Hi All,
I am attempting to compile the rss epbf program dpdk and I am getting too
much compilation errors, is there anything specific that I need to
configure when compiling?
I am running the following line:
clang -O2 -emit-llvm -c tap_bpf_program.c -o - | llc -march=bpf
-filetype=obj -o tap_bpf_program.o
I think it is due to some misconfiguration of
The errors I am getting:

Sorry I have accidentally sent my last email without finishing it.
I believe it is due misconfiguration of the linux headers and their
inclusion. Anyone else faced these errors?

Hi Sameeh,
RSS ebpf source code compilation is planned for dpdk next releases.
In order to compile the current tap_bpf_program.c code you will need definitions found in iproute2:
https://git.kernel.org/pub/scm/network/iproute2/iproute2.git/
1. Please clone iproute2 tree and make it accessible to your build environment, say under directory <iproute2_root_tree>.
2. Please add "bpf_api.h" file inclusion in tap_bpf_program.c (following tap_rss.h inclusion, see [1])
3. When running the clang command please include the iproute2 include directory, for example,
clang -I <iproute2_root_tree>/iproute2/include -O2 -emit-llvm -c tap_bpf_program.c -o - | llc -march=bpf -filetype=obj -o tap_bpf_program.o
That’s all is needed.

I have just tested this and this indeed solved the compilation errors!
It'll be great if you'll add them to the documentation as it is misleading
and not up-to-date :)
