Everything seems to compile, but at the link stage the following results: ---- gcc -o pl -Lrc pl-atom.o pl-wam.o pl-stream.o pl-error.o pl-arith.o pl-bag.o pl -comp.o pl-rc.o pl-dwim.o pl-ext.o pl-file.o pl-flag.o pl-fmt.o pl-funct.o pl-gc .o pl-glob.o pl-itf.o pl-list.o pl-load.o pl-modul.o pl-op.o pl-os.o pl-prims.o pl-pro.o pl-proc.o pl-prof.o pl-read.o pl-rec.o pl-rl.o pl-setup.o pl-sys.o pl-t able.o pl-trace.o pl-util.o pl-wic.o pl-write.o pl-term.o pl-buffer.o pl-thread. o pl-xterm.o pl-feature.o pl-ctype.o pl-main.o pl-extend.o frame.o -lrc -lreadli ne -lncurses -lm pl-rl.o(.text+0x1c1):pl-rl.c: undefined reference to `rl_event_hook' pl-rl.o(.text+0x1ce):pl-rl.c: undefined reference to `rl_event_hook' collect2: ld returned 1 exit status make: *** [pl] Error 1 ---- I checked, and libreadline.a is in /usr/lib, and of course a run of nm -s libreadline.a shows entries for _rl_event_hook. I just updated my cygwin installation this week (Monday?). Any idea why the linker can't find it? Or what to check? (By the way, librc.a is a library prepared as part of the compile, and it was apparently build successfully). Sorry if this isn't an appropriate Cygwin question.
