Build on Raspbian PIXEL #3

Closed ghost closed 7 years ago

ghost commented 7 years ago

On a brand new Raspbian PIXEL install on RPI3, i get the following while trying to build from github?

pi@dev:~/LiFePO4wered-Pi $ ./build.py

gcc -c lifepo4wered-access.c -o build/DAEMON/lifepo4wered-access.o -std=c99 -Wall -O2

Obviously, i haven't yet tried the install script.

Resolved, re-installed everything from scratch.

For those that run into the same issue, it was caused for me by having libi2c-dev installed. So, you can temporarily uninstall libi2c-dev, compile the LiFePO4wered-Pi tools, and then reinstall libi2c-dev, like so (from within the cloned repo):

sudo apt-get remove -y libi2c-dev
./build.py
sudo ./INSTALL.sh
sudo apt-get install -y libi2c-dev

This appears to be an upstream problem that's should be already fixed but may not have made it to Raspbian yet.

Thanks for reporting a solution for this, since I had not been able to duplicate it myself!
