code a Duan Hong are defined as follows:

# define CLASS_THREAD (c, x) \
Rp: : Hal: : Thread: : create_member & lt; C., & amp; C: : x> (this)

For the younger brother didn't understand what that means, the replacement of grammar or see for the first time, also please give some directions passing down,,,,

VS the IDE in don't understand the symbol on the right mouse button, choose to define,

[ask] "_cachethread=CLASS_THREAD (RPlidarDriverSerialImpl _cacheCapsuledScanData);" , dating back to the thread. H header file, macro definition about CLASS_THREAD:

"# define CLASS_THREAD (c, x) \
Rp: : Hal: : Thread: : create_member & lt; C., & amp; C: : x> (this) ", will replace, find the right hand side _cachethread statement seems to do not conform to the grammar, don't know whether our replacement process is wrong,

Can you tell me whether the replacement process is wrong?
_cachethread=rp: : Hal: : Thread: : create_member & lt; RPlidarDriverSerialImpl, & amp; RPlidarDriverSerialImpl: : _cacheCapsuledScanData & gt; (this);

Compiled an ERROR result is an INTERNAL COMPILER ERROR, compile the INTERNAL ERROR,

Assignment statements, please the equals sign expression down on the right side of a comma, the semicolon at the end, this structure can compile? A=B c; Really don't understand!
