Package: libpng12-dev
Version: 1.2.8rel-5
Severity: important
libpng12 doesn't export the png_save_uint_16 function, but this function
is declared in a public header file (png.h). This is important because
it is part of the public API, but can't actually be used.
This was stopping the sng package from building because it used this
function. (See soon-to-be-closed bug #339889). I worked around this by
not using the function, but replicating what it did (since it was simple).
Anyway, for this bug to be closed, either this function needs to be
exported, or if the function really is not supposed to be used, the
declaration needs to be removed from the public API and not listed in
png.h.
Thanks! =)
