Unfortunately having gone back to v5.04.3 I'm back to the readline errors. I've been trying the build option to link against the fink copy again but it still doesn't compile... I can't see a similar place in the config file to add the relevant commands:

Unfortunately, there is no attempt to detect readline in the Hat configuration scripts. It simply assumes that if you use ghc, readline is available without extra arguments.

Maybe the best thing to do is just to disable readline for now. In Hat, it is only used for editing commands in the browser hat-observe, but can easily be omitted. In the file src/hattools/Makefile, change the line

HMAKEFLAGS = -fglasgow-exts -package lang -package util -DUSE_READLINE=1 to HMAKEFLAGS = -fglasgow-exts -package lang -package util -DUSE_READLINE=0

Hmm, that doesn't seem to have stopped make looking for readline: [nimbus2:~/Desktop/project/hat-2.02] tatd100% make cd src/hattools; make HC=ghc install hmake -hc=ghc -fglasgow-exts -package lang -package util -DUSE_READLINE=0 SrcRefViewer \ -d/Users/tatd100/Desktop/project/hat-2.02/targets/powerpc-Darwin6/obj/ hattools cd /Users/tatd100/Desktop/project/hat-2.02/targets/powerpc-Darwin6/obj/ hattools && ghc -fglasgow-exts -package lang -package util -o SrcRefViewer HighlightStyle.o Run.o SrcRefViewer.o ld: can't locate file for: -lreadline make[1]: *** [/Users/tatd100/Desktop/project/hat-2.02/lib/powerpc-Darwin6/hat-view] Error 1 make: *** [targets/powerpc-Darwin6/hat-tools-ghc] Error 2 Thanks Tom Davie
