Hi, I've went through the process of compiling Luma 3DS on my mac and thought I'd do a write up of the different steps involved. This guide presupposes that you know your way around the command line Hope it's useful. 1. Install gcc from Homebrew and set the env variables + aliases: export CC=/usr/local/bin/gcc-5 export CXX=/usr/local/bin/g++-5 export CPP=/usr/local/bin/cpp-5 export LD=/usr/local/bin/gcc-5 alias c++=/usr/local/bin/c++-5 alias g++=/usr/local/bin/g++-5 alias gcc=/usr/local/bin/gcc-5 alias cpp=/usr/local/bin/cpp-5 alias ld=/usr/local/bin/gcc-5 alias cc=/usr/local/bin/gcc-5 2. Download the perl script for devkitPro at http://sourceforge.net/projects/devkitpro/files/Automated Installer/devkitARMupdate.pl/download cd /path/to/the/script chmod +x devkitARMupdate.pl sudo ./devkitARMupdate.pl /opt/devkitPro echo "export DEVKITPRO=/opt/devkitPro" >> ~/.bashrc echo "export DEVKITARM=\$DEVKITPRO/devkitARM" >> ~/.bashrc echo "export PATH=\$PATH:\$DEVKITARM/bin" >> ~/.bashrc source ~/.bashrc 4. Replace libctru with Smealum's version You can get his libctru at http://github.com/smealum/ctrulib.git Compile with make and then replace libctru from /opt/devkitPro with smealum's version 5. Install gcc-arm-embedded with brew install Caskroom/cask/gcc-arm-embedded 6. Armips and bincc Armips: First install cmake if you don't have it. Then: git clone --recursive http://github.com/Kingcom/armips.git cd armips mkdir build; cd build; cmake ..; make (Remember to build with gcc from homebrew not clang) bin2c: Get bin2c from here http://sourceforge.net/projects/bin2c/files/1.1/bin2c-1.1.zip/download gcc bin2.c -o bin2c 7. Get Luma 3ds repository (clone --recursive) and run make I've also made a gist with this content here http://gist.github.com/zentis/b3c55f67f79e2931a2ec0e257b15ef90 I'll upload the armips and bin2c binary later tomorrow if there's interest so that you can bypass step 6.
