Subject: [dpdk-dev] [PATCH v9 1/2] timer: move from common to Unix directory
Date: Wed, 17 Jun 2020 12:39:14 +0300
Message-ID: <20200617093915.16428-2-fady@mellanox.com> (raw)
In-Reply-To: <20200617093915.16428-1-fady@mellanox.com>

Eal common timer doesn't compile under Windows.

Compilation log:
error LNK2019:
unresolved external symbol nanosleep referenced in function
rte_delay_us_sleep
error LNK2019:
unresolved external symbol get_tsc_freq referenced in function set_tsc_freq
error LNK2019:
unresolved external symbol sleep referenced in function set_tsc_freq

The reason was that some functions called POSIX functions.
The solution was to move POSIX dependent functions from common to Unix.
