Docker image and repo for Arm64 (new Mac) build of Minix 3.4.0-i386

[Lincoln Ombelets]

Hi,

I have recently discovered Minix and am interested in learning OS development on it. I am working on an aarch64 (arm64) MacBook and was having trouble compiling it, so I've made a Docker image where I was able to compile Minix 3.4.0 for i386. I also wrote a README explaining how I compile on this image and how to get the resultant image running on the QEMU emulator. It's all here: https://github.com/lincdog/minix

I incorporated recent fixes from https://github.com/Stichting-MINIX-Research-Foundation/minix/pull/322 and updated a few config.guess that didn't work properly with Arm64 compilation environments. 

The docker image is here:

https://hub.docker.com/r/lincdog/minix-build-arm64

There is one version that contains the actual built objects (saves time from compiling the LLVM/clang toolchain) and another that just has the source and nothing built. The source is at /usr/src.

I hope this will help anyone who wants to play around with Minix on an arm64 computer like a new Mac. This Docker image could be built on an x86 Ubuntu base as well.

Thanks,

Lincoln Ombelets

Hello Lincoln,

Thank you very much for your effort!

What problems did you have while building Minix on Mac?

Best regards,

Peter

Hi Peter,

Thanks! It seems to encounter an implicit function declaration error pretty early on in the toolchain build:

/minix/tools/compat/../../common/lib/libc/cdb/cdbr.c:286:2: error: implicit declaration of function 'mi_vector_hash' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
mi_vector_hash(key, key_len, cdbr->seed, hashes);
^
