Bug with systeminfo

**bird12358** · 26th January 2014, 10:28

Hello,

I would like to know the remaining capacity of my computer battery. So I install the Mobility module named systeminfo.
I use it on ubuntu 12.04 (Qt 4.8.4). I compile the example given in the module.
On the battery part, all the informations is at 0 or -1. I thought I had to be as root to get the informations.
Unfortunatly this is not the cause of the problem.

Do I have to install an other module or a package on ubuntu to be able to get informations?

Best regard

I got this problem too on a debian testing.

I made it work by building my own version from the source.

This is how I understand this issue : according to .pro file of systemInfo all platforms except meego do not use upower for battery information but HAL or a proc/acpi deprecated entry...
But my computer doesn't use HAL which has been replaced by upower some time ago and does not have the proc/acpi entry for the battery.

So inside the source I changed the systeminfo.pro from

Qt Code:

Switch view

contains(CONFIG,meego): {
  SOURCES += linux/qdevicekitservice_linux.cpp
  HEADERS += linux/qdevicekitservice_linux_p.h
} else {
  DEFINES += QT_NO_UDISKS QT_NO_UPOWER
  !contains(QT_CONFIG,embedded):!contains(QT_CONFIG,qpa): LIBS += -lX11 -lXrandr
}

contains(CONFIG,meego): {
  SOURCES += linux/qdevicekitservice_linux.cpp
  HEADERS += linux/qdevicekitservice_linux_p.h
} else {
  DEFINES += QT_NO_UDISKS QT_NO_UPOWER
  !contains(QT_CONFIG,embedded):!contains(QT_CONFIG,qpa): LIBS += -lX11 -lXrandr
}

}

Rebuild and use it instead of the package lib, it works fine for me.

Thank you for the answer.
But in my systeminfo.pro file there is not that sentence:

DEFINES += QT_NO_UDISKS QT_NO_UPOWER

I can put you my systeminfo.pro file :

I tried different modifications but I still don't have battery informations.

**nix** · 26th January 2014, 17:23

Yes, your .pro has been fixed. Where did you get it? I download mine from https://qt.gitorious.org/qt-mobility...3cb1887d74614:

Did upower work fine on you computer?
Try :
upower -e , it gives me, 2 results : */line_power_AC0 and */battery_BAT0
upower -i with the complete line containing battery from the previous command, this should give you a lot of information about your battery.

If it works fine, I have no idea why systeminfo cannot read them. Maybe you can try the way i do, by compiling the library in debug mode and the example too and go step by step with gdb to find out where an error occurs.

So I would like to compile in debug mode, how can I compile the projet and the src in debug mode?

**nix** · 26th January 2014, 17:52

Another idea, are you sure you are really using the right library? Check the library you are using with ldd qsysinfo, it should point to the built lib and not the package one.

For debug mode, I open both .pro file with qtcreator and build in debug. I use LD_LIBRARY_PATH to force the example binary to use the right library.

It's just we use different sources and build option, the one in the .deb package can be different too.
But according to your ldd result yours is fine.
I suggest try with a debugger and see why you are skiping upower info. Does the code managing upower info is reached, does it return an error, etc...

I try to install systeminfo on an other computer but I still have the same problem. Do it come from my computers or from the systeminfo module?
