PIO Upgrade generates error "'isnan' has not been declared"

#1

I have been trying on and off for months to install platformio on my Mac so I can build this project https://github.com/esprfid/esp-rfid

After some help from platformio I managed to dothis last week, I had too many versions of python installed.

I download the code and built it nut it generated these errors,
/home/pi/.platformio/packages/framework-arduinoespressif8266@2.20502.0/cores/esp8266/Arduino.h:270:12: error: ‘isinf’ has not been declared in ‘std’
270 | using std::isinf;

I then realised I could install platform io CLI on my raspberry PI 4, which I did and the project built with no errors.

Then I ran this command “pio upgrade” and this package was updated
Updating platformio/toolchain-xtensa 2.40802.200502 @ <3 [Updating to 2.100100.200706]
Tool Manager: Installing platformio/toolchain-xtensa @ 2.100100.200706

Now when I build the project I get the same errors as per my MAC.

So my question is, have I found a bug or more likely as I am a newcomer to platformio is there something wrong with my setup?

Can I roll back to the previous version on both my PI and preferable my MAC so I can use VScode editor?

Is there something else I can do to investigate the problem?

The platformio.ini in the “dev” branch actually seems more sensible than that in the stable / main branch, since it fixes the version of the Espressif8266 platform. Stable uses bleeding edge (antipattern…)

Thus it seems like issues with the same root cause as in https://github.com/esprfid/esp-rfid/issues/354.

When I do a git checkout dev in the project folder to switch to the branch, and then Build / pio run

all is fine.

Switching back to stablebranch gives

… also a successfull compilation! :smiley:

This version is not found / correct in any of the two compilations.

I’d suggest you

  • rm -rf ~/.platformio/packages/framework-arduinoespressif8266* (to get rid of all versions of the Arduino-ESP8266 framework, they’ll be automatically reinstalled later)
  • pio upgrade --dev to get the latest PIO core version
  • try and build the stable branch again
  • try and build the dev branch

Thanks,
That sorted it on my PI and MAC, now to have a look at the project.

Thanks for quick response,

Steve
