[elephant-devel] 0.6.1 / OpenMCL / BDB

[Ian Eslick]

I can get OpenMCL 1.1 to compile build and launch, but BDB cannot  
open a newly created DB in open-store-controller.  I'm wondering if  
this is due to UFFI's handling of types such that we're getting 32- 
bit instead of 64-bit pointers out of the underlying C API (int vs.  
long)?

The steps to getting this far are:
OpenMCL 1.1 for x86-64
Configure and compile BDB 4.5 with -arch x86_64
    (something like: env LDFLAGS="-arch x86_64" CFLAGS="-arch x86_64"  
configure from build_unix)
Latest Elephant 0.6.1 from CVS (as of 1/31/07)

Daniel, want to take another crack at this?

Thanks,
Ian
