I have been trying to port a plug-in that I have been writing to the latest gimp, but I have been having troubles. Firstly a lot of the constants that were defined in 1.18 are no longer defined in 1.20 for example RGB. Is this a deliberate change, I find it a strange thing to remove from the header. What approach should I be using to deal with this? I have also had problems with the plug-ins executing because the libgimp.o... file could not be found. I even got this problem when I removed one of the standard plugins and tried to reinstall it with gimptool As all the plug-ins in are running correctly in the main gimp I must be doing something wrong. Can anyone help? I have been working with out any problems at all with 1.18 for some time. Thanks David Rohde
