Thank you for your assistance. I was able to properly serialize the ex class using char arrays, facilitated by the I/O capabilities of the archive class. Eric M. Collins On 12/24/06, ginac-list-request@ginac.de <ginac-list-request@ginac.de> wrote:

Would anyone be interested in helping me figure out how to serialize the datatypes in GiNaC/CLN/GMP? I've looked at the source headers for some of the datatypes and the use of reference counted pointers everywhere makes this seem like a non-trivial task.

I need to be able to pack all data relevant to a particular instantiation of a datatype (e.g. numeric or pseries), into a contiguous array. This data would then be passed to another process where it would be unpacked into a new instantiation of the same datatype.

Any help, or suggestions of where to begin looking for relevant information would be much appreciated.
