Clang 18 has become more stringent about narrowing in initializer lists,
resulting in errors when building devel/electron27:
../../third_party/webrtc/pc/legacy_stats_collector.cc:191:54: error: non-constant-expression cannot be narrowed from type 'double' to 'float' in initializer list [-Wc++11-narrowing-const-reference]
191 | {StatsReport::kStatsValueNameTotalAudioEnergy, info.total_output_energy},
| ^~~~~~~~~~~~~~~~~~~~~~~~
../../third_party/webrtc/pc/legacy_stats_collector.cc:193:8: error: non-constant-expression cannot be narrowed from type 'double' to 'float' in initializer list [-Wc++11-narrowing-const-reference]
193 | info.total_output_duration}};
| ^~~~~~~~~~~~~~~~~~~~~~~~~~
and later:
In file included from ../../cc/layers/mirror_layer_impl.cc:5:
../../cc/layers/mirror_layer_impl.h:59:40: error: non-constant-expression cannot be narrowed from type 'int' to 'unsigned long' in initializer list [-Wc++11-narrowing-const-reference]
59 | return viz::CompositorRenderPassId{mirrored_layer_id()};
| ^~~~~~~~~~~~~~~~~~~
The first batch of errors can be fixed similarly to bug 276997, by
cherry-picking <https://webrtc.googlesource.com/src/+/267f9bdd53> into the
thirdparty directory.
The second batch of errors can be fixed by cherry-picking
<https://chromium.googlesource.com/chromium/src/+/5e9fb4130a537>.

This is the FreeBSD Ports Collection. For an easy to use
WEB-based interface to it, please see:
https://www.FreeBSD.org/ports
For general information on the Ports Collection, please see the
FreeBSD Handbook ports section which is available from:
https://docs.freebsd.org/en/books/handbook/ports/
for the latest official version
or:
The ports(7) manual page (man ports).
These will explain how to use ports and packages.
If you would like to search for a port, you can do so easily by
saying (in /usr/ports):
make search name="<name>"
or:
make search key="<keyword>"
which will generate a list of all ports matching <name> or <keyword>.
make search also supports wildcards, such as:
make search name="gtk*"
For information about contributing to FreeBSD ports, please see the Porter's
Handbook, available at:
https://docs.freebsd.org/en/books/porters-handbook/
NOTE: This tree will GROW significantly in size during normal usage!
The distribution tar files can and do accumulate in /usr/ports/distfiles,
and the individual ports will also use up lots of space in their work
subdirectories unless you remember to "make clean" after you're done
building a given port. /usr/ports/distfiles can also be periodically
cleaned without ill-effect.
