[MinGW32] missing timespec_get() #830
Description
Trying to build for MinGW with the minimal features possible:
cmake -G "MinGW Makefiles" -DWITH_XML_BACKEND=0 -DWITH_SERIAL_BACKEND=0 -DWITH_USB_BACKEND=0 -DENABLE_IPV6=0 -DPYTHON_BINDINGS=0 -DWITH_NETWORK_BACKEND=0 ..
Yields:
F:\gv\dx-radio\libiio\tests\iio_common.c: In function 'get_time_us':
F:\gv\dx-radio\libiio\tests\iio_common.c:455:2: warning: implicit declaration of function 'timespec_get'
[-Wimplicit-function-declaration]
455 | timespec_get(&tp, TIME_UTC);
| ^~~~~~~~~~~~
F:\gv\dx-radio\libiio\tests\iio_common.c:455:20: error: 'TIME_UTC' undeclared (first use in this function)
455 | timespec_get(&tp, TIME_UTC);
| ^~~~~~~~
My MinGW (TDM / gcc version 10.3.0) do have an inlined clock_gettime() in it's <pthread_time.h>
(which gets included in <time.h> for _POSIX_C_SOURCE > 2).
But inlined only for __MINGW64__! So I tried this patch:
