Hello again, OK, scratch that again. It barfs in the same place running from "sh". I thought it had got further but then i manually generated cpudefs.c! After a "make clean", typing make in sh barfs at teh same point. If I manually CD into src/tools and type "build68k <../table68k >cpudefs.c" it works and then the make can continue after that point. ... and then it bombs compiling support.c. Attached is the console output. Cheers, Pete
