Hello, I attempt to test new build system on solaris/x86 platform and after applying patch from here: http://hackage.haskell.org/trac/ghc/ticket/2951 I've been able to boot and configure the tree. On the other hand build alone fails with: checking for unistd.h... yes checking editline/readline.h usability... no checking editline/readline.h presence... no checking for editline/readline.h... no checking editline/editline.h usability... no checking editline/editline.h presence... no checking for editline/editline.h... no checking readline/readline.h usability... no checking readline/readline.h presence... no checking for readline/readline.h... no checking for sign of read_history result on error... negative checking for rl_completion_matches... no checking for completion_matches... no configure: error: editline not found, so this package cannot be built See `config.log' for more details. gmake[1]: *** [libraries/editline/dist-install/package-data.mk] Error 1 gmake: *** [all] Error 2 karel@silence:/tmp/ghc-new-build-system$ Do you have any idea how to proceed or what exactly to install? Thanks, Karel
