You should be able to follow the instructions in the project README file to automatically set up and install the build chain (in a prefix within the repository). If you encounter problems, please proceed with Install the build chain (manual steps).

Once you have the build chain set up, just follow Building GNU-EFI and Install remaining dependencies.

Install the build chain (manual steps)

Compile x86_64-elf-binutils with the tools we require, then compile the cross-compiler (x86_64-elf-gcc) without a hosted standard library.

  1. Install x86_64-elf-binutils in interactive mode. We need to add --enable-targets=all to get EFI app support: 
    brew install --build-from-source x86_64-elf-binutils -i
# after you ran brew install, it should have displayed a message indicating
# which prefix to install to.
./configure --enable-targets=all --target="x86_64-elf" --disable-nls --prefix="<< the prefix from brew install >>"
make
make install
exit
  2. Next, run a similar procedure for the GCC ELF cross-compile toolchain: 
    brew install x86_64-elf-gcc --build-from-source -i
# gcc misbehaves if you don't install from a sub-directory
mkdir x86_64-elf-gcc-build; cd x86_64-elf-gcc-build
# after you ran brew install, it should have displayed a message indicating
# which prefix to install to.
../configure --target=x86_64-elf --prefix="<< the prefix from brew install >>" --disable-nls --without-isl --without-headers --enable-languages=c,c++ --with-as="$(which x86_64-elf-as)" --with-ld="$(which x86_64-elf-ld)" --disable-hosted-libstdcxx
# now make gcc and libgcc
make all-gcc
make install-gcc
make all-target-libgcc
make install-target-libgcc
exit

Building gnu-efi

Build the patched copy of gnu-efi 3.0.14 in third-party/gnu-efi.

  1. If you don't already have Homebrew installed, I'd highly recommend installing it: 
    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
  2. Grab a supplementary ELF header (elf.h) file with: 
    curl https://gist.githubusercontent.com/SamJakob/8b0de39e1d1fcde5c7df204d7e2d899b/raw/elf.h | sudo tee /usr/local/include/elf.h

    I've modified this file based on suggestions in a reply such that it compiles on macOS 11.

  3. Build gnu-efi with: 
    export CROSS_COMPILE="x86_64-elf-"
export CFLAGS='-I /usr/local/include'
make
sudo ARCH=x86_64 make install

Install remaining dependencies

Then, install the remaining build-system dependencies

brew install dosfstools
brew install mtools
