These error messages aren't very illuminating to me, since they're in 
Chinese.  It might be sufficient for you to reset your environment 
variable `LANG' to `en_us' temporarily to have the error messages 
output in English.  Otherwise, GCC might have an option for this.

However, they all seem to involve template functions;  some
defined by me, others by the Standard Template Library.  As far as
the ones defined by me are concerned, it's possible that the compiler 
isn't finding the header files, which contain the definitions and 
the declarations for instantiation for the non-class template 
functions.  Are you using the right directory for the `prefix' argument 
when you call `configure'?  You should be in 
`/home/hongyi/Desktop/3DLDF-1.2.0.0/' when you do this and 
this directory should be the prefix argument to `configure', i.e.,
`configure --prefix=/home/hongyi/Desktop/3DLDF-1.2.0.0/'.
I really think the compiler should be finding these headers, though.

If this doesn't fix the problem, then you should check
whether the template functions from the Standard Template Library 
can be used in a trivial C++ program.  If not, then there's something 
wrong on your system.

The following example will do.

Please send me the terminal output if you have any more problems.  
I'd also appreciate it if you'd let me know if it does work.
