[dpdk-dev] [PATCH] mk: fix link with glibc < 2.17

[Thomas Monjalon]

2016-07-25 12:57, Thomas Monjalon:
> There is a dependency on librt with old glibc.
> The -lrt option was added everywhere it is needed but was also
> added in some applications makefiles as the first link option.
> The problem is this option is really useful only if added after
> the objects or libraries using it (except if using --whole-archive).
> And the -lrt options put after were removed to avoid duplicates.
> 
> It was resulting in errors linking test application:
> eal_timer.c:(.text+0x128): undefined reference to `clock_gettime'
> eal_timer.c:(.text+0x166): undefined reference to `clock_gettime'
> eal_alarm.c:(.text+0xda): undefined reference to `clock_gettime'
> eal_alarm.c:(.text+0x211): undefined reference to `clock_gettime'
> 
> It is fixed by removing superflous -lrt in app makefiles.
> 
> Fixes: 281948b4753e ("mk: fix missing librt dependencies")
> Fixes: 2f6414f4baf1 ("mk: fix static link with glibc < 2.17")
