Problems building "Hello world"

Fully motivated I want to join the club of developers, and start programming applications for the N900. But somehow I'm already stuck with the "hello world" example. :(

Maybe first what I've done so far:

1. Tried the maemo SDK virtual image on my windows machine, followed the instructions and code on the forum.nokia.com website (http://www.forum.nokia.com/info/sw.n...h_Maemo_5.html)

Somehow I wasn't able to build the application in this VM, so I decided to set up a laptop with Ubuntu and all the development tools

2. Installed Ubuntu, scratchbox, maemo SDK and ESBox following this guide:
http://wiki.maemo.org/Documentation/...l_Installation

3. Followed the example again, and ended up at the same point. Following is the error message I get (in VM and the Ubuntu machine):

Code:

configure: error: Package requirements (hildonmm libosso) were not met:

No package 'hildonmm' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix.

Alternatively, you may set the environment variables HELLOWORLD_CFLAGS and HELLOWORLD_LIBS to avoid the need to call pkg-config.

See the pkg-config man page for more details.

*** exited with code 1

I was told (http://talk.maemo.org/showthread.php?t=36987&page=4) that the missing libraries should be in the scratchbox environment, but how can I check if they are already there or not? As this happened to me in VM as well, could there be anything wrong with the code in the example? :(

Hope that somebody can help me...

Stupid guess - but did you try this? http://forums.internettablettalk.com...d.php?p=339617

Re: Problems building "Hello world"

Tried it, but I get the following error message:

Code:

Reading package lists... Done

Building dependency tree... Done

E: Couldn't find package libhildonmm-dev

So I think this might no longer be up to date (?).
Again I tried it with and without scratchbox.

Pants....
I'm heading home to try it all now - so catch up with you soon! :)

Re: Problems building "Hello world"

Well, the "hello world" example that you're trying to build is the C++ one.

The C++ bindings for Gtk+/Hildon are supported by the community (by the Openismus guys), so the hildonmm packages are in the Extras repositories (not installed in the default installation)

Add this line to the /etc/apt/sources.list in scratchbox:
deb http://repository.maemo.org/extras-devel fremantle free non-free

And then, apt-get update, and apt-get install libhildonmm-dev

If you want the default examples (in plain C) are here: https://garage.maemo.org/svn/maemoexamples/trunk/

I know that the one in Forum Nokia is the C++ one, it's a bit confusing because the Hildonmm/Gtkmm isn't supported officially.

Might want to tack a "fakeroot" to the start of those two commands. E.g.:

fakeroot apt-get update
fakeroot apt-get install libhildonmm-dev

Re: Problems building "Hello world"

I logged myself in to scratchbox and did the commands for each of my targets and now it works! :)

@lardman: is logging in to scratchbox equal to using fakeroot in the 'regular' terminal? I'm still a little confused with these scratchbox / fakeroot / target things...

Lol was going to ask what fakeroot does, but i think common sense may have got the better of me :)

fakeroot runs a command in an environment were it appears to have root privileges? Therefore removing the need to do everything in root? - just a guess :)

Bingo. Aside from not having to have a root password to execute a command (thus making fakeroot potentially dangerous), it ensures that after the command is executed, you are then executing commands as a normal user.
