Do you need to #include <vector>?

It compiled fine earlier but I've included it now.

+enum WebDuplexMode {
+    WebUnknownDuplexMode = -1,
+    WebSimplex,
+    WebLongEdge,
+    WebShortEdge
+};
+
+struct WebPageRange {
+    int from;
+    int to;
+};
+
+struct WebPrintPresetOptions {
+    WebPrintPresetOptions()
+        : duplexMode(WebUnknownDuplexMode) { }

You will want to initialize all of the members.

Thanks! Initialized everything except pageRanges based on :
