Thanks for noticing.
That line is bogus. I added it together with some other debug code,
while I was trying to understand why the newer libdvbv5.mo was not
being used on my system.
There's actually an weird issue that was happening on my system.
Here, I installed v4l-utils at the /usr/local prefix.
For the dvbv5-scan, it should load the v4l-utils.mo translation.
It did it right:
open("/usr/local/share/locale/pt_BR.utf8/LC_MESSAGES/v4l-utils.mo", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/local/share/locale/pt_BR/LC_MESSAGES/v4l-utils.mo", O_RDONLY) = 3
But, for the library, it looked only at the /usr prefix:
open("/usr/share/locale/pt_BR.utf8/LC_MESSAGES/libdvbv5.mo", O_RDONLY) = -1 ENOENT (No such file or directory)
open("/usr/share/locale/pt_BR/LC_MESSAGES/libdvbv5.mo", O_RDONLY) = 3
So, it was loading an old copy of the translation messages.
Btw, there is a similar issue I noticed a few weeks ago,
related to pkg-config: it is also not looking for libdvbv5.pc
at /usr/local prefix. I also had to manually force pkg-config
to also seek under /usr/local by setting an env var:
export PKG_CONFIG_PATH=$(pkg-config --variable pc_path pkg-config):/usr/local/lib/pkgconfig
I didn't try to identify the reason for that yet. I *suspect* that
this is not related to v4l-utils autoconfig, but, instead, to some
patches that are missing when pkg-config and glibc search patches
on Fedora 23.
In any case, I'm c/c Gregor. He may know a little bit more about
such issues.
Anyway, with regards to the unused code, just fixed it upstream.
Thanks,
Mauro
