Hi, I have tried to have GHC in my Raspberry Pi, got stuck in the issue 7754 (https://ghc.haskell.org/trac/ghc/ticket/7754), since I didn't know where to pass options to terminfo's configure file, although I did copy the headers from my Raspberry Pi. I've been using HUGS ever since, as Arch Linux doesn't have GHC for ARMv6, and deb2targz would not work. I'm aware I have a phase 0 compiler installed, need to build a phase 1 compiler, and use that to cross-compile GHC itself (I wasn't the 1st time I tried, couldn't find as much information as now). I've read the following pages: https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/RaspberryPi https://ghc.haskell.org/trac/ghc/wiki/Building/CrossCompiling https://ghc.haskell.org/trac/ghc/wiki/CrossCompilation along with quite a few bug reports, and questions on Stack Overflow that seemed related but really aren't, or that are already exposed in the tickets mentioned below. Below, /home/jmcf125/ghc-raspberry-pi/ghc/libraries/terminfo/include-curses and /home/jmcf125/ghc-raspberry-pi/ghc/libraries/terminfo/lib-curses are directories to which I copied any headers and libraries, respectively, from my Raspberry Pi. I'm not sure which libraries I am supposed to point configure at. These are the headers-libraries combinations I tried: $ ./configure --target=arm-linux-gnueabihf --with-curses-includes=/home/jmcf125/ghc-raspberry-pi/ghc/libraries/terminfo/include-curses --with-curses-libraries=/home/jmcf125/ghc-raspberry-pi/ghc/libraries/terminfo/lib-curses && make -j5 (...) checking for unistd.h... yes checking ncurses.h usability... no checking ncurses.h presence... no checking for ncurses.h... no checking curses.h usability... no checking curses.h presence... no checking for curses.h... no configure: error: in `/home/jmcf125/ghc-raspberry-pi/ghc/libraries/terminfo': configure: error: curses headers could not be found, so this package cannot be built See `config.log' for more details libraries/terminfo/ghc.mk:4: recipe for target 'libraries/terminfo/dist-install/package-data.mk' failed make[1]: *** [libraries/terminfo/dist-install/package-data.mk] Error 1 Makefile:71: recipe for target 'all' failed make: *** [all] Error 2 (https://ghc.haskell.org/trac/ghc/ticket/7754) $ ./configure --target=arm-linux-gnueabihf --with-curses-includes=/usr/include --with-curses-libraries=/home/jmcf125/ghc-raspberry-pi/ghc/libraries/terminfo/lib-curses && make -j5 (...) checking for unistd.h... yes checking ncurses.h usability... yes checking ncurses.h presence... yes checking for ncurses.h... yes checking for setupterm in -ltinfo... no checking for setupterm in -lncursesw... no checking for setupterm in -lncurses... no checking for setupterm in -lcurses... no configure: error: in `/home/jmcf125/ghc-raspberry-pi/ghc/libraries/terminfo': configure: error: curses library not found, so this package cannot be built See `config.log' for more details libraries/terminfo/ghc.mk:4: recipe for target 'libraries/terminfo/dist-install/package-data.mk' failed make[1]: *** [libraries/terminfo/dist-install/package-data.mk] Error 1 Makefile:71: recipe for target 'all' failed make: *** [all] Error 2 (https://ghc.haskell.org/trac/ghc/ticket/7281) $ ./configure --target=arm-linux-gnueabihf --with-curses-includes=/usr/include --with-curses-libraries=/usr/lib && make -j5 <OR> $ ./configure --target=arm-linux-gnueabihf --with-curses-includes=/home/jmcf125/ghc-raspberry-pi/ghc/libraries/terminfo/include-curses --with-curses-libraries=/usr/lib && make -j5 (...)

I tried them anyway, since the 1st 2 errors didn't seem to make sense... Also, options --includedir and --oldincludedir seem to have no effect (always get issue 7754), and it doesn't matter if I build registarised or not, the results are the same (registarised, I'm using LLVM 3.6.2-3). I'm sorry if I'm wasting your time with what to you might seem such a simple thing, and not real development on GHC, but I don't know where else to turn to. I'm still learning Haskell, and have never had to compile compilers before. Thank you in advance, João Miguel
