Oy. I've read everything. So, can anyone help... machine% /usr/ccs/bin/make yacc -d parser.y sh: yacc: not found *** Error code 1 make: Fatal error: Command failed for target `parser.o' This worked fine for me on SunOS, but this is my first Sparc/Solaris, er, experience. Thanks for any clue or part thereof. G.
