Build error on Entware

[Tokarak]

Scroll down for build log.

GCC10, Debian 11 build host.

I can't diagnose the problem because I'm too unfamiliar with both C and the Entware buildroot. I have both headers on the system: linux/if_arp.h and net/ethernet.h, so HAVE_GOOD_IFARP should be set. Despite that, <linux/if_arp.h> is not included.

Hi @Tokarak . I'm working on porting accel-ppp for openwrt, it is almost done and will be published soon

Could you please provide all commands from the beginning how you build for entware

Also please provide cmake output

[svlobanov]

@Tokarak you can find here dev version of accel-ppp openwrt package svlobanov/packages#20 . it's not ready yet, but at least it compiles normally

[Tokarak]

Thanks a lot, I'll look into it.
I uploaded my refreshed patches here: https://github.com/Tokarak/rtndev/tree/accel-ppp-update/accel-ppp/patches.
I'm using https://github.com/Entware/docker, following the wiki.
To replicate my environment, in the docker container run

make tools/install
make toolchain/install
make target/compile
make package/accel-ppp/compile

[svlobanov]

@Tokarak thanks for the explanation. It's fixed in #188, but I'm not sure that other maintainers accept this patch because you are using very old unsupported kernel 3.10. If other maintainers decline this patch you will need to apply this patch in your entware package

[Tokarak]

Thanks, that should work. I'll test it out.

[Tokarak]

It builds, and it runs. Thanks a lot!
