I've used packetq in the past with SLES/openSUSE without issues, but currently need to build it on RHEL6. The thing is I'm getting this error:

Anybody has seen it?

Hi Ciro,
I have run into this same compile error on CentOS 6. Did you ever find a solution to it?

Hi

You can try the change below, it might be less confusing for the compiler:

@@ -82,7 +82,8 @@ Row *Table::create_row()
 {
     if (!m_row_allocator)
     {
-        m_rsize = sizeof(Row) - sizeof(Row::m_data); // exclude the dummy
+        Row *dummy=(Row*)0;
+        m_rsize = sizeof(dummy) - sizeof(dummy->m_data); // exclude the dummy
         m_dsize = m_curpos;
         m_row_allocator = new Allocator<Row>(m_rsize+m_dsize,10000);
     }

Thanks for this suggestion Per. It appears to have gotten rid of this specific compiler error. However, there are now other errors. I think this will be a whack-a-mole game, and may take several iterations to fix. I would fix it myself, but I don't know C++, so there's little I can do to fix it myself.

Anyway, it compiles well on newer gcc, so I will get newer gcc packages for CentOS 6 and try them out.
