Re: [Gems-users] opal.so problem

[Dave <zhu_dave@xxxxxxxxx>]

Yes I do. Attached you will find the nm output from cache.o. I'm using gcc version 4.0.0 20050519 (Red Hat 4.0.0-8).

Thanks,

Dave

Do you have these two lines in Cache.C?

// C++ template: explicit instantiation
template class generic_cache_template;

If yes, can you dump the nm output from Cache.o to me?
