Hi,

Thank you for your reply!
I still have some questions.
1. Can c++ interpreter be used in product version?
2. Can c++ interpreter be used in 64 bit machine with Linux OS.

Thanks again.

Both answers should be yes.  I don't see a reason why it shouldn't work.
Have you tried it?

Hello,
When I added  CC_INTERP=1 as make option. I got following error :

        }

How can I fix it?
Thanks a lot!

I recently tried to build the C++ interpreter and it worked.  You should
try a more recent build than b24.  If that fails too, please file a bug
report.
