GNU Arm Embedded Toolchain

I would like to have both toolchains (gcc-arm-embedded and arm-non-aebi) parallely installed in my ubunut environment. First one is needed for the Paparazzi and second one for the PX4 software. What should I do?

Asked by Gabriel König on 2018-02-22

The following error messages occurs, trying to install the Paparazzi dependencies.

Preparing to unpack .../gcc-arm-embedded_7-2017q4-1~xenial2_amd64.deb ...
Unpacking gcc-arm-embedded (7-2017q4-1~xenial2) ...

E: Sub-process /usr/bin/dpkg returned an error code (1)

Can I keep the arm-non-eabi or do I need to remove it?

Thanks for your help?

Hi Gabriel,

TL;DR: you should only need one of those toolchain

The gcc-arm-embedded package in our PPA targets arm-none-eabi as well. I'm guessing the one you already have installed is the standard Ubuntu one which is based on the same source tarballs as the one we provide in our PPA. The one in our PPA might be one version ahead since new releases are uploaded in the PPA at the same time as we release a new version of the GNU Arm Embedded toolchain. If you wish to use the PPA toolchain (eg. if you need something more recent) you will have to remove the gcc-arm-none-eabi, binutils-arm-none-eabi, gdb-arm-none-eabi and libnewlib-arm-none-eabi packages first.

Hi Thomas

Thank you for the fast response.

The thing is that I need for the PX4 (resp. for the NuttX-based Hardware) a specified arm-non-eabi version.
See description (https://dev.px4.io/en/setup/dev_env_linux_ubuntu.html#nuttx-based-hardware).
I know that I removed already once in the past the arm embedded ppa, as the manual also demands:
sudo add-apt-repository --remove ppa:team-gcc-arm-embedded/ppa

Thus my question would be, can I install the arm-embedded-toolchain, wich has the source tarballs for the desired gcc-arm-none-eabi-7-2017-q4 version. Thus is it possible to change the arm-none-eabi version after installing the gcc-arm-embedded package?

Cheers
Gabriel

Hi Gabriel,

I've followed your link with interest and from what I can see after a quick look the toolchain the script downloads seems to be exactly the same as the latest version in our PPA. Therefore I'm not sure why the instruction requires removing the PPA as being a too old version.

That said, assuming this is a custom toolchain with extra things in it (and if it is I'd recommend them to get in touch with us) you can install our tarball anywhere in your computer and play with PATH to select the toolchain you actually want to use. That is, you could install one toolchain in /usr/local/nuttx and another one in /usr/local/gnu-arm-embedded-official and put the right folder in your PATH to select the toolchain you want to use.

Best regards.
