I'm trying to install arm-elf-eabi-gcc so I can build Rockbox, but I haven't found out how to install it. Does anybody have a working method for installing it?

What is your operating system?

[__builtin]

What platform are you building on? nproc is a coreutils component.

macOS Catalina. I'm trying to install rockbox on an iPod 5th Gen.

The last few versions of MacOS have broken compatibility with a lot of our development tools. When I tried a few years back, the first thing thing I had to do was install gcc (since Apple stopped supporting it in favor of llvm).

Alternatively you could use a Linux VM or find a windows machine.

Apply this (I'm going to add it to git later, after I checked it on Linux):

Code: [Select]

diff --git a/tools/rockboxdev.sh b/tools/rockboxdev.sh
index 6b12fa015e..09b420c0c9 100755

After that you'll need further tools, likely best approach is to use homebrew.
