"error: 'clock_gettime' was not declared in this scope" and "error: 'CLOCK_MONOTONIC"

Usung qt 4.8.1 unde windows. compiling "pure" c++ code i get the following errors:


trigwiz.h:149: error: 'CLOCK_MONOTONIC' was not declared in this scope
trigwiz.h:149: error: 'clock_gettime' was not declared in this scope

I know clock_gettime is in rt library and so i modified the .pro file as following:


TEMPLATE = app
CONFIG += console
CONFIG -= qt

SOURCES += main.cpp \
trigwiz.cpp

HEADERS += \
trigwiz.h

LIBS += -lpthread -lrt

unfortunately it was unsuccessfull...

you have a compiler error. so address the c++ compiler error. This has nothing to do with Qt.

It has to do with the windows qt environment and the way it spread the file in the filesystem....
How can I check wether the lib is correctly reachable (presence/lib path) by the linker?
Moreover the time.h include should contain the CLOCK_MONOTONIC define. Where can I find it ?

Qt environment doesn't spread any files anywhere.

You can compile a program that uses it. If it fails, then it is not reachable.

time.h? Probably in the place where you had put it. I don't see what Qt has to do with it. You're not even using Qt anywhere:
CONFIG -= qt
