I hope this is not off-topic, because there is no better place to ask this sort of questions on SO/SE. I have Downloaded and ran PureDarwin on QEMU using instructions here:
Now I want to know if there are any package managers? Can I install HomeBrew preferably here for example or even MacPorts? If none possible how can I install GNU C/C++/Fortran compilers (GCC/g++/gfortran) here? or if it is not a possibility is there any compiler on this operating system at all? My goal is eventually to provide some Open Source developers who don't have macs with an alternative to test their software or maybe create macOS compatible binaries/packages if possible. Thanks for your support in advance.
