Yet strangely, the last upload was Sun Apr 19 21:42:04 UTC 2009 and hackage claims it builds without failure with ghc-6.10. And in fact it builds just fine for me, so maybe it is worth finding out why it doesn't build for you. Are you using ghc-6.10.4 and the latest version of cabal? I get:

ghc --version The Glorious Glasgow Haskell Compilation System, version 6.10.4

cabal --version cabal-install version 0.6.2 using version 1.6.0.3 of the Cabal library

cabal install greencard

i am stuck with a linker error in greencard, and haven't found anything online, so i am addressing you for fresh ideas. as soon as i get this sorted out, i will try to turn the answer into a patch that you can consider for the next release.

...

the errors about no-prune-tydecls are easy enough to fix:

...

$ diff -r greencard-3.0.3{,-patched} diff -r greencard-3.0.3/examples/Gdbm/Makefile greencard-3.0.3-patched/examples/Gdbm/Makefile 28d27 < HC_OPTS += -fno-prune-tydecls diff -r greencard-3.0.3/lib/Makefile greencard-3.0.3-patched/lib/Makefile 6c6 < GHC_OPTS = -cpp -fglasgow-exts -fno-prune-tydecls ---

...

GHC_OPTS = -cpp -fglasgow-exts $

...

this helps, but the linker errors are unrealted, and i don't know what to make of them. (I guess I should study how ghc generates C code at this point? it does feel like something obvious...)

Yes, it works: $ greencard -V greencard, version 3.00 (Daniel: You were right; I made the mistake of following the instructions in the README :). Now I've finally switched to Cabal, and that did the trick. Bulat: Yes, I am aware of all the other projects, but greencard seems to be a front-end to FFI, and it looks alive enough to me right now, right?) (Btw the "report-bugs-to" e-mail doesn't work.) (Btw2: diff -r cabal-install-0.6.2/bootstrap.sh cabal-install-0.6.2-/bootstrap.sh 166c166 < dep_pkg "parsec" "2\." ---

dep_pkg "parsec" "3\."

shouldn't be a problem, right?) Thanks everybody, Cheers, Matthias On Wed, Sep 02, 2009 at 11:41:34PM +0200, Daniel Fischer wrote:

He used make, not cabal. My guess is that the makefiles haven't been updated because we now have Cabal and cabal. Formerly, Text.PrettyPrint.HughesPJ was in base, now it's in pretty, since --make is none of the HC_OPTIONS in the makefiles, ghc can't find HughesPJ, thus the linker errors.
