Hi all,
apparently the gwenview code includes some copied source files from qt3.
At least compiling it against libpng-1.4.2 fails with the same errors as qt3 did. Parts of the patch for qt3 from the
kde-sunset overlay can be applied to gwenview as well.
I modified it a bit and attached it to this email. Place it in the files dir and change the "PATCHES" variable in the
ebuild as follows and gwenview should compile again.
PATCHES=(
"${FILESDIR}/gwenview-1.4.2-exiv2.patch"
"${FILESDIR}/gwenview-1.4.2-desktop-file.diff"
"${FILESDIR}/gwenview-libpng14.patch"
)
Best regards,
Jens
