(Moving to the cafe) On a related topic, I've been trying to build 6.8.2 on Leopard lately. I've been running up against the infamous OS X readline issues. I know some builders here have hacked past it, but I'm looking for a good workaround... ideally one that works without changes outside the GHC build area (besides installing a real readline). Here's what I noticed before I started drowning in the build platform. (I'm no gnu-configure expert nor GHC insider.) I can get gnu-readline installed from Macports, no problem. The top-level configure in GHC doesn't respond to my various attempts: o using --with-readline-libraries and --with-readline-includes (Although it looks like the libraries/readline/configure script might recognize these, I can't get an option to pass through.) o setting LDFLAGS and CPPFLAGS environment variables (with -L/opt/local/lib and -I/opt/local/include resp.) in my shell before running configure o playing with the above settings and others in a mk/build.mk Until Apple fixes their broken-readline issue (maybe when the readline compatibility of libedit improves)... maybe the top-level configure can pass through flags or settings somehow? For those who've built with readline on OS X: have you had to resort to blasting the existing readline library link, or is there a configuration option within the GHC tree that you've gotten to work? Should I be filing a trac bug instead of asking here? Thanks for any help. There's no urgency for me; I'm just trying to get a working environment at home; I'd prefer to be able to bootstrap from the ground up; and I'd like to be able to contribute to testing/debugging on OSX.
