There is no warning. But as I can see the problem is here
If erase this line
lengthBLOB=blobGet.getBinaryLength();
end just print it like
cout<<"Retrieved binary Length: "<<blobGet.getBinaryLength()<<endl;
that everything is ok. But I need this integer that blobGet.getBinaryLength()
is returning, to keep it as a value.

You're calling blobGet(), but blobGet is an unitialised variable of type
"CppSQLite3Binary" (whatever that is). Doesn't your compiler warn you
about that?
