Hi, I get this error here: // // The Engine will call this function in the viewer to pass in // setup information // extern "C" { void DllExport dtsSetupViewer( ^ d:\develop\dtsearch\include\dtsviewr.h(410) : Error: voids have no value; ctors, dtors and invariants have no return value void DllExport dtsSetupViewer(dtsViewerSetupInfo& info); } Here is the declaration of "dtsViewerSetupInfo": struct dtsViewerSetupInfo { void (*logMessage)(const char *str); // adds a string to the dtSearch debug log long lzwEnableCode; dtsEngineFunctions *engineFunctions; long flags; long engineBuild; long reserved[15]; void setFlag(long f, int fOn) { if (fOn) flags |= f; else flags &= (~f); } int checkFlag(long f) { return flags & f; } // Reserved for internal use dtsAlphabet *alphabet; dtsViewerSetupInfo(); }; Does anybody know what the problem is? To which void is the compiler referring? To the return value? Somehow I have the feeling that this doesn't has to do with the struct at all... -- Robert M.

Posted in reply to Robert M. Münch | It could be that the "DllExport" is not defined anywhere. -Walter "Robert M.
