This shows it is not missing any dependencies. So how do you think your application should know to find and load it from /home/pi/qhttp/xbin?

I have

LIBS += -L/home/pi/qhttp/xbin -lqhttp

in pro file

Sorry, Why do you want use this library? I checked source code, httpclient does not use Qnetworkmanager but, it sends directly with QTcpSocket.

Thanks

I'm not tied to the lib. any lib I can include in my project without having a heart attack will go. do you have one to suggest?

LIBS += -L/home/pi/qhttp/xbin -lqhttp

This tells the linker where to locate the libqhttp.a file while linking. I am not sure that it puts anything into the executable to tell it to look in that directory for the libqhttp.so file at runtime. See @jsulm's last post earlier on above.

There is no libqhttp.so in Debug folder. I don't know how it's linked in run time.

well...no luck with the lib. do we have something more user friendly?

I told you to copy it into your build folder - why don't you simply try that?

I tried it of course. never ignore your suggestions :)

@jenya7 OK, then change to your build folder and execute

ldd YOUR_EXECUTABLE_FILE_NAME

What is the output?

@jenya7 I'm confused now: according to this output your app does not link to libqhttp.so.

in the build folder only a shortcut to libqhttp.so available. that's the reason I suppose.

jsulm

@jenya7 No, ldd should show all libraries your app is linking.

Well...I did Clean and then Build and now it seems like working at run time. at least server.listen method gives no exception. thank you.

jsulm

@jenya7 Yes, clean rebuild often does wonders just like Windows reboot :-)
