Duo basic tutorial

[abickerton]

I'm looking to start compiling addons for my Duo. I'm familiar with C & C++, but I'm a Java guy by day so be gentle 🙂
The snag is that there seems to be no tutorials regarding building an opensource app so that it can be used on a Duo.

What are the pitfalls to expect. I've read that an dist-upgrade is a very bad idea, does anyone know why?

- What is not available for tinkering to updating due to being closed source
- using the pre built dev environment posted in the forum...
-- If I were to checkout a git / svn snapshot, what do I need to know before I can build a .bin that will work on the duo?

Is there a more recent repository for the Sparc Duo?

I'm afraid to tell you that java will not work on a sparc. The machine is to slow to work with java applications. Maybe you can use optimized or lite java framework that will work on small java applications.

The snag is that there seems to be no tutorials regarding building an opensource app so that it can be used on a Duo.

You have to keep in mind that the duov1 is running a sparc cpu so you have to add the following parameter to your config --build=sparc-linux or maybe --host=sparc-linux

I think the main problem is, that if you do a dist-upgrade the configurations files will be changed which will break the frontview. Also a dist-upgrade will remove the ssh service when you try to fix the broken packages with apt-get -f. I'm not sure whether this problem exists or not, because my last try to do a dist-upgrade is too long ago.

If you mean how you can create a .bin for your addon look here http://www.readynas.com/?p=346

If you update libc6 it will break Frontview.

What does break the frontview exactly? If you upgrade all libaries which run with the new libc (for example apache, perl libaries) it should work?

[mdgm-ntgr]

There are perl scripts that would be broken by a perl upgrade too, I think. Best not to experiment on a production system

[abickerton]

It's been a while since I was here. Perhaps, it'd be a good idea to document exactly what breaks so that we can at least fix the dis upgrade problem.

I would recommend the following stuff to fix the debian installation:

apt-get update
#fix perl installation (some files are missing)
apt-get install --reinstall perl
#will fix an error when using checkinstall
apt-get install less
ln -s /usr/bin/less /usr/bin/sensible-pager
#update-alternatives --config pager
apt-get install nano
#http://www.shellperson.net/change-sensible-editor/ update-alternatives --config editor
#install service
apt-get install sysvconfig
#execute long operations in a screen mode
apt-get install screen
#create debian packages
apt-get install checkinstall
apt-get install equivs
apt-get install gettext
#mysql stuff
apt-get install libmysqlclient15-dev

Does anybody else know some helpfull stuff for the readynas duov1?

[EDIT]
You can also create a symlink for /etc/apache/httpd.conf -> /etc/frontview/apache/httpd.conf
