eal_memory.c:56:18: fatal error: numa.h: No such file or directory

Question

When I execute make from the quick start instruction for DPDK, I get the following error:

eal_memory.c:56:18: fatal error: numa.h: No such file or directory

The error comes out even when libnuma is installed already:

>sudo yum install numactl-libs.x86_64
Loaded plugins: fastestmirror, langpacks
Loading mirror speeds from cached hostfile
 * elrepo: mirrors.tuna.tsinghua.edu.cn
Package numactl-libs-2.0.9-6.el7_2.x86_64 already installed and latest version
Nothing to do

I'm using CenOS Linux release 7.3.1611 (Core).

How do I fix this problem?

Answer 1

Try to install numactl-devel:

sudo yum install numactl-devel

Easing

When I try this, I get No package libnuma-devel available. Would you know what to do? – Serviceman

@kurt Well, it could be named numactl-devel or similarly. Anyway, you need development package, it comes with the missing headers... – Easing

i tried sudo yum install numactl-devel.x86_64 for 64-bit machine, and it works. thank you so much for your help. – Serviceman

Answer 2

numa.h is also part of libnuma package.

Please install libnuma package:

CentOS 6.9: yum install libnuma-devel

Ubuntu: apt-get install libnuma-dev

Looks like on CentOS 7 docker container libnuma-devel is not available. In that case try yum install numactl-devel

Anticlockwise

on Centos:7 docker container yum install libnuma-devel not found, numactl-devel is found – Cankerous
