[Pkg-dpdk-devel] 18.08 build failure on ppc64el

[Christian Ehrhardt]

Being MLX code I'm setting Thomas on CC as well, maybe he knows already.

Recreating a test case with sane headers - that is:

/*
*#include<linux/if_link.h>
*#include<linux/netlink.h>
*#include<linux/rtnetlink.h>
*#include<net/if.h>
*#include<rdma/rdma_netlink.h>
*#include<rte_errno.h>
*#include"mlx5.h"
*#include"mlx5_utils.h"
*/

#include <stdbool.h>
#include <stdint.h>
#include <stdio.h>

Eventually results in:
# 25 "test.c" 3 4
 _Bool
# 25 "test.c"
      port_name_set =


But the error is listing that as type "‘__vector __bool int"

I wonder if any of the more crazy headers redefines bool?!

Enabled these on top, still the same
#include <linux/if_link.h>
#include <linux/netlink.h>
#include <linux/rtnetlink.h>
#include <net/if.h>
#include <rdma/rdma_netlink.h>

Finally pulled in the MLX/RTE things

MLX from the 18.08 package and headers from 17.11.3 is too much of a
Frankenbuild suffering too much.
I'll need the real thing building locally on ppc64el ...


I see it defined as:
 __attribute__((altivec(bool__))) unsigned port_name_set =

after
cd ./debian/build/static-root/build/drivers/net/mlx5/
gcc -Wp,-MD,./.mlx5_nl.o.d.tmp -Wdate-time -D_FORTIFY_SOURCE=2 -m64
-pthread   -DRTE_MACHINE_CPUFLAG_PPC64 -DRTE_MAC

mlx5_nl.o -c /home/ubuntu/deb_dpdk/drivers/net/mlx5/mlx5_nl.c

Which could be the source of the mismatch.

More after lunch ...


P.S. Yes I know I'm supposed to tag 18.05.1-RC , just not getting to it yet
:-/
