Good morning. Either I’m missing something or… the development version is still 2.11. So how to install?

[ivankravets]

How did you install development version?

[andig]

As the docs day:

# uninstall existing version
pip uninstall platformio

# install the latest development version of PlatformIO
pip install -U https://github.com/platformio/platformio/archive/develop.zip

Do you use PlatformIO IDE Terminal?

[Robert_Walli]

Hi!

I’ve tested 3.0 on macOS with platformio-ide and command line.
The command line installation works only as root (sudo).
To switch back to the ide-version i had to uncheck the “Use Development version…” and click it again.

Tested a lot of projects (atmelavr and espressif) and all works perfect.
Switching different version of global libs works as well.

For the sake of completeness i should mention a cosmetic flaw:
The first line of compilation is always:
"Warning! Ignore unknown envs_dir option from [platformio] section"
Which isn’t true because envs_dir option is not ignored.

Thanks a lot for the report!

@Robert_Walli

Thanks, I’ve just fixed it

Fix typo with known default options for [platformio] section

[Robert_Walli]

I forgot that “pio run -t clean” also did not work in my case…

@Robert_Walli

What do you mean? Try

pio run
pio run -t clean

What do you see?

[Robert_Walli]

eg. the blink example:

pio --version
PlatformIO, version 3.0.0a4

pio run -t clean -e uno
[Wed Aug 10 19:42:24 2016] Processing uno (platform: atmelavr, board: uno, framework: arduino)

Collected 35 compatible libraries
Looking for dependencies…
Project does not have dependencies
================== [SUCCESS] Took 0.61 seconds ==================

ls /tmp/pio/blink/uno/src/
Blink.o

ls /tmp/pio/blink/uno/
FrameworkArduino firmware.hex libFrameworkArduinoVariant.a
firmware.elf libFrameworkArduino.a src

guess these files should not be there…

Robert

[ivankravets]

Could try the same with -v option?

pio run -t clean -e uno -v

[Robert_Walli]

the same…

pio run -t clean -e uno -v
[Wed Aug 10 20:16:01 2016] Processing uno (platform: atmelavr, board: uno, framework: arduino)

Collected 35 compatible libraries
Looking for dependencies…

[ivankravets]

I can’t reproduce this issue Could you try to remove .pioenvs directory manually and try again?

[Robert_Walli]

I figured out that this only happens with envs_dir set.

e.g.:
[platformio]
envs_dir = /tmp/pio/blink

can you reproduce this?

Robert

[ivankravets]

This is a bug. Please report it here Issues · platformio/platformio-core · GitHub

@ivankravets

Do you use PlatformIO IDE Terminal?

No, I had actually done this through the normal terminal. Working now when run through IDE- thanks!

[andig]

One thing I notice is that the builds have become slower. Previously, I was using the packaged libraries. With 3.0 I can refer to git repos instead:

; lib_install = 1,19,31,54,64,306,346
lib_deps =
  OneWire
  Adafruit-DHT
  Adafruit-Unified-Sensor
  DallasTemperature
  Json
  me-no-dev/ESPAsyncTCP
  me-no-dev/ESPAsyncWebServer
  marvinroger/async-mqtt-client

When I do this I notice that the (re)compile times almost double for my project from 2.7 to 4.7 seconds.

Maybe the builder recompiles the git libraries instead of relying on compiled objects?Other ideas for possible causes?

I can successfully install pio 3.0.0a6, but when I try to build, i get the following errors:
