2nd attempt (this time from my subscribed email address):
in the course of packaging gmerlin-avdecoder i came across a small issue
with the exported symbols of the library.
debian keeps track of all those symbols and if symbols vanish, the
policy requires that the library pkgname changes (e.g. libgmerlin-avdec1
- -> libgmerlin-avdec2)
we are building on a package for 1.0.1 and have updated to 1.0.3
even with this very micro (in version-numbers) update, some exported
symbols vanished (e.g. "bgav_options_set_seamless")
now i believe, that these symbols are not meant to be "exported" anyhow,
as they do not show up in any public headers.
in order to make upgrading more seamless, i would like to prevent any
non-public symbols to be exported.
i notice that there is already a check for gcc visibility declarations
("-fvisibility=hidden") in gmerlin-avdec, which seems to be the simples
way to go.
unfortunately, the results of the test are nowhere used (only the
LIB_CFLAGS variable is updated, but it is mentioned in no Makefile)
is there a reason for this? (e.g. did it break something?)
