I downloaded the GHC 6.6 tarballs, built and installed them on my mac (Tiger, PPC) using the documented procedure: ./configure make make install
The build and install was fairly smooth. However, ghci will not recognize "control characters", e.g. delete/backspace, arrow keys, ctrl-a, ctrl-d et c. It seems to recognize ctrl-c for cancellin5.2g a line but will print the ^C first. A typical session may look like:
It sound like either you don't have readline installed, or the GHC build didn't detect it. Do you have readline? (the real GNU readline, not Apple's version).
I have GNU readline 5.1 installed through darwinports. As for the GHC build detecting it I wouldn't know. Rerunning ./configure produces the following lines mentioning readline (note that I have already built and installed GHC 6.6 and have it in the path): checking whether ghc has readline package... no checking readline/readline.h usability... yes checking readline/readline.h presence... yes checking for readline/readline.h... yes checking readline/history.h usability... yes checking readline/history.h presence... yes checking for readline/history.h... yes configure: configuring in readline checking for readline in -lreadline... yes checking for rl_readline_version in -lreadline... no config.status: creating readline.buildinfo config.status: creating include/HsReadlineConfig.h config.status: include/HsReadlineConfig.h is unchanged I don't know what to make of the above.
