The Alpha distribution is meant to be built with GCC 2.5.x. It works with 2.6.0 too, except for one thing: 2.6.0 generates Makefile dependencies in a slightly different format. The difference is big enough to break the "make depend" rule in scout/sys/makefiles/Makefile.post. Below is a patch that should fix the problem. *** scout/sys/makefiles/Makefile.post 1994/06/11 00:03:14 --- 1.2 1994/08/10 16:49:37 *************** *** 36,42 **** files="`echo *.c` $(SRCS)"; \ if [ "$$files" != '*.c' ]; then \ gcc -M $(INCDIRS) $$files | \ ! sed -e 's@^\(.*.o\)\ :@$$(OBJDIR)/\1\ :@' \ >>Makefile.$(HOSTTYPE).new; \ else \ touch Makefile.$(HOSTTYPE).new; \ --- 15,21 ---- files="`echo *.c` $(SRCS)"; \ if [ "$$files" != '*.c' ]; then \ gcc -M $(INCDIRS) $$files | \ ! sed -e 's@^\(.*.o\):@$(OBJDIR)/\1:@' \ >>Makefile.$(HOSTTYPE).new; \ else \ touch Makefile.$(HOSTTYPE).new; \
