I can't seem to use std.datetime at all. I get undefined reference on whether I use a StopWatch, or if I just try to compile the unittest. All I have to do is declare a StopWatch:
import std.stdio; import std.datetime; void main() { StopWatch sw; } This fails to compile: [kai@worky ~]$ dmd datetime_test.d /usr/lib/gcc/x86_64-redhat-linux/4.5.1/../../../../lib/libphobos2.a(datetime_35c_30e.o): In function `_D3std8datetime7systimeFNeZS3std8datetime5Ticks': std/datetime.d:(.text._D3std8datetime7systimeFNeZS3std8datetime5Ticks+0x1c): undefined reference to `clock_gettime' /usr/lib/gcc/x86_64-redhat-linux/4.5.1/../../../../lib/libphobos2.a(datetime_359_1fe.o): In function `_D3std8datetime5Ticks12_staticCtor5OFNeZv': std/datetime.d:(.text._D3std8datetime5Ticks12_staticCtor5OFNeZv+0x1b): undefined reference to `clock_getres' collect2: ld returned 1 exit status --- errorlevel 1 Am I missing some libraries somewhere? If I 'import core.sys.posix.time, core.sys.posix.sys.time;', parts of dattime work, and others don't. A main with just: writef("%s %s\n", (is(typeof({auto fp = &clock_gettime; })))); Prints "true true", but using them like this gives undefined again: timespec ts; writef("%d\n", clock_getres(CLOCK_REALTIME, &ts)); datetime_test.o: In function `_Dmain': datetime_test.d:(.text._Dmain+0x34): undefined reference to `clock_getres' collect2: ld returned 1 exit status --- errorlevel 1 I'm running Fedora 14 x86_64, dmd-2.051-0.i386, glibc-2.13-1.i686. Any ideas?
