Compiling Error redefinition of 'float fabsf'

[sniperlucian]

trying to compile with Arduino IDE 1.8.19 on Linux (Manjaro).

Get following compile error:

OpenAstroTech/OpenAstroTracker-Firmware/src/Utility.cpp:212:7: error: redefinition of 'float fabsf(float)'

Hmm, can't replicate on my end. Arduino IDE 1.8.19 on Manjaro as well: https://gist.github.com/julianneswinoga/b2ca9b2b51629eee0e0d570969521e47

Could you try platformio? It's really easy on linux:

$ cd OpenAstroTracker-Firmware
$ python3 -m venv .venv # create virtual environment
$ ./.venv/bin/pip install platformio # install pio to virtual environment
$ ./.venv/bin/pio run -e ramps # build firmware

Closing because no response

sorry - completely missed the replay.

compilation run through with platformio.

[julianneswinoga]

Sorry, you're saying that it worked with platformio?

[sniperlucian]

yes it worked with platformio.

• made a fresh git clone
• generated basic config file with web interface (doesn't work with default config - missing parameter)
• followed your steps
• compilation run successful trough

guess I need to take a deeper look at platformio - its new to me ;)
