work log

2022-06-12: vm4 - to build cpm68, you need to have the rosco_m68k repo at the same level, like this

tingo@kg-vm4:~/work/68k-projects/rosco-m68k$ l
./  ../  cpm68k/  rosco_m68k/

and you need to do a build in software first, like so

cd rosco_m68k/
cd code/
cd software/

then go to cpm68k and do a 'make' there, it should be like this

tingo@kg-vm4:~/work/68k-projects/rosco-m68k/cpm68k$ make

2022-06-11: vm4 - installing toolchain on a Debian machine. First, install curl, cpmtools and srecord via apt. curl is used to install Homebrew, cpmtools and srecord is used as tools in the build process. Next, install homebrew

tingo@kg-vm4:~$ /bin/bash -c "$(curl -fsSL"

and follow the instructions to add it to ~/.profile, PATH etc.

eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)"

is useful. Next, install the toolchain

tingo@kg-vm4:~$ brew install binutils-cross-m68k
tingo@kg-vm4:~$ brew install vasm-m68k
tingo@kg-vm4:~$ brew install gcc-cross-m68k@11

that's it.
