Package: gputils
Version: 0.13.1
When I use gputils 0.12.4-1 to compile my program I can include a .o
file made from a .asm file which specifies the PIC18F458 configuration
locations. This produces appropriate output in the resulting .hex
file.
When I use gputils 0.13.1-1 to do the same thing, the ID location data
is simply omitted. This is a critical failure in my application - it
maes 0.13.1-1 unuseable for me.
See the transcript below.
Note that in both cases I'm using a `backport' - that is, I rebuilt
the package on a system running woody. This was trouble free and I'm
confident that isn't the problem. If you really think it is then I
could try the supplied 0.13.1-1 .deb on a system running testing.
I suspect that this bug may need to go upstream, but I'm reporting it
here first so that you can decide what to do with it.
Thanks,
Ian.
