Problem in exporting static function in win32 dll

Hi All,

I have a function in my C file. This is a static function. I want to export this function in the windows DLL. for exporting this function i have it in .h file as

static int SPLIBRSYNC_API SayHello(int i);

If i compile my code without the .def file. it compiles successfully. No as i have to export this function. i put the entry of this function in the .def file as

LIBRARY MyDll

EXPORTS
SayHello @1

Now after adding the .def file, when i compile the project, i get the linker errors as

SPLibrSync.def : error LNK2001: unresolved external symbol SayHello
Debug/SPLibrSync.lib : fatal error LNK1120: 1 unresolved externals
LINK : fatal error LNK1141: failure during build of exports file

if i remove the static keyword from the .h and .c file. The project compiles successfully. So what might be the problem with static keyword for exporting.

Please help

Thanks

the problem is that the static function is only visible inside the current c/cpp file
So it obviously cannot be visible outside the dll

Hi Vart,

Thanks for the prompt reply,

So what should i do to export the static function. Can i export it?

No you can't. Remove static

static means internal linkage, i.e. the function is not supposed to be visible outside its compilation unit. Trying to export it is a direct contradiction.
