The PKGBUILD of VLC 3.0 patch the ./configure and remove -Werror-implicit-function-declaration
This warning can be fix differently and more nicely

Additional info:
* package version(s) : vlc 3.0.0-1 staging


sed -e 's|-Werror-implicit-function-declaration||g' -i configure


sed -e 's|FRIBIDI_NO_DEPRECATED|FRIBIDI_DEPRECATED|g' -i modules/text_renderer/freetype/text_layout.c
This task depends upon

Can you be more verbose about why FRIBIDI_DEPRECATED should be used in text_layout.c?
Comment by Jan de Groot (JGC) - Friday, 23 February 2018, 19:47 GMT
vlc uses a deprecated function that is not declared without FRIBIDI_DEPRECATED. GCC warns about this. I think it's better to fix a warning instead of hiding it.

Technically FRIBIDI_DEPRECATED does nothing, this is just a good unique name in order to replace FRIBIDI_NO_DEPRECATED.
But if you declare FRIBIDI_NO_DEPRECATED it will not include "fribidi-deprecated.h" from "fribidi.h"

-Werror is a filthy, disgusting habit and the upstream developers should be reprimanded for using it in release archives. Providing a warning is one thing, as is using -Werror via environment CFLAGS for testing purposes, for example using Travis environment variables. Breaking downstream builds by distro developers or just random users, because the project uses -Werror without actually fixing warnings, is pretty stupid.

We're not "hiding" warnings. Warnings are, well, warnings. They exist to be looked at in build logs. Error-on-warnings is only useful in a very strictly limited situation, that being a desire to get immediate alerts when warnings exist, for development purposes.
