[songww]

For iOS, should add flag -miphoneos-version-min=9.0 to cc.

[songww]

Many srcs not compiled for mobile default. Perhaps we should add some feature gates to works for mobile?

[simlay]

To fix this thread_local issue, specify a IPHONEOS_DEPLOYMENT_TARGET of something 9.0 or later. It defaults to 7.0.

Any news so far ?
