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...

It could be that the "DllExport" is not defined anywhere. -Walter

Thanks, that was the problem because it was wrapped in a _MSC_VER define.
