wxWebView compile issue on Ubuntu

I have been unable to compile wxWebView in my C++ code. 

#include <wx/wx.h>
#include <wx/wxhtml.h>
#include <wx/webview.h>

class MyFrame : public wxFrame
{
public:
    MyFrame();

    wxPanel    *panel;
    wxBoxSizer *topsizer;
    wxMenuBar  *menubar;
    wxMenu     *file;
    wxWebView  *webView;    // <---- HERE
    wxString    editorURL;
};

I get the following compiler errors (snippet):

g++ -c `wx-config --cxxflags` -o helloworld.o helloworld.cpp
helloworld.cpp:20:5: error: ‘wxWebView’ does not name a type; did you mean ‘wxWeakRef’?
 wxWebView  *webView;
 ^~~~~~~~~
 wxWeakRef

Some more information on system configuration:

  • wxWidgets 3.0
  • Ubuntu 18.04
  • Included web view file: wx/webview.h

The only thing I can think of is I am missing a package in apt-get or I have conflicting packaging. 

$ dpkg -l | grep webview
ii  libwxgtk-webview3.0-gtk3-0v5:amd64         3.0.4+dfsg-3                        amd64        wxWidgets Cross-platform C++ GUI toolkit (GTK+ 3 webview library runtime)

If you can help me figure out which packages I need for wxWebView to compile and what do I need to update in the Makefile to get it to compile.

Solution

  • It looks like your version of wxWidgets was built without wxWebView support. You can check it by greeping for wxUSE_WEBVIEW in the setup.h file included in your wxWidgets package.

    If this is indeed the case, you will need to build your own version of the library. Luckily, this is as simple as the usual ./configure && make under Unix (you don't even need to install it, although you may do it, of course).

    Last but not least: don't forget that you need to explicitly ask for webview library when using this class, i.e. use wx-config --libs std,webview instead of just wx-config --libs.
