Cannot build Pktgen on Ubuntu 24.04 LTS

[MathewColin]

Hello,

I installed DPDK 24.03 and I can run the sample testpmd app without any problems.
However, when I try to build Pktgen 24.07.0 I get the following error:

FAILED: lib/utils/libutils.a.p/_atoip.c.o

I am using gcc 13.2.0

Any advice on how can i solve this issue?

Thank you in advance!

Pktgen builds in my machine.
DPDK 24.07.0-rc1
Pktgen 24.07.0
GCC (Ubuntu 13.2.0-23ubuntu4) 13.2.0
Ubuntu 24.04 LTS

[dosarudaniel]

I have tried as well with the exact versions mentioned by you, I still have the same error..

What about your ninja and meson version?
We have:

$ meson -v
1.3.2
$ ninja --version
1.11.1

Attaching here the entire build output:

I have the same versions. I would not expect meson and ninja to cause a compile error.

Same compile error Debian 12 on gcc 12.2.0. switching to gcc 11.30 resolved and was able to compile and use pktgen.

[KeithWiles]

Interesting I am using GCC 13.2.0 and it works, not sure why 12.12.0 is not working and 11.30 is working. :-(

[mp1-bvd]

was also able to work around this problem on default debian gcc-12 by lowering the default optimization level from 3 to 2 via 'meson setup builddir -Doptimization=2'
