[Boost-users] [serialization] Can't compile archive I/O

23 Dec 2005

      I thought I had this working once after I found I needed the NVP wrappers
for XML archives.  Now the problem is back.  Below is a highly simplified
version of the problem followed by the compiler error output.  I can't make
heads or tails of the error messages.

Anyone have any ideas?
