Dear Sergey Shelukhin,
Thanks very much for your reply, and I have found out the reason.
I should put the -lthrift flag at the end of the command line, thanks to the
stackoverflow problem??
http://stackoverflow.com/questions/7337292/does-linking-switch-order-matters??
And according to my experience, a modification of Makefile is needed to make
DemoClient.cpp compile and run. Do you or some other ones have the same problem?
Thanks
yours,
Ling Kun

Democlient.cpp ?
At some point few months ago, I think I was able to make cpp sample from
trunk compile and link (against trunk).
I think one of the problems on the way was that some HBase thrift classes
got renamed between versions of thrift used before and after (in your case,
94 and current trunk).
Can you check the thrift generated code, thrift headers you use to compile,
and thrift you are actually linking against, for, respectively, usage,
declaration and definition of this ctor?
I am not sure how, you might be compiling against thrift headers of one
version but linking against a different one...
