Stuck on an issue?

Hi,

So after spending a bit of time fixing up my build script for m68k compilers I thought I’d take a look and see how it could be added to this repository. I have a few initial questions:

1. From what I’ve seen from the other cross compiler build scripts (like for example gcc-cross\build\msp430-gcc453) only the compiler is being built without libraries. My script also builds quite a few libs - are those not needed? I’m asking this because if only the barebones compilers are required then the build script gets significantly smaller.
2. I also asked this in the compiler-explorer issue - from what I understand the compilers are being installed in /opt - what would an accepted naming scheme be? @RabsRincon suggested gcc-x-x-x-68k, by default the compilers are named m68k-x-x-x-elf fwiw.
3. Can anyone help me figuring out how docker works? For my build I require a few versions of gcc to be present (4 through 7), the usual GMP/MPFR/MPC and a couple of others like flex and bison (if the libraries are being built). From what I understand there’s a repository of docker packages one can get and use the built-in tools but this is just dark arts for me right now 😃

Feedback welcome! George
