Hello, I've installed gcc-arm-none-eabi-49 via homebrew.
But when I tried creating the .out file for BBB_led_control.c using command : $ arm-none-eabi-gcc -o BBB_led_control2.out BBB_led_control.c, I got the following error:

This code is written for Beaglebone Black.
I hope someone has a solution to this.
Thank you

brew cask install caskroom/cask/gcc-arm-embedded does not work anymore for me. It says:

It has been removed: Delete gcc-arm-embedded.rb #56802. Alternatieve:

Hello @Markrus. I am wanting to make a custom version of the inav firmware based on the latest MATEKF405SERVOS6 build. This link is where I found out that what I want done to the firmware (set up motor pads for servo signal) can actually be done: iNavFlight/inav#3140
I am on a Mac and have begun following the steps listed in this link: https://github.com/iNavFlight/inav/blob/master/docs/development/Building%20in%20Mac%20OS%20X.md
I am at the place where I should install the GCC. This is where I don't understand how to proceed. I have not done any coding in forever and I'm unsure how to enter the commands correctly. I have created a folder in my User folder called "Development". The latest GCC tarball is there and I unpacked it into the same folder by double clicking it. I now have a folder entitled "gcc-arm-none-eabi-8-2018-q4-major" inside the "Development" folder along with the original tarball. My User folder is called "gerelmcintosh". The path to the GCC tarball and GCC folder is gerelmcintosh/Development. How would l word the command in the Nano program running in my Terminal to get the GCC "installed"?
Thanks @markruys, I ran brew install px4/px4/gcc-arm-none-eabi which worked just fine for me.
There are a number of solutions in this thread, but the official download from brew and ARM with :
brew cask install gcc-arm-embedded
is by far the simplest and easiest.
The correct command to install gcc-arm-embedded is: brew install homebrew/cask/gcc-arm-embedded
The install works great. However when it is done the compile is unusable due to MacOS security. Is there a way to bypass the new security in Catalina?
@curtisembedded open Security & Privacy, in the general tab allow gcc-arm-none-eabi to run
brew cask install gcc-arm-embedded
This works even in 2020. Nice one.
brew cask install gcc-arm-embedded
Works Fine in MacBook Pro 2020
brew install --cask gcc-arm-embedded
Had to use this one since I got the error Calling brew cask install is disabled!
Is this 32-bit only?
+1 to brew cask install gcc-arm-embedded. Thank you!
Works as expected on Mac M1 (cask installed from a Rosetta brew - i.e. arch was i386 to ensure placing in /usr/local/bin and not in /opt/homebrew/bin).
brew cask no more works after 2022.
Instead, use brew install gcc-arm-embedded --cask to install.
Thanks @jeremyheiler anyway.
thank you
@impressivemachines good job，thank you
