Hi, I'm trying to build ghc for raspberry pi, but I'm having problem with .configure. I'm following these instructions from ( https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/RaspberryPi). I have the tools installed and they should be also in my PATH,..... Please any ideas? ghc> ./configure --target=arm-linux-gnueabihf --enable-unregisterised checking for gfind... no checking for find... /usr/bin/find checking for sort... /usr/bin/sort checking for GHC version date... inferred 7.9.20141121 checking for ghc... /usr/bin/ghc checking version of ghc... 7.6.3 checking build system type... x86_64-unknown-linux-gnu checking host system type... x86_64-unknown-linux-gnu checking target system type... arm-unknown-linux-gnueabihf Build platform inferred as: x86_64-unknown-linux Host platform inferred as: x86_64-unknown-linux GHC build : x86_64-unknown-linux GHC host : x86_64-unknown-linux GHC target : arm-unknown-linux configure: Building in-tree ghc-pwd checking for path to top of build tree... /home/parallels/code/ghc checking for gcc... gcc checking whether the C compiler works... yes checking for C compiler default output file name... a.out checking for suffix of executables... checking whether we are cross compiling... no checking for suffix of object files... o checking whether we are using the GNU C compiler... yes checking whether gcc accepts -g... yes checking for gcc option to accept ISO C89... none needed checking how to run the C preprocessor... gcc -E checking for grep that handles long lines and -e... /bin/grep checking for egrep... /bin/grep -E checking for ANSI C header files... yes checking for sys/types.h... yes checking for sys/stat.h... yes checking for stdlib.h... yes checking for string.h... yes checking for memory.h... yes checking for strings.h... yes checking for inttypes.h... yes checking for stdint.h... yes checking for unistd.h... yes checking for arm-linux-gnueabihf-gcc... /home/parallels/code/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-gcc checking for arm-linux-gnueabihf-ld... /home/parallels/code/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-ld checking for arm-linux-gnueabihf-nm... /home/parallels/code/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-nm checking for arm-linux-gnueabihf-ar... /home/parallels/code/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-ar checking for arm-linux-gnueabihf-ranlib... /home/parallels/code/tools/arm-bcm2708/gcc-linaro-arm-linux-gnueabihf-raspbian/bin/arm-linux-gnueabihf-ranlib checking for llc... no checking for opt... no checking whether #! works in shell scripts... yes checking for perl... /usr/bin/perl checking version of gcc... configure: error: Need at least gcc version 3.0 (3.4+ recommended) Regards, Miro
