(crosspost from haskell-libraries)
Hello all, again.
Meanwhile I've been able to install this package without too much
trouble on a Linux system. Unfortunately MacOSX is still a problem.
Both on Linux and Mac I installed the Berkeley DB and DBXML packages
with `--prefix=/usr' so all include files and libraries end up in a
standard place.
Also both on Linux and Mac I installed the Haskell BerkeleyDB bindings
just with:
cabal install BerkeleyDB
Because the DBXML include files are installed under /usr/include/dbxml/
*.hpp and the BerkeleyDBXML binding accesses them without this prefix
I did:
cabal install BerkeleyDBXML --extra-include-dirs=/usr/include/dbxml
On both system installation is not a problem. Compiling the demo
`adventure' included in de bindings distribution works fine on Linux
but fails on MacOSX. The errors are the ones in my previous mail
below. A full hpaste of it can be found here[1].
Any idea where the difference in behaviour comes from on these
platforms and how to fix this? Unfortunately, my knowledge of the c++
toolchain and Haskell FFI bindings using these is _very_ limited.
Thanks,
Sebastiaan

Hello all,
After manually specifying where to find the appropriate include and
library directories for the dbxml distribution, I succeeded to
install both the BerkeleyDB and the BerkeleyDBXML Haskell bindings.
They both nicely show up in `ghc-pkg list'.
But when I try to compile my own test or the demo program included
in the BerkeleyDBXML package it will kindly present me a dozen or so
pages of linking errors. The top lines are:
Undefined symbols:
"std::basic_string<char, std::char_traits<char>,
std::allocator<char> >::_Rep::_M_destroy(std::allocator<char>
const&)", referenced from:
__xmlDocument_setContent in
libHSBerkeleyDBXML-0.6.2.a(dbxml_helper.o)
...
Do I have to tell GHC where to find the original dbxml libraries
when compiling my BerkeleyDBXML aware Haskell programs?
Small system overview:
- Mac OS X 10.5.7
- GHC 6.10.3
- BerkeleyDB 0.7.1
- BerkeleyDBXML 0.6.2
- gcc/g++ 4.0.1
Any clue on how to fix this?
Thanks,
