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.
