Charm++ parallel programming system

[Jonathan Hoelzel <hoelzel2 AT illinois.edu>]

Hello,

I am working on a project using Charm++, and I have run into a compilation issue when trying to implement a templated chare.  I have attached a zip file with some example code that causes this problem.

Specifically, I get the following error when linking:

main.o: In function `_registermain()':

main.C:(.text+0x562): undefined reference to `_registerchild()'

collect2: error: ld returned 1 exit status

Looking in the child.def.h file, the '_registerchild()' method is only defined if CK_TEMPLATES_ONLY is not set when including child.def.h file.   However, if I include child.def.h again without setting CK_TEMPLATES_ONLY, then I get a similar error saying "multiple definition of 'registerchild()'".  I have been unable to work this out myself, so some help would be great.

Thanks,
