Hello,
recently I've found out that my solaris-based GHC buildbot is completely unusable since it always (when it get to, which means it does not fail with usual magic number mismatch: old/corrupt interface file?) fails with:
ghc-stage2: mkTextEncoding: invalid argument (Invalid argument)
So that's when it calls iconv_open with the names of some text encodings. Apparently that is failing. You should be able to confirm this with some tracing.
I've even tried to update my building GHC from 6.8.3 to 6.10.4, but it still does not help.
No, it wouldn't.
Since I would really like to resurrect my GHC buildbot, do you have any idea how to fix this issue?
Dig into base/GHC/IO/Encoding/Iconv.hs mkTextEncoding function where it calls iconv_open, see what it's being called with. In particular check if HAVE_LANGINFO_H is getting defined. If it's not then the code assumes GNU iconv.
PS: for reference, please have a look at http://darcs.haskell.org/buildbot/all/builders/kgardas%20head
See also the http://darcs.haskell.org/buildbot/head/builders/sparky%20head Which is running Solaris 10 on sparc and seems to be working fine. Duncan
