Begin active work (other than git clone and such ) at 18:09 on 05/28/2021

Quick look at bash history (to document git clones)

So this has been on again/off again for about two months. Glad to be wrapping it up.
|
||||
|
||||
Attempting to run the build script (./build-prerequisites.sh) gives us an error:
|
||||
|
||||
```console

|
||||
```
|
||||
|
||||
Which is expected as zlib isn't downloaded, though it arguably should be by install-sources.sh which utilizes build-common.sh which is where you find the
|
||||
actual download URLs. Light edit I did, was changing URLs from ftp to http. Between release.txt and the How-to-build-toolchain.pdf I got the following results:
|
||||
|
||||
```console
|
||||

|

||||
root@buildbox:/subo/Tooling/src/team-sweng/cross-compile/arduino-m0/gcc-arm-none-eabi-10-2020-q4-major#
|
||||
```
|
||||
|
||||
|
||||
Since this was written for ubuntu 14.04 , i'm guessing URLs are out of date.... so...
