Chris, GCC uses __attribute__ extensions for such declarations as dlliimport and dllexport. http://gcc.gnu.org/onlinedocs/gcc-3.4.3/gcc/Function-Attributes.html#Function-Attributes has a section specifically on dllimport and dllexport and a comparison to the declspec() Microsoft version. As you can see, unless you are compiling under cygwin, you will need to use the __attribute__ keyword: "On cygwin, mingw and arm-pe targets, __declspec(dllexport) is recognized as a synonym for __attribute__ ((dllexport)) for compatibility with other Microsoft Windows compilers." corey On Wed, 09 Feb 2005 16:59:36 +0100, SEM GmbH <entwicklung@xxxxxx> wrote: > hello gcc-team! > > at first, I have to do a short description of our problem. > > Since about 2 years we have a existing software (developed in delphi 5) > that is currently running on windows-systems.
