I was upgrading happstutorial.com to ghc 6.10.1 when I came across a
cabal install issue.
Somewhere in day 1 (probably as a HAppS dependency), HaXml 1.13.1 got installed.
On day 2, I wanted the latest version of HaXml (1.19.4), a dependency
for for xml-parsec.
cabal install HaXml gave me: already installed.
cabal upgrade HaXml gave me: some installing action, but in the end I
wound up with 1.13.1 again.
cabal install HaXml-1.19.4 gave me what I want, the latest version.
But even then, when I do cabal install xml-parsec I get
Text/ParserCombinators/Parsec/XML.hs:18:7:
Could not find module `Text.XML.HaXml.Posn':
it is a member of package HaXml-1.19.4, which is hidden
The cabal file has
Build-Depends: base, parsec, HaXml
>ghc-pkg latest HaXml says
HaXml-1.19.4
Even after ghc-pkg hide HaXml-1.13.3
I get the same result, so I'm not even sure if the problems I'm having
are a result of the having two versions of the same package installed.
This is a bug right?
Any advice on how to get xml-parsec installed?
thomas.
