I don't use tomboy and it is not in our repositories. From the webpage I see it seems to use gtkhtml which is wrapped by a gtk-sharp assembly. The wrapper is hardcoded to the minor version of gtkhtml library and the configure script is not very "flexible" on it. How could the developer has not been aware of this issue ?!?

Anyway, for this very reason gtk-sharp has be updated recently and is as 1.0.8 in the repos. Please double check and report, though i prolly won't investigate further on apps which are not in the repos. There are reasons why they are not :)

I have gtk# 1.0.8, but it still doesn't work... I even recompiled Tomboy with the same result: it loads as "mono --debug tomboy" and it seems to be loaded according to "top", but its icon does not appear in the notification area. Not sure what's up with that, it stopped working with the upgrade to mono 1.1.4. I filed this here because I am not sure whose bug it is.

Hm, mono-1.1.4 is in testing, and meanwhile I saw some real quirks with it. Monodevelop eg., still works though it won't compile anymore.

I will leave that to the mono people to fix it.

... and mono-1.1.4 stays in testing, which is a pity, I like it actually.

erm, sorry, I really meant mono 1.0.6. I don't use Testing, I only use Current and Extra.

does tomboy run for you with mono 1.0.6?

I dunno, I never tried it. But you are saying you have running 1.0.6 or 1.1.4.
Tomboy runs with 1.0.6. This a testing system, with a manually rolled back mono 1.0.6. I also tried with 1.1.4, it's running, but wont compile I guess. I have no plain extra/current at finger tipps, but think it will indeed work on it.

I blame your installation, sorry

As I said, I meant mono 1.0.6 (I don't run mono 1.1.4, I use only Current and Extra, not Testing). Tomboy WAS able to run on this machine until a few weeks back. Sudenly, it stopped working, and a recompilation didn't fix it.

It works for me as you see on the screenie, with either mono-1.0.6 and 1.1.4

I know I am not crazy...
I just tried Tomboy on my other laptop, same effect: Tomboy loads, but no icon shows up on the notification area. Therefore, I can't use it, because it's not visible.

I checked on another box ... and guess what, it works :)
Ok, it's not for the repos, maybe some more mono-stuff comes in when things get more matured, since the move from 1.0.6 to 1.1.4 break too many apps.
But you got me on that interesting kind of thing bug.
What are you compiler switches? how did you compile it, etc. I need to know if you want help on it. And please check that:

Also the following observations:
running "tomboy"
on laptop "All done, ciao"
on bigbox (not much gnome stuff there): a novel of an error message basically saying: libpanel-applet-2.so.0 not found
but running "tomboy --tray-icon"
runs smoothely on either machine

did you invoke --tray-icon?

>What are you compiler switches?

./configure --prefix=/opt/gnome
make
make install

>on laptop "All done, ciao"

Yes, I have seen this.

>but running "tomboy --tray-icon"

Why do I have to run this now? I mean, in the past I just ran "tomboy" and it would automatically go to the notification area. How else one could insert a new note if tomboy is not visible?

... because behaviour changes in software at 0.x versions sometimes :)
maybe there are configuration files in ~/,gnome2 defining defaults.
Really, I have no clue, ask the tomboy boys about.
So does it means it runs for you, and this can be closed?

haven't tried it yet with the --tray-icon. Will do in a few hours.

ok, using the --tray-icon it works the *first time* I run it. Closing it down and restarting the same app gives me this:

eugenia@athlonxp:~> tomboy --tray-icon

I installed tomboy (I also have Mono installed) but when I launch it from the command line nothing happens. No error messages, etc. It just sits there regardless of whether I run it as root or normal user.

tomboy made it's way to AUR, which is a good place for it since the fast speed of it's an mono's development make occasionally breakages very likely. So far it is working quite nicely.
