I tried the current code and was able to compile it. Is there some setting in
the connection I need to activate the resize feature?
I got this messages in the log:

2nd update: I uncommented the check and it works now:

BTW, looking back, this is somehow funny: "it's going to have to be something
that we detect the capability (presence of that particular function) within the
library and enable or disable at compile time, so that we don't break
compatibility with older versions of the library."
Anyway, without the check on width or height not being 0, the version and your
solution works very well for me. Thanks!

> Add auto resize to VNC sessions

> Key: GUACAMOLE-1196
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-1196
> Project: Guacamole
> Issue Type: Improvement
> Components: Documentation, VNC
> Reporter: Markus Bonet
> Assignee: Nick Couchman
> Priority: Minor
> Fix For: 1.6.0

> As discussed on the mailing list:
> {quote}
> I'm running a TigerVNC session on the server where Guacamole is installed. If
> I connect with the TigerVNC viewer there is this nice feature that the remote
> desktop is automatically resized if the viewer window is resized, like this
> if offered with RDP already.
> Is there a configuration how to achieve this with a Guacamole session as well
> for my VNC connection?
> {quote}
> Historically, this could not be done without corresponding support within
> libvncclient. This should now be possible through handling the required
> message type ({{SetDesktopSize}}):
> {quote}
> Unfortunately my team had to come up with a home baked solution for this
> about 2 years ago. But it involved hacking up libvnc.
> BUT, I think it is feasible to submit a feature request for it because now
> libvnc recently tagged a new version that includes the message type that
> guacamole needs to do this:
> Tag: https://github.com/LibVNC/libvncserver/releases/tag/LibVNCServer-0.9.13
> New message:
> https://github.com/rfbproto/rfbproto/blob/master/rfbproto.rst#setdesktopsize
