Subject: [dpdk-dev] 16.07-rc2 issue with rte_rtm_init(void) constructor
Date: Wed, 13 Jul 2016 22:58:09 +0000	[thread overview]
Message-ID: <C9B4A9F8-E6CB-4B5A-9472-6E2C4877C158@cisco.com> (raw)


Folks,

I have issues with linking application to 16.07-rc2.

Looks like reason is constructor function in include file,
so our unit test apps are failing to link as they are not linked with dpdk libs.
(and they should not be as they are not calling any dpdk function).


static inline void __attribute__((constructor))
rte_rtm_init(void)
{
        rtm_supported = rte_cpu_get_flag_enabled(RTE_CPUFLAG_RTM);
}

linking fails with:
dpdk/include/rte_spinlock.h:103: undefined reference to `rte_cpu_get_flag_enabled’

Is there any chance that this one is moved to some .c file, so it is loaded
only when it is really needed?

Thanks,

Damjan
