that is intresting, i did an equery on my systems for that ivtv file i get
[ Searching for file(s) /usr/include/linux/ivtv.h in *... ]
media-tv/ivtv-1.0.3-r1 (/usr/include/linux/ivtv.h)
try a different (step down or step up) kernel/ivtv version could be bugs
in the ebuild not putting the ivtv.h file where its needed, wouldnt be a
first.
on one of my systems i have the 2.6.25 kernel i had a 2.6.24 kernel and
i had to mod the ivtv-1.0.3 ebuild to build on the kernel (there was no
package for 24 at the time) and it worked then, so that would be
something else you could try, all you would need to do is edit
/usr/portage/media-tv/ivtv/ivtv-1.0.3-r2.ebuild
and change:
if ! ( kernel_is 2 6 22 || kernel_is 2 6 23 );
to: if ! ( kernel_is 2 6 22 || kernel_is 2 6 23 || kernel_is 2 6 24 );
then run #ebuild /usr/portage/media-tv/ivtv/ivtv-1.0.3-r2.ebuild digest
and then emerge =ivtv-1.0.3-r2
if you want the changes not to be over written, make a directory called
media-tv in your overlay, and copy the ivtv folder to there and work
from there and edit accordingly.
at the time the package was listed at for 22 kernels and up and there
were no newer packages. after adding support for 24 it worked fine. the
ivtv-1.1.0+ packages could be broken, they are still masked anyway.
