Question

I tried to use the boost lockfree library. However, there is an error invalid application of ‘sizeof’ to incomplete type ‘boost::STATIC_ASSERTION_FAILURE<false>’ when I set the template parameter to user define type.
Is there any to resolve it?

typedef struct TMsgBuffer
   {
      char m_puBuffer[512];
      size_t m_iBufferLen;
   } tMsgBuffer;

boost::lockfree::fifo<tMsgBuffer> fifo;

Answer 1

STATIC_ASSERTION_FAILURE arises from a BOOST_STATIC_ASSERT. I suspect Boost.Lockfree has some size limit on the elements of the fifo. Try again with a smaller UDT.

It may also be the case that Lockfree only works with standard types, so no UDT’s will be accepted. If that’s case you need to store a pointer instead of the actual structure.
