Re: [PATCH 2/6] Section 2: Install and Build DPDK

[Dave Young <dave@youngcopy.com>]

[-- Attachment #1: Type: text/plain, Size: 13118 bytes --]

Tyler, can you provide an example of the OS specific section/title you're
thinking would make sense to use?

Can you confirm the following?

1. The Clang-LLVM C compiler (version >= 16.0.x)
2. Meson Build system (Required version: 0.57.0)
3. Updated commands:

# Previous Command
meson -Dexamples=helloworld build
# Updated Command
meson setup -Dexamples=helloworld build

# Previous Command
ninja -C build
# Updated Command
meson compile -C build

4. Since Ninja is bundled with Meson 0.57.0, a separate section for its
installation may not be necessary. Is this correct?

Thanks!
