Hi all,

   Has anyone been able to build dolfin with Petsc *and* Hypre on  
MacOSX 10.4 (I know it has been done for 10.5)?

   I've successfully built dolfin against  a vanilla Petsc-2.3.3-p13  
and am trying to extend it to use AMG from Hypre and have run into  
some dynamic library issues.

1) I can build Petsc with hypre-2.0 just fine (with either shared or  
static libraries for Petsc, hypre is always libHYPRE.a)
2) if I try to rebuild dolfin against this petsc (after removing the  
petsc.pc file) scons fails to create a packageconfig file petsc.pc
3) I can edit the vanilla petsc.pc to add -L/path/to/hypre  -lHYPRE  
and rebuild dolfin. This has been shown to work on 10.5 (Leopard) but  
I seem to have issues in 10.4.
    When building libdolfin.dylib, I get the ld error

mpicxx -o dolfin/libdolfin.dylib -framework vecLib -dynamiclib - 
undefined dynamic_lookup dolfin/common/TimeDependent.os ... lots and  
lots of libraries

ld: common symbols not allowed with MH_DYLIB output format with the - 
multi_module option
/Applications/petsc/petsc-2.3.3-p13/externalpackages/hypre-2.0.0/ 
macosx-gnu-local-dolfin-O/lib/libHYPRE.a(globalObjects.o) definition  
of common _msgBuf_dh (size 1024)
/usr/libexec/gcc/i686-apple-darwin8/4.0.1/libtool: internal link edit  
command failed
scons: *** [dolfin/libdolfin.dylib] Error 1
scons: building terminated because of errors.


I suspect the problem lies with the Hypre libraries and MacOSX and  
not Dolfin or PETSc per se, but the issue is getting AMG/Petsc  
support into dolfin on MacOSX.  Any known fixes, work arounds (beyond  
buying a linux box ;^)?

all help greatly appreciated
cheers
marc
