Add IOKIT framework to *.pro file

[cristeab]

Hi

I am trying to use IOKIt framework in my macOS application developed with Qt5.9.1. I have added into the *.pro file this code

LIBS += -framework IOKit

but the compilation line does not contain any reference to this framework and IOKitLib.h file is not found. Can anyone tell me what I am doing wrong ?

thanks
Bogdan

Hi,

Did you re-run qmake after add the framework ?

How are you including the headers from the framework ?

Hi
Yes, I have rerun qmake. Following this link
http://doc.qt.io/qt-5/qmake-platform-notes.html#using-frameworks
no explicit path to IOKit framework header was added.

Also, at compile time I can see 2 other frameworks from macOS being used, but not IOKit. Below is the error I get:

What version of Xcode are you using ?

Can you show how you include IOKitLib.h ?
Can you show the complete .pro file for your project ?

Hi
I am using latest Xcode version from macOS Sierra. Unfortunately I cannot post the entire *.pro file. However, after specifying in INCLUDEPATH IOKitLib.h path it seems that I can get past the above error.

Are you using #include <IOKitLib.h> or #include <IOKit/IOKitLib.h> ?

[cristeab]

Just #include <IOKitLib.h>. The problem seems to solved, I just needed to add in INCLUDEPATH the path to the framework header and in LIBS "-framework IOKit"
