Problem deploying project on N950 using MADDE

[tube42]

I am trying to get a terminal flow working so I can ditch QtCreator for the trusty emacs+terminal "IDE". I am currently stuck on the last (?) task: installing the uploaded .deb on the device. I have followed this guide to get there:

http://library.developer.nokia.com/i...uide_5fb9.html

I am basically running these commands after setting up keys and testing the connection to my N950:

# create project template
mad pscreate -t qt-simple myapp

# build
cd myapp
qmake
make
mad dpkg-buildpackage

# install it:
mad remote -r N950  send ../myapp_0.1_armel.deb
mad remote -r N950  install myapp_0.1_armel.deb
#

The last line fails with this error:

devrootsh: '/bin/sh': command not known -- executing with user permissions
dpkg: requested operation requires superuser privilege
aegis-installing myapp (from '')
ssh: exit 2

Since the package is already on the devices, I tried to install it manually:

$ mad remote -r N950 shell

BusyBox v1.19.0.git (Maemo 3:1.19-7+0m6) built-in shell (ash)
Enter 'help' for a list of built-in commands.

/home/developer $ dpkg -i madde/myapp_0.1_armel.deb
dpkg: requested operation requires superuser privilege
aegis-installing myapp (from '')

Does anyone know why this is happening? I am using the latest SDK on windows and can actually deploy other projects from QtCreator without any problems.

You can install package on the device using scp and ssh:

#!/bin/bash
NAME=package
DEVICE=192.168.2.15
ssh ${DEVICE} rm -rf "/home/user/MyDocs/${NAME}*.deb"
scp ${NAME}*.deb ${DEVICE}:/home/user/MyDocs/
ssh ${DEVICE} dpkg -i "/home/user/MyDocs/${NAME}*.deb"

Thanks divanov,

But if you look at my first post, you will see that this is what I finally did (although I used "mad remote shell" instead of direct ssh). It did not work (no error shown but no package was installed)

The preferred method for doing all this is of course "mad remote install", and I would like to get it working. Does anyone know what the problem is? Can anyone less re-produce this?

I looked and this is completely different from what you've done.

See, I use ssh hundred times per day and always successfully.

SSH is highly stable tool used by barely everyone and MADDE is unstable strange utility with few users. There must be really good reason to use the latter.

And dpkg indeed requires root privileges, while you were logged as "developer" - another quirk of MADDE.

great, thanks for clearing this up.

There are three reasons for using madde: (a) it's the "official way" for creating and deploying packages and (b) it is supposed to fully support Harmattan & N950 and (c) it is automated.

And dpkg indeed requires root privileges, while you were logged as "developer" - another quirk of MADDE.

Ok, I was missing the root part.

Question to Nokia: Why cant the "developer" account install packages on N950?? And why is this not mentioned anywhere in the documentation?

If you want official way, use Qt Creator and no problem then.

Because MADDE runs applications as "developer". Running application as "root" may cause serious harm to the device and is irrelevant for testing as users run all applications as "user".

I've just noted that you are using Windows as a host system...

You can get root permission on the device with a command
sudo gainroot
or alternatively using ssh:
ssh root@localhost

ok, back on topic:

I managed to get "mad remote install" working by clearing the device (which was a fresh developer kit, so something had gone very wrong there). There are however a number of other problems with madde on N950 that I hope Nokia fixes before N9 hits the stores.

There is no "sudo" on N950, you can however run "devel-su" to get a root shell or you can ssh directly as root (i.e. ssh root@<you N950 IP>). The root password is "rootme".

A third alternative that can be used for installing a package while logged in as developer, is "/usr/lib/mad-developer/devrootsh dpkg -i foo.deb".
