Compiling DPDK 17.02 with a Busybox-based tar

Compiling DPDK 17.02 with a Busybox-based tar

[Raphael Cohn]

Hi,

To compile DPDK on a system with Busybox tar installed, it's necessary to
make a small change to the build system:-

    sed -i -e '/--keep-newer-files/d' mk/rte.sdkinstall.mk
    sed -i -e 's;--strip-components=1 \\;--strip-components=1;g' mk/
rte.sdkinstall.mk

I'm not sure whether the impact of this change fundamentally affects DPDK.
I'm a little surprised that tar is needed at all for a compile + install,
but I haven't investigated further. Is it being used to do a copy?

Raph

Yes it is used to make a copy.
It is a convenient one-liner.

I am a bit surprised that you need to install DPDK with busybox.
The busybox systems are generally cross-built and prepared out of the box,
with the host tools.
However, if you feel it is important to install DPDK on such target,
you are welcome to propose a patch.

Why it is surprising that I need to compile DPDK on a system Busybox?

I currently build DPDK both for my local Alpine Linux system (busybox)
using the system compiler, use busybox for my cross-tools toolchain, and
also use it in Libertine Linux. It means a system using DPDK can be much
more minimal. Likewise, Aboriginal Linux uses Busybox (and, shortly,
Toybox), for similar reasons. It also means users of my rust crate can work
in a wider range of systems than RHEL / Ubuntu.

I understand the need for busybox on the target system.
I was just saying that generally we use a more complete system on the
host building a target. But you are free to use any tool you want :)
