[dpdk-dev] [PATCH v1 0/2] eal: fix symbol missing in version map

[Cunming Liang]

These two patches are the fixing for the compling error when CONFIG_RTE_BUILD_SHARED_LIB=y.
The root cause is *per_lcore__socket_id* and *rte_sys_gettid* are missing in the version map.
Thanks for the notification from Tetsuya Mukawa <mukawa@igel.co.jp>.

[dpdk-dev] [PATCH v1 1/2] eal/linux: fix symbol missing in version map

[Cunming Liang]

As per_lcore__socket_id and rte_sys_gettid are missing in version map,
it causes compiling error when CONFIG_RTE_BUILD_SHARED_LIB is enabled.

Hi Liang,

I've confirmed it works on my Linux environment.

Thanks,

Please use Reported-by: in such case.

Fixes: ef76436c6834 ("eal: get unique thread id")
Fixes: 9e29251b2afa ("eal: thread affinity API")

NAK

This is the wrong way to fix this problem. Exporting global variables is
never a good solution when it can be helped.  Instead, rte_socket id should be
made a non inline function and exported.  Then the definition of
per_lcore_socket_id can be made private, protecting it from type changes.

Neil, I applied the patches to fix compilation on HEAD.
In case your comment makes sense, a cleanup would be appreciated.

Thanks
