Hi Bruce,

May I know the correct way of 32bit compilation on 64bit X86 machine. I tried the "-m32" c_args, but it returns the below error:

b10814 at dpdk-xeon:~/dpdk-up$ meson build -Dc_args='-m32'
Directory already configured.

Just run your build command (e.g. ninja) and Meson will regenerate as necessary.
If ninja fails, run "ninja reconfigure" or "meson --reconfigure"
to force Meson to regenerate.

If build failures persist, run "meson setup --wipe" to rebuild from scratch
using the same options as passed when configuring the build.
To change option values, run "meson configure" instead.
