Workaround for Ubuntu 18.04/18.10 problem with ARM toolchain to compile Calliope-Programs

[Ralph Maas]

We use openroberta on several (old) laptops with lubuntu.

After the upgrade to 18.10 (cosmic) we could no longer compile programs for Calliope.

The server log reported a missing "cstddef" library.

After long research we found the following post:

https://unix.stackexchange.com/questions/453032/how-to-install-a-functional-arm-cross-gcc-toolchain-on-ubuntu-18-04

With this information the following workaround helped for us:

----

sudo apt remove binutils-arm-none-eabi gcc-arm-none-eabi libnewlib-arm-none-eabi

download

https://developer.arm.com/-/media/Files/downloads/gnu-rm/8-2018q4/gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2?revision=d830f9dd-cd4f-406d-8672-cca9210dd220?product=GNU%20Arm%20Embedded%20Toolchain,64-bit,,Linux,8-2018-q4-major

cp /home/roberta/Downloads/gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2 /home/roberta

cd /home/roberta

tar -xjvf gcc-arm-none-eabi-8-2018-q4-major-linux.tar.bz2

We then start the server with this script:

---

#!/bin/bash
export PATH=$PATH:/home/roberta/gcc-arm-none-eabi-8-2018-q4-major/bin
cd /home/roberta/robertalab
./ora.sh --start-from-git

---

Hope this post helps others with the same problem.

Best regards

Wow, thank you very much!

I remember that we have had a couple of similar problems. Most of them disappeared after a some weeks for 18.04. But still on ubuntus, updated from 16.04 to 18.04 they still exist. Also it may help for the machines that have problems with running calliope and arduino compilers.  I will try your workaround asap.
