How to add macro for the LIBS in the .PRO file

@Cobra91151

for xenomai what should i do sir?

While giving unix it runs the library for linux and if i want to do the same for xenomai what should i specify?

And i want to know where this message($$QMAKESPEC) will be displayed?

[Cobra91151]

@ManiRon

Xenomai should have something, I use Windows OS, so I don't know exactly. message($$QMAKESPEC) will be displayed in the General Messages in the Qt Creator. Check the output message($$QMAKESPEC) and reply. I will try to help you.

[ManiRon]

@Cobra91151 Ok sir

@ManiRon
I tried with windows it returned win32-g++ ?

Ok. So you can use it on Windows, but you have to check it with Xenomai. By the way, win32-g++ means that you use MinGW compiler. Reply when you get the output for Xenomai.

@Cobra91151 ok Sir

[ManiRon]

@Cobra91151

I have a doubt?

[ManiRon]

@Cobra91151

i generated a code in .pro file as

win32-g++{
LIBS += path
}
linux-g++ {
LIBS += path
}

i am creating a bundle with the .exe and the required files and if i run this in a PC which does not have QT will it work

You have doubt about what? Is linux-g++ scope condition from Xenomai output?

Also, you have to provide all the necessary Qt libs if the Qt is not static (on the PC which does not have Qt) otherwise it wont work. For example, for Windows, you have to run windeployqt.exe to get Qt shared libs.

Official docs about the deployment for Windows: http://doc.qt.io/qt-5/windows-deployment.html

@ManiRon

So, you should have something like this in the pro file:

TARGET = TestApp #Your executable filename without the extension

win32-g++ {
    LIBS += path
    QMAKE_POST_LINK = $$(QTDIR)/bin/windeployqt.exe $$shell_quote($$DESTDIR/$$shell_quote($$TARGET).exe) --no-compiler-runtime
}

This will add one more build step to the project, but it will help to deploy all the necessary Qt libs. By the way, it will work only for Windows deployment and shared libs Qt version.

Linux deployment Qt docs here: http://doc.qt.io/qt-5/linux-deployment.html

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

[Cobra91151]

@ManiRon

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.

[ManiRon]

@Cobra91151

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

[Cobra91151]

@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

Docs: http://doc.qt.io/qt-5/qtglobal.html

Qt 4.x

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

Docs: http://doc.qt.io/archives/qt-4.8/qtglobal.html

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?
