解决方法：

Hi
To resolve this just replace variable m_data to some other name say u_data in qstringbuilder.h This will resolve ur issue
The peoblem is coming as in vxworks mbuf.h m_data is already defined as 
#define m_data mBlkHdr.mdata in So its taking this defination and trying to look out for mBlkHdr.
