New to A20 and Python

[brianr]

Hi Folks,

Hopefully these questions will have a quick resolution. I have an A20 board running the Debian image spoiled by Olimex. So Python seems to work OK, been able to install idle and pip. However installation of the pyA20 package fails, it can't compile the libraries. I can't post the exact message but it looks to be that the compiler command is wrong.

So, how do you install the latest pyA20 package?

What is the magic to get the C/C++ compiler going? Gcc is unknown, the compilers appear to be there.

Cheers

Brian

For the record the pyA20 install via pip gives:

looks like you are trying to cross compile it, if you are compiling on the board you just need gcc not arm-linux-gnueabihf-gcc, if gcc is not on the system try

Code Select Expand

sudo apt-get install build-essential

Yep that helped somewhat!
