I published my first plugin today and, being an Ubuntu user, I also included a Linux x64 binary version. However, the first comment I received was somebody asking for a Windows binary!
Fortunately another user built it and posted a download, but it brings up the following questions.
Firstly, is there a simple way for the gimptool-2.0 under Linux to be used to cross-compile the plugin for Windows?
Secondly, considering that a GIMP plugin must conform to a specific structure and (usually) has standard dependencies, why is there not an automated build system on here to which a developer can submit their plugin source and it will provide Linux/Windows/Mac (32-bit/64-bit) binaries for users to download?
