GNU ARM - nano.specs not found

Question

Last days I've been trying to compile a STM32F4xx project with Ubuntu 14.04LTS, Eclipse and GNU ARM plugin for Eclipse. Now it says that nano.specs is missing. Here is my build log:

I found some nano.specs files on my computer. What should I do? Just remove linker flag (I can't actually do that, because I can't figure out how to do that in Eclipse) or something else? Thanks for your help!

Answer 1

I solved the problem. I was just using arm-none-eabi-xxx packages provided by Ubuntu, not original ones - that was the problem. All you need to do is simply download packages from toolchain's website and install them. They work just fine!

Great. Any advice about how to install this toolchain? Do I need to uninstall some packages and then unpack it somewhere? I am also using Eclipse as my IDE. – Massotherapy

Optional step

If you have installed the bundled toolchain from Ubuntu's repositories - get rid of them:

$ sudo apt-get remove gcc-arm-none-eabi

Recommended way to install

This is described on the plugin's page:

http://gnuarmeclipse.github.io/toolchain/install/

-> with an exact description what packages are needed for your specific edition (14.04 LTS, x64 in this case).

First, install 32-bit dependency libraries:

$ sudo apt-get -y install lib32z1 lib32ncurses5 lib32bz2-1.0

(15.04 - and later? - need just lib32ncurses5, while older Ubuntus - 12.04 e.a. - have ia32-libs).

Then download a pre-compiled toolchain package from here:

https://launchpad.net/gcc-arm-embedded/+download

(they recommend gcc 4.9 at the time of writing, but it should be OK to take the newest, gcc 5.3 version).

Recommended install location

Finally untar the package into /usr/local - this way the Eclipse plugin should find it, without configuring toolchains in Eclipse preferences or modifying $PATH variable.

$ cd /usr/local
$ sudo tar xf ~/Downloads/gcc-arm-none-eabi-*-linux.tar.bz2

Very nice answer! This is exactly what I did after facing the problem. I can see you found out how to install everything but if anyone is interested, this is video that helped me a lot, when I was setting everything up – Pretender

Answer 3

If you are compiling for ARM Cortex-M or Cortex-R, try installing the package gcc-arm-embedded with apt-get instead of gcc-arm-none-eabi. This worked for me, and the suggestion came from the documentation for Arm's "Yotta" build tool: http://yottadocs.mbed.com/#linux-cross-compile.
