View Full Version : First time indicator applet - help needed

April 5th, 2011, 05:39 PM

I'm just trying to get started on an indicator applet and I found an article and example in the Gnome Journal (http://gnomejournal.org/article/67/an-introduction-to-the-message-indicator). I'm just trying to compile it but am getting a bit stuck (a new to C).

Here's what I'm getting when I compile:

$ gcc indicator.c -o indicator $(pkg-config glib-2.0 indicate --libs --cflags)
indicator.c:4:43: error: libindicate/indicator-message.h: No such file or directory
indicator.c: In function ‘main’:
indicator.c:38: error: ‘IndicateIndicatorMessage’ undeclared (first use in this function)
indicator.c:38: error: (Each undeclared identifier is reported only once
indicator.c:38: error: for each function it appears in.)
indicator.c:38: error: ‘indicator’ undeclared (first use in this function)

I've installed libglib2.0-dev and libindicate-dev.

I'm assuming either the code has changed from the example or I'm missing some of the required header packages.

I've attached the code if anyone's interested.

Yup, it looks like the code you have is written using an older version of the library. Check out the examples in the libindicator source tree either here (http://bazaar.launchpad.net/~indicator-applet-developers/libindicate/trunk/files/head:/examples/) or via

apt-get source libindicator

hope this helps!

Thanks Johnl. You're a genius. Still can't compile the new example but getting closer.

Most probably pkg-config doesn't know a package named 'indicate'

What does this output(on the left column)?

pkg-config --list-all | grep indicate

If it outputs only one result then use it instead of 'indicate' in your compilation command. If it is more please post the results or try them one by one.
