             Bug #: 55465

           Summary: Name collision in C binding (calling C from Fortran)

    Classification: Unclassified

           Product: gcc

           Version: 4.7.3

            Status: UNCONFIRMED

          Severity: normal

          Priority: P3

         Component: fortran

        AssignedTo: unassig...@gcc.gnu.org

        ReportedBy: fmarti...@gmv.com





The following compile error is generated. Maybe not a bug but is passes through

the Intel compiler and I cannot see the reason why it would not compile.

Essentially I am trying to use the binding to call from Fortran the same C

function in two different ways. The interface sql_set_env_attr has two

implementations, one sql_set_env_attr_int where the parameter value is passed

as c_int and another one sql_set_env_attr_ptr where the parameter value is

passed as c_ptr.

In any case the message is somewhat misleading as it identifies the name of the

binding SQLSetEnvAttr as global body and as interface body.

Compilation diagnostics follow:





m_odbc_if.f90:168.4:



    function sql_set_env_attr_ptr( input_handle, &

    1

m_odbc_if.f90:153.4:



    function sql_set_env_attr_int( input_handle, &

    2

Error: Binding label 'SQLSetEnvAttr' in interface body at (1) collides with the

global entity 'SQLSetEnvAttr' at (2)
