Date: Mon, 8 Dec 2008 13:47:34 +0100 From: Александър Л. Димитров <aleks.dimitrov@googlemail.com> To: arch-haskell@haskell.org Subject: Linker Scripts on Arch & GHC Hello fellow Arch-Haskellers Sorry for disturbing this peaceful list, but I only recently ran into what ultimately turned out to be a problem with Arch Linux' layout of system libraries and GHC's lacking support for linker scripts. My original bug report to the yi-devel mailing list is rather longish, so I'll just link you to it and then summarize the problem: http://tinyurl.com/6qrhnk http://preview.tinyurl.com/6qrhnk The problem: terminfo links against /usr/lib/libncurses.so, which on most distros is a symlink to something that makes more sense (like /lib/libncurses.so.5) On Arch, this is a linker script instead, which GHC cannot interpret. It thus fails with a linker error: Prelude> :m +System.Console.Terminfo Prelude System.Console.Terminfo> term <- setupTerm "xterm" Loading package syb ... linking ... done. Loading package base-3.0.3.0 ... linking ... done. Loading package terminfo-0.2.2.1 ... <command line>: can't load .so/.DLL for: ncurses (/usr/lib/libncurses.so: file too short) Gwern then kindly forwarded the Mail to Don (his response is in the above thread.) The problem with the proposed solution (for now) is that it involves manually erasing /usr/lib/libncurses.so and replacing it with a symlink. This solution has obvious flaws, of course. Most importantly, it doesn't really resolve the issue. There is at least one other package on AUR which is affected: http://aur.archlinux.org/packages.php?ID=18495 Since I have no clue about linker scripts, and no clue about GHC's linking system either, I decided to forward the issue here. It's probably unlikely that Arch will move away from linker scripts (or is it?), so the solution would be implementing (some level of basic) support in GHC? Best, Aleks PS: and thanks for your current efforts, the Haskell support was the reason for me to switch from Debian to Arch :-) From: arch-haskell-request@haskell.org Subject: confirm 2b4ccbb8a7ce56d307288059b31df5bb6be58cc7 If you reply to this message, keeping the Subject: header intact, Mailman will discard the held message.
