[dpdk-dev] How to compile and run l2fwd/l3fwd on DPDK windows?

[dpdk-dev] How to compile and run l2fwd/l3fwd on DPDK windows?

[William Tu]

Hi,

I'm able to follow the doc to run helloworld example
https://doc.dpdk.org/guides/windows_gsg/build_dpdk.html#build-the-code

I'm thinking about running l2fwd on my x710 card.
Is there any step-by-step document to follow?

So far I'm not able to compile the l3fwd and l2fwd.
meson fails for l3fwd:
c:\dpdk>meson --reconfigure -Dexamples=l3fwd build
The Meson build system
examples\meson.build:93:4: ERROR: Problem encountered: Missing
dependency "hash" for example "l3fwd"

Currently, L2fwd/ L3fwd is WIP and does not have support on dpdk master branch.

But, you can refer to draft repository and checkout windpdk-v18.08-clang.
This has a Visual Studio solution file and you'll need Clang-llvm and Visual Studio
to build the project.
You can refer to dpdk-draft-windows\doc\guides\windows.md for more details.
However, you can use Clang compiler instead of ICC.
We are working on updating the doc to change it to Clang compiler and not ICC.

Windows support is in very early stage.
A draft repository has more support:
	http://git.dpdk.org/draft/dpdk-draft-windows/?h=windpdk-v18.08-clang
