SQLDA is the name of a structure and it is uppercase in the header file. sqlald() is a function which initializes an SQLDA structure.
The error messages you've shown above seems to indicate that you are doing a C++ compile since the name is mangled. Are you sure that you are doing a precompile with mode=cpp?
Beyond that , show your source code so that we can see what is going on.
