This is to make explicit the conditional select of libunwind is only
needed for libopenvswitch. If we spill it over other packages, the
generated kconfig will have recursive dependency issue. 2 new patches
were made for this goal
The other thing is that "+libunwind" will cause it to be built if any of the
packages defined in this Makefile is enabled (y or m). This is at the moment
by-design of the build system.
Libunwind does not support architectures like arc. Use conditional select To
avoid (libunwind) build failures like the following,
checking for ELF helper width... configure: error: Unknown ELF target: arc
make[3]: *** [Makefile:65: /data/openwrt/build_dir/target-arc_arc700_uClibc/
libunwind-1.3.1/.configured_68b329da9893e34099c7d8ad5cb9c940] Error 1
Things like "+PACKAGE_openvswitch-libopenvswitch:libunwind" will also result in
recursive deps error for chains of 3 nodes. Kconfig construct like the
following will be made
config A
tristate
select B
depends on !(C) || (x)
config B
tristate
select C
config C
tristate
config x
bool
Other changes include
- Shared use of variable ovs__common_depends was removed
- Ovn doc build was patched out
