[webkit-help] WebKitPluginHost process

[Bill Appleton]

hi bill,

you have to declare core graphics AND cocoa events on startup or it won't
run -- did you do that?

i do not think you can debug the host container, is that in the webkit
source? i didn't see it

be aware that from xcode safari will launch in 32 bit mode for a 32 bit
plugin and 64 bit mode for a 64 bit plugin

if you launch safari stand-alone it will be in 64 bit mode and can run 32 or
64 bit plugins, that is where you have to "attach process" etc. to debug


thx

bill
