After writing a nice app that uses the Twain framework, part of image
capture, I moved to a intel based powerbook for development.
Everything compiles but the twain portions are broken only unless I
use a PPC processor as the target binary. If I select PPC and Intel
or Intel solely, the app cannot find the twain source to prepare an
image capture.
I also found that if I use 10.4 sdk this is the only case PPC version
can see the twain source when compiling on an intel machine. If I
use what I originally designed for 10.2, even the PPC version can see
the twain devices to select the source on the intel machine. I am
sure I am not the only one who has this problem as the twain.org
forum has several posts of problems. No answers of course.
Anyone run into this problem and know what is going on? At a
developer event, an Apple developer looked over the project and
thought it was a setting in XCode, but I have flipped every stone
over and spent enough time convinced something is broken with Twain,
Xcode, and Intel machines.(all part of image capture framework) It
appears the twain binary is compiled for intel, but I am wondering
what happens when a PPC driver for the scanner gets called? Could
this be the issue? Most of the drivers I have seen all look carbonish.
I have given up on reporting bugs since they never seem to address/
consider bugs I post. ie NSMailDelivery big problems two years and
no answer or recognition ie case still open( yet since the case was
opened, three or four methods were removed from the class ).
I am guessing this problem will never be address since everyone buys
a scanner, uses it a day and then chucks it. Call me a cynic but it
is a bummer when you want to move forward and 6 months of work gets
chopped and the viability of the app is in question. Does anyone
know if Twain will be supported (let's limit this to one year out)?
This is all in a Cocoa app.
Jim
