Ok. Assuming you are using 3.10p. : The problem I am having is that the c++ libraries make use of C++ library : functions (like printf) Actually, printf is a C library function, in C++ you would use the cout stream. : and when I link using the Gnat ada compiler I get : undefined references to a host of things (like _imp__fprintf). : I think that I want to add to this a library to resolve the missing : declarations but I am not sure what the library is. : Is this library available within gnat? Since you are calling a C library function, it tries to link to the MS C runtime DLL import library. GNAT links in the gcc style import library to this dll, which has a different format, so, the function is not found. The easiest way out is to recompile your C or C++ code using gcc. (if it is C code, the C compiler is included with gnat). If that is not possible, recompile the C++ code as a dll and import this through a package.
