Subject: [dpdk-users] Compiling 32-bit dpdk with meson in 64-bit container
Date: Tue, 13 Oct 2020 15:54:13 +0000	[thread overview]
Message-ID: <MRXP264MB01207ABAEC5C18FC73B14D5192040@MRXP264MB0120.FRAP264.PROD.OUTLOOK.COM> (raw)

Hi all, hi Bruce,

I have an issue to compile 32 bit dpdk (version 20.08) with meson in a 64-bit container.
As I can see from meson.build, it deducts the arch from the cc sizeof:

dpdk_conf.set('RTE_ARCH_64', cc.sizeof('void *') == 8)

The attempts to workaround it and set RTE_ARCH_64 to false gives good values in build/rte_build_config.h:

#define RTE_ARCH i686
#undef RTE_ARCH_64
#define RTE_ARCH_I686 1
#define RTE_ARCH_X86 1
#define RTE_CACHE_LINE_SIZE 64

but, nevertheless, dpdk is compiled for 64 bit and not for 32 bit.

Before, with make build system, RTE_ARCH_ values defined arch and compilation flags for x86 (like -m32 for i686), but with meson it seems to be more complicated?
Is there a way to compile 32 bit dpdk (version 20.08) with meson in a 64-bit environment?

Kind regards,
Renata
