I dont know about c
Im a noob programmer
Just i'm asking

I want to compile for x86_64 architecture for no reason( just want to run with my pc mcpi ...) and first: cmake
Of course it had to give errors so I modified CMakeLists.txt to NoT run arm toolchain in cmake/building

CMake Deprecation Warning at build/_deps/libpng-src/CMakeLists.txt:1 (cmake_minimum_required):
  The OLD behavior for policy CMP0054 will be removed from a future version
  of CMake.

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.

I have renamed $PWD to . to... protect? idk like protecting some useless

next: make

Seems like it is solved, true?

NO

make -j16 (yes, let me change pc by small beast)

YES, I dont understand, just a bit BIT
And I want to ask to people who knows C to answer to my question:

Can minecraft-pi-reborn/libreborn/src/reborn.c be modified to NOT return errors?
I mean to make it compile to allllllll architectures, not only x86_64

Tnks :D

Probably best to not compile it yourself, precompiled debs already exist for amd64, armhf, and arm64
