Make download fails on qosify

[amhairghin]

Hi, I am trying to compile OpenWRT to add V2.0 support for the Cudy WR1300 but it always fails me at the same point:

make[1]: [package/Makefile:115: package/network/config/qosify/download] Error 2 (ignored)
make[2]: Entering directory '/home/ogarcia/openwrt/package/network/config/qosify'

	mv /home/ogarcia/openwrt/tmp/.ver_check /home/ogarcia/openwrt/staging_dir/toolchain-mipsel_24kc_gcc-11.3.0_musl/stamp/.ver_check; \
}

The dependency (clang) is perfectly installed, but just to avoid errors I am using a virtual machine with Debian as detailed in the Quick image building guide.

Any ideas?

Install clang and llvm. They are different packages

[amhairghin]

Both are installed:

$ dpkg -l clang llvm

The error is clear though, right from your paste:

/home/ogarcia/openwrt/include/bpf.mk:70: *** ERROR: LLVM/clang version too old. Minimum required: 12, found: .  Stop.

See:

Qosify: new package for DSCP marking + cake

Thanks for the hint. That approach makes it really easy to include qosify in a build. Documenting the steps for others: download the llvm-bpf-13.0.0.tar.xz from your router's target downloads to your buildroot. E.g. https://downloads.openwrt.org/snapshots/targets/ipq806x/generic/llvm-bpf-13.0.0.tar.xz extract the files into the buildroot: tar -xvf llvm-bpf-13.0.0.tar.xz Change toolchain option to use a prebuilt LLVM toolchain, and enable qosify. I only needed to add these two lines in…

@amhairghin

bash: line 1: /home/ogarcia/openwrt/staging_dir/host/llvm-bpf/bin/clang: No such file

pls look at this line - build system looks for clang binary in the wrong place

I`m not as keen as I should to fix the test in Makefile, so I fixed this issue on my side just with creating symlink

ln -s /usr/bin/clang-12 /home/ogarcia/openwrt/staging_dir/host/llvm-bpf/bin/clang

and before I had to

mkdir -p /home/ogarcia/openwrt/staging_dir/host/llvm-bpf/bin/

(and yes, apt-get install clang-12 llvm-12)
