Please note that if you ask for help in places not listed here you may end up getting very poor advice which may cause problems with the tools. Generally we advise against installing 3rd party tools and libraries and we especially advise against modifying your devkitPro provided installation without advice from devkitPro staff. People in other places have an unfortunate habit of seeking to fix the symptoms of a problem without first determining why the problem has occurred. devkitPro staff also like to understand why someone is seeking to do something before helping them do whatever it is they want to do rather than just blindly answering questions at face value. The XY problem tends to get exacerbated by other users "solving" the stated problem when the toolchain maintainers can quite often solve the actual problem since we're familiar with the symptoms of many obscure issues thanks to our long experience,
