Build on mac

• Download crosstool-ng, brew install crosstool-ng
• crosstool-ng requires a case-sensitive file system, so you'll have to create one (Thanks for the instructions, whomever wrote the ones ChatGPT stole)

  1. Open Disk Utility: You can find Disk Utility in the "Utilities" folder within the "Applications" folder, or you can search for it using Spotlight.

  2. Create a new disk image: Click on "File" in the menu bar and select "New Image" -> "Blank Image."

  3. Configure the disk image settings:

     • Choose the desired size and name for the disk image. I chose 10 GB
     • Select "Mac OS Extended (Case-sensitive, Journaled)" as the format.
     • Choose the location where you want to save the disk image.

  4. Create the disk image: Click on the "Save" button to create the disk image with the specified settings.

  5. Mount the disk image: Double-click on the disk image file to mount it. It should appear as a new volume on your desktop.

  6. Give the file system a name in finder. Note the full path to this directory, typically it will be in /Volumes. I named mine RPI-Toolchain

• Setup the toolchain in this new file system
  1. cd /Volumes/RPI-Toolchain
  2. mkdir toolchain tarballs
  3. ct-ng menuconfig
  4. In the configuration menu, make the following selections:
     • Select "Target options" and set the "Target Architecture" to "arm".
     • Select "Operating System" and set the "Target OS" to "linux".
     • Select "Paths and misc options" and set the "Prefix directory" to the directory you created earlier (e.g., /Volumes/RPI-Toolchain/toolchain).
     • Select "Paths and misc options" and set the "Local tarballs directory" to /Volumes/RPI-Toolchain/tarballs
     • Select "C Compiler" and key down to enable C++ and Fortran by pressing space bar on their options.
     • Determine the glibc version on your pi ldd --version. Then, select "C-library" and find the option for glibc version and set it appropriately
     • Save the configuration and exit the menu.
• Open up .config and change CT_ZLIB_VERSION to "1.2.13"
• Open up .config and comment out CT_GLIBC_ENABLE_WERROR=y
• Build the toolchain, ct-ng build
• If you run into errors, this repo may have a solution
