Instead, the usual approach is to define a macro that expands to _ _declspec(dllexport) when building your DLL and to However, since it is difficult to maintain two separate versions of the same
COMPILE FILES INTO A DLL FILE CODE
One approach would be to use two sets of headers: one for building yourĭLL and the other for compiling code that uses your DLL. _ _declspec(dllimport) when compiling code that _ _declspec(dllexport) when building your DLL and _ _declspec(dllimport), you must be sure to use If you choose to use _ _declspec(dllexport) and _declspec(dllimport) is not part of the C++ language, but an extension

_decl-spec(dllimport) is used exactly like the attribute _ _declspec(dllexport), discussed earlier. Just as with exporting symbols, I recommend that you use the attribute _ _decl-spec(dllimport) in your source code instead of using. Library to the linker when linking code that uses your DLL. _ _declspec(dllimport) and pass an import In the headers included by source code that uses your DLL, use the attribute In some cases, however, there is no alternative but to make all symbols

Some Unix toolsets also offer this flexibility this is trueįor recent versions of GCC on several platforms, for Metrowerks on Mac OS X, and for Imported when an executable or dynamic library that uses theĭynamic library is built.

With most Windows toolsets, in order for a symbol defined in a dynamic library to beĪvailable to code which uses the dynamically library, it must be explicitlyĮxported when the dynamic library is built and It also makesīuilding and using dynamic libraries more complex, however. Library’s public interface, and it often provides superior performance. Being able to determine which symbols should be visible on a case-by-caseīasis is generally advantageous it gives a programmer more explicit control of his Some platforms, all such symbols are automatically accessible to code which uses aĭynamic library other systems offer programmers fine-grained control over which symbols areĪccessible. This will generate the import library libgeorgeringo.lib.ĭynamic libraries can contain the definitions of classes, functions, and data. Finally, enter the command: > implib -c libgeorgeringo.lib libgeorgeringo.dll This will generate the dynamic library libgeorgeringo.dll. Next,Įnter the command: > bcc32 -q -WD -WR -elibgeorgeringo.dll george.obj ringo.obj georgeringo.obj These three commands will generate the objectįiles george.obj, ringo.obj, and georgeringo.obj.
