I've just installed the solaris2.8 binary package for ghc-6.0.1

I confess that I am running solaris2.9, which may be the cause of the problem, in which case I suppose I need to wait. But perhaps my problem is more general. I am trying to build HaLeX, a library for processing automata and regular expressions.

I have readline.h and history.h in /usr/local/include/readline, so the following error message is puzzling to me:

HaLeX:make ghc --make -I./src -i./src -package util -O2 ./src/Main.hs -o ./bin/halex Chasing modules from: ./src/Main.hs Compiling RegExp ( ./src/RegExp.hs, ./src/RegExp.o )

./src/RegExp.hs:20: Warning: `RegExp' is exported by `RegExp' and `RegExp(..)' In file included from /tmp/ghc18853.hc:6: /home/matt/lib/ghc-6.0.1/include/HsReadline.h:5: readline/readline.h: No such file or directory /home/matt/lib/ghc-6.0.1/include/HsReadline.h:6: readline/history.h: No such file or directory make: *** [halex] Error 1

I suspect that GHC isn't looking in /usr/local/include for include files. Adding -I/usr/local/include might help. A better fix is to modify the package configuration for the util package to add "/usr/local/include" to the list of include_dirs. Nobody's fault, really: the GHC package you installed was simply built on a system that had the readline headers installed in a different place. Cheers, Simon
