3DS Linux build instructions

Step 1: Compiling or Downloading the toolchain

Step 1.a: If you choose to download a pre-compiled toolchain (only for Linux x86-64)

  • Go to https://toolchains.bootlin.com
  • Select arch: armv6-eabihf
  • Select libc: glibc
  • Download bleeding-edge
  • Uncompress it (for example to /opt)
  • Add the bin/directory of the toolchain to $PATH
  • In my case: export PATH=$PATH:/opt/armv6-eabihf--glibc--bleeding-edge-2020.08-1
