[Mingw-users] anyone building Photoshop plugins with mingw?

[Toby T. <tob...@te...>]

Hi list,

I've spent quite a few dozen hours trying to track down a problem with 
Photoshop plugins built for Windows. It was a problem that manifested 
itself with a CodeWarrior 7 build and in fact this was the reason I 
began using mingw, to see if the same issue arose.

I have source to plugins which build and run perfectly under MacOS, and 
build for Windows with CW7 and mingw. On invoking the plugin in 
Photoshop for Windows (this has been tested on 2 different PCs), the 
plugin is entered and exited several times as expected, after which an 
invalid page fault invariably occurs in Photoshop. I have created a 
simple test case for this problem and fruitlessly combed its code for 
bugs which might cause this. My conclusion is that build settings are 
probably at fault (or Photoshop 5.0 has a bug).

The main entry point is documented to need stdcall conventions and this 
has been set in the source along with a corresponding EXPORTS 
definition.

Can anyone provide a working example of a Photoshop plugin built with 
mingw (or any Win32 development system)? Or should I post the complete 
test project for someone to check build settings and possibly try 
running in a different version of Photoshop for Windows?

regards
Toby
