Odd. My Fedora Linux has the yacc(1) utility. Oh well. Please try the following: 1) Replace the rule for the "utparse.c" target in the file "lib/Makefile.in" with the following: utparse.c: utparse.y yacc -b utparse -d -p ut utparse.y cat utparse.tab.c > $@ rm utparse.tab.c cat utparse.tab.h > utparse.h rm utparse.tab.h 2) Execute the script "config.status" in the top-level source-directory (alternatively, you can re-execute the "configure" script). 3) Make a symbolic-link from someplace in your PATH to the bison(1) utility. 4) See if a "make" will now work.

There's a new version of the UDUNITS package known as UDUNITS-2. It uses XML and doesn't use yacc(1). Naturally, none of the packages you mentioned use UDUNITS-2. :-) > Many thanks for any help. > > Gus Correa Regards, Steve Emmerson Ticket Details =================== Ticket ID: OLI-727708 Department: Support UDUNITS Priority: Normal Status: Closed
