Description Martin Jambor 2024-06-04 15:34:25 UTC 
GCC 14 newly by default treats as errors a number of situations which
before were only warnings.  For more information see
https://gcc.gnu.org/gcc-14/porting_to.html and meta bug #1220571.

Because of this, package vde2 fails to compile.  This can be seen online
at:
https://build.opensuse.org/package/live_build_log/openSUSE:Factory:Staging:Gcc7/vde2/standard/x86_64

It can be reproduced locally with command: osc build --clean
--alternative-project home:rguenther:nextgcc

We probably need
https://github.com/virtualsquare/vde-2/commit/f86c725db59d0e0ec9967f7af2703328a96ac993
and perhaps more.


The (first) error (that halts the build) is:

[   32s] wirefilter.c: In function ‘markov_compute’:
[   32s] wirefilter.c:136:13: error: type of ‘i’ defaults to ‘int’ [-Wimplicit-int]
[   32s]   136 | static void markov_compute(i)

The single issue has already been fixed upstream, I have backported the fix and created https://build.opensuse.org/request/show/1187553
