How to include glib-object.h

Hi,

I try to port a Maemo 4.1 pygtk application to Qt4 on Maemo 5. The application
is running, but now it requires location data. Since the location API has
changed in Maemo 5, I try to understand the example given at
http://bit.ly/a3HTFD

As soon as I put
#include <location/location-gps-device.h>
#include <location/location-gpsd-control.h>
in one of my files, the compiler complains:
http://pastebin.com/c45NU0FB

glib-object.h: No such file or directory

This file includes further files, as listed here:
http://bit.ly/dprcX6

I'm obviously missing some include path or similar. Appearently I'm a bloody
hobbyist, so please bear with me :) . Any hint, even RTFM is much appreciated.

Best regards,

ce

Try adding -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include to your
gcc invocation.

Actually you should include `pkg-config --cflags glib-2.0`

May be better solution is to use directly qt-mobility libqtm-location .
Qt mobility will be foture proof cross platfrom solution. For marmatan
native location API will anyhow change. For fremantle libqtmlocation
is wrapper over liblocation0 . For Harmatan its is direct connection to dbus
but API remains same.

Well, actually, the location library apparently provides a pkg-config
file that he should check for instead, so he doesn't have to worry about
checking for its glib dependency.

However, this example suggests that the liblocation pkg-config file is
broken, because it suggests checking for glib too. Well, that whole
pkg-config call is very strange.

CCing David so he can investigate.

I fixed the pkg-config invocation to be less misleading:

pkg-config --cflags --libs liblocation

and as the liblocation pkg-config file correctly depends on glib-2.0,
that is included automatically in the compiler and linker flags.

I just added
CONFIG += link_pkgconfig
PKGCONFIG += libnotify
to the .pro file as suggested here:
http://bit.ly/6nsy79

This does the trick, though I obviously have not understood the issue
completely :) .

Thanks for the help,
