Windows 7
sigh... cant you anwer properly? so you are running it on cygwin. you simply followed the guide step for step, thats why its easy for you. what part of my comment: "this script is for cygwin, and im not installing cygwin again" was unreadable for you?
so, for the record, i tried that script again on my lubuntu build setup, and as i said it needs some tweaking. it doesnt build the gcc itself for some reason. i have gcc 6.2.0 amiga toolchain and i have gcc4.6.4 and gcc 6.3.0 aros68k toolchains, but i doubt it will build with these out of the box if the default is 3.x.x.
perhaps i will build cahirs compiler by hand later, and retry the script. but now i need to work. probably it ll just get postponed and forgotten another time, as there is more pressing issues elsewhere.
