I tried for Xenomai OS but the message($$QMAKESPEC) is not printing at . Donno why ? and i am struck

Hi! What Qt version do you use on Xenomai? The problem might be because it can't find the compiler.

ManiRon

@Cobra91151 using 4.7 version QT in xenomai

So, for example you should check the directory: ...\Qt\4.7\mingw53_32\mkspecs

Here is what I get:

Xenomai is built with the Linux kernel, so you should try all the possible scope conditions for linux. Also, what compiler do you use on Xenomai? It will help to find it faster.

how to check the compiler sir?

Cobra91151

@ManiRon

You can check the compiler: Tools => Options => Kits => Compilers in the Qt Creator.

For example:

Are you sure you can build the empty project on Xenomai?

ManiRon

@Cobra91151

Will check and say sir

@ManiRon

OK. By the way, I have another solution to your problem but I can't check it because older Qt -> Q_WS* macros were dropped in favour of Q_OS*. So I will add both solutions for older and newer Qt versions.

You can add macros in the code to check the OS and load libs for example on Win OS:

Qt 5.x:

#ifdef Q_OS_WIN
#pragma comment(lib, "yourlibforwin")
#elif Q_OS_LINUX
#pragma comment(lib, "yourlibforlinux")
#else
#pragma comment(lib, "yourlibforxenomai")
#endif

Qt 4.x

#ifdef Q_WS_WIN
#pragma comment(lib, "yourlibforwin")
#else
#pragma comment(lib, "yourlibforlinux")
#endif

can i implement this in the .PRO file?

Cobra91151

@ManiRon

No, you can't have it in the .pro file. So what about the compiler? Have you built the empty project on Xenomai?

ManiRon

@Cobra91151

Not yet checked . Once i check it will inform u sir.
