[HUANG]

dear guys:
I'm a college student and just start using palabos through code::blocks. When I Open the project file '$(PALABOS)/codeblocks/Palabos.cbp' under code::blocks, as the palabos' offical website says, and build the project, there are 4 errors appeared:

||=== Build: Release in Palabos (compiler: GNU GCC Compiler) ===|
C:\cygwin\home\HUANG\palabos-v1.5r1\src\core\plbTimer.cpp||In member function 'void plb::global::PlbTimer::start()':|

C:\cygwin\home\HUANG\palabos-v1.5r1\src\core\plbTimer.cpp|81|error: 'clock_gettime' was not declared in this scope|
||=== Build failed: 4 error(s), 0 warning(s) (0 minute(s), 2 second(s)) ===|

the corresponding codes of these four errors are the same:

clock_gettime(CLOCK_REALTIME, &ts);

Is there are some problem in offical codes? Or if it is possible that there is something wrong with my compilers? There are three compilers which can be detected by code::blocks,GNU GCC Compiler(minGW), GNU Fortran Compiler(minGW) and Cygwin GCC.
I'm not really good at these things. Can anyone help me to solve this problem? Thank you in anticipation of your assistance.
