through these steps.

Thanks!

Yes, Deviot is mainly a fron't end plugin wich handle PlatformIO, there some cases where Deviot make some thing automatically and in platformio need to do manually

for example, the feature to add a new folder where you have all your libraries need to be done manually in the platformio.ini file (http://docs.platformio.org/en/stable/projectconf.html#lib-dir), but Deviot do automatically in each file you are working on.

I think I missed something from your first message, now I understand, if you compile you code directly from platformio it do it without problem but from deviot show missing library. The answer is, it shouldn't shown that erros.

Are you using the same folder structure to compile in Deviot? some days ago someone tell me about the same error but it was because he has more than one file in the same folder, normally platformio compile all inside the src folder. Deviot can compile that way or using the src_dir option wich override the src folder.

Can you add the structure of your folders to try to replicate the issue (including the libraries)

[jwhendy]

Gotcha, and correct -- it works in platformio, but not in Deviot. Do you need more than what I posted above? I ended with the output of ls -lR, which shows that I have src containing a symlink to the top level .ino file (in case Deviot needed to look in the top-level), and a symlink to the teensy Audio library inside lib. That's it.

Give me a bit and I'll create a reproducible example, though all I'm going to do is make a new dir, a .ino file with includes and empty setup() and loop(), and git pull a fresh Audio teensy copy. This is the first library that's complained and the behavior is not clear to me. Some libraries work as-is, others (like FastLED require symlinking into lib, so I'm not sure where platformio is looking for things...

[jwhendy]

Further development... I looked at the output of ps ax | grep subl when deviot was hung trying to upload and see this:

/home/jwhendy/.config/sublime-text-3/Packages/User/Deviot/penv/bin/python /home/jwhendy/.config/sublime-text-3/Packages/User/Deviot/penv/bin/platformio -f -c sublimetext run -t upload -e teensy31

I wondered if the platformio bin used was different than my own, so I tried using yours directly vs. what I have from the Arch platformio package (/usr/bin/platformio). This works fine:

/home/jwhendy/.config/sublime-text-3/Packages/User/Deviot/penv/bin/platformio run -t upload

I can run that whole line (including the call to .config/.../python before it) as well.

Why would that be? What subl3 appears to be calling in the background while trying to upload works directly, but not from within subl3? Hope that adds more information that can help track things down.

This is fixed in Deviot 2.

If you keep with this problem reopen this issue

[jwhendy]

I can't seem to open this, but it's probably not necessary. This is just to help anyone else who comes across confusion about this. I think there were a couple things going on:

• I thought I had instances where platformio could find included libraries without me doing anything. It's been a while, so I'm not trusting my memory. That said, there is support that this works
• regardless of which case was going on above, I definitely didn't understand how platformio worked with respect to libraries. My solution was to ln -s ~/Arduino/libraries/desired-lib ./lib/desired-lib from inside my sketch folder
• from reading the docs, I now believe this should be done via platformio.ini and adding the lib_extra_dirs option.
• now that I realized that, I finally understand the comment above about Deviot -> Library options -> Add extra library folder!

So... we're all good for the most part. I think my comments in #154 stand though. It seems that you're re-creating what platformio already does, but in /tmp. I'm a hobby programmer, so I often just copy and paste my own code/files when I start on a new project as I re-use the includes. With platformio directly, I can do his no problem as my options from platformio.ini are carried over. With Deviot, it appears I have to reset the board, environment, and extra libraries because they stay in /tmp vs. with my project dir...

Anyway, thanks for your patience/persistence with me! I think there's room for improvement, but now very much believe this issue was my total mis-understanding!
