/usr/libexec/gcc/arm-none-eabi/ld: cannot find -lc_nano #3

Closed mapmot closed 6 years ago

This needs cross-arm-none-eabi/newlib-nano. An attempt can be found in sys-libs/newlib[nano]. This was taken from https://forums.gentoo.org/viewtopic-t-1017098-start-0.html, but I am unable to get it to work.

Did you try "--specs=nano.specs"?

Here's what I have installed on the udoo board, it compiled and flashed demo sketches just fine using 5.4.0 and a slightly modified version of the USE="nano" ebuild on the forum post:

It works now using the ebuild in the overlay. I honestly don't remember what the problem was.
