I'm looking to try and create a plugin for some C++ code with Xojo, being a noob I figured I would start small. Did some Googling and found that not much exists and what does is fragmented. I did purchase Eugene Dakin's e-book (updated last in 2015) and while it did help a bit I could not get his simple "FirstPlugin" working.
I was able to create a dll using VS2017 and his instructions, I then stumbled as dropping the DLL into the Plugins directory isn't what's needed, after some more digging I found out how to package the DLL (PluginPackaging.rtf) as a xojo_plugin.
Now the sample Project for FirstPlugin can't find the "AddTwo()" method from the example. Any thoughts on where to look next would be appreciated, there were no errors when I started Xojo but I guess it's possible the plugin wasn't loaded?
I'm running Xojo 2018r4 currently.
