I've just installed a new system - Ubuntu 11.10 beta x64 and can't get dmd/phobos 2.055 to work.
When I try to compile file hello.d with the following content: import std.stdio; void main() { writeln("Hello World!"); } I get this error: /usr/lib/gcc/x86_64-linux- gnu/4.6.1/../../../../lib/libphobos2.a(datetime_48b_1ec.o): In function `_D3std8datetime5Clock11currStdTimeFNdNeZl': std/datetime.d:(.text._D3std8datetime5Clock11currStdTimeFNdNeZl+0x1d): undefined reference to `clock_gettime' /usr/lib/gcc/x86_64-linux- gnu/4.6.1/../../../../lib/libphobos2.a(time_c0_4d1.o): In function `_D4core4time12TickDuration12_staticCtor7OFNeZv': src/core/time.d:(.text._D4core4time12TickDuration12_staticCtor7OFNeZv+0x1f): undefined reference to `clock_getres' /usr/lib/gcc/x86_64-linux- gnu/4.6.1/../../../../lib/libphobos2.a(time_c0_4d1.o): In function `_D4core4time12TickDuration14currSystemTickFNdNeZS4core4time12TickDuration': src/core/time.d: (.text._D4core4time12TickDuration14currSystemTickFNdNeZS4core4time12TickDuration+0x1f): undefined reference to `clock_gettime' collect2: ld returned 1 exit status --- errorlevel 1 Nothing else using Phobos compiles either. I've seen previous related threads. Tried -L-lrt, didn't work. I tried the .deb package for Ubuntu, the binaries shipped in the source archive, as well as compiling Phobos myself (removing DMD/Phobos every time to make sure no files persisted), but nothing helped. Has anyone encountered this problem? Did anyone get it to work on Ubuntu (especially 11.10)?
