@cozycactus that error message makes me think something is not right in your Ubuntu installation of the 'FX3 SDK for Linux platforms' (item 4 in the 'EZ-USB FX3 Software Development Kit': https://www.cypress.com/documentation/software-and-drivers/ez-usb-fx3-software-development-kit).

Can you run these 'find' commands to figure out where those two static libraries are located on your system?

find /usr -name libc.a | grep arm
find /usr -name libgcc.a | grep arm
find /opt -name libc.a | grep arm
find /opt -name libgcc.a | grep arm

If those commands return no results, I would reinstall the EZ-USB FX3 SDK for Linux following the instructions from the README (https://github.com/ik1xpv/ExtIO_sddc#build-instructions-for-firmware).

Hope this helps, Franco

@cozycactus - given the output of your 'find' commands, I think that in the SDDC_FX3 firmware build (https://github.com/ik1xpv/ExtIO_sddc#build-instructions-for-firmware), you have to set those three environment variables to something like this:

export FX3FWROOT=<installation path>
export ARMGCC_INSTALL_PATH=/usr/share/gcc-arm-none-eabi-10.3-2021.07
export ARMGCC_VERSION=10.3.1

(they might need to be slightly tweaked; if the build still fails with these new values for the environment variables, you should be able to see what they should be set to in your Ubuntu computer).

Thank you! it compiles now
