i need to add xft and utf-8 support to xmobar, so i chose to install aur/xmobar; i add two lines in PKGBUILD for that: runhaskell Setup configure --flags="with_utf8" || return 1 runhaskell Setup configure --flags="with_xft" || return 1 then i tried to build aur/xmobar, but i got the following error msg: --------------------------start of output-------------------------- Building xmobar-0.9... [ 1 of 25] Compiling Commands ( Commands.hs, dist/build/xmobar/xmobar-tmp/Commands.o ) [ 2 of 25] Compiling Runnable[boot] ( Runnable.hs-boot, dist/build/xmobar/xmobar-tmp/Runnable.o-boot ) [ 3 of 25] Compiling XUtil ( dist/build/xmobar/xmobar-tmp/XUtil.hs, dist/build/xmobar/xmobar-tmp/XUtil.o ) [ 4 of 25] Compiling Plugins ( Plugins.hs, dist/build/xmobar/xmobar-tmp/Plugins.o ) [ 5 of 25] Compiling Plugins.StdinReader ( Plugins/StdinReader.hs, dist/build/xmobar/xmobar-tmp/Plugins/StdinReader.o ) Plugins/StdinReader.hs:29:15: Ambiguous type variable `e' in the constraint: `GHC.Exception.Exception e' arising from a use of `catch' at Plugins/StdinReader.hs:29:15-78 Probable fix: add a type signature that fixes these type variable(s) ==> ERROR: Build Failed. Aborting... Error: Makepkg was unable to build xmobar package. --------------------------end of output-------------------------- whats wrong here? it seems the community/xmobar has no utf8 and xft enabled, but it's really needed for CJK users. thanks lars
