[Haskelldb-users] Intel Mac Build Problems

[Kelly N. <ni...@ke...>]

Hi folks,

I haven't had very much luck building haskelldb on an intel mac. The error
that finally put an end to forward progress is copied below. I am running
ghc-6.6 and ./configure seemed to like my setup (although I did have to run
./configure --build i386-apple-macosx8.8.0, since config.guess couldn't make
out my mac). The summary given by ./configure was:


HaskellDB will support:
-----------------------

GHC:               yes
  HSQL:            yes
    ODBC:          no
    MySql:         yes
    SQLite:        no
    PostgreSQL:    no
  WxHaskell:       no
Hugs:              no
  HSQL:            no
    ODBC:          no
    MySql:         no
    SQLite:        no
    PostgreSQL:    no
  WxHaskell:       no

The actual error emitted during make.

If anyone has any thoughts, I would greatly appreciate the help.
