Re: [Paparazzi-devel] Installing paparazzi 4.2 on Ubuntu 12.04

OK, now it worked!

In case anybody else is interested, here is the course of action:
In ivy-ocaml dir:
(optional) sudo make uninstall (to have a clean start)
sudo apt-get install tk-dev
sudo apt-get install dh-ocaml
make COMPAT_SYMLINK_CREATE=y deb

Go to the directory with generated deb package (typically cd .. will do):
sudo dpkg -i ivy-ocaml_1.3.1_amd64.deb

That will install the package.

Then make sure your sw/logalizer/Makefile has the prce flag (https://github.com/podhrmic/paparazzi/commit/f28ccb53d053820dcdca5e437f05887d1f47545f)

Works with 4.2 version.

And yes, the symlinks are annoying:)

Thanks!

Hi Michal,

it might have been easier to build a debian package with the symlinks...
In any case, if you would have installed tk-dev, you wouldn't have had to change the makefile...

Also you can simply pass the arg to enable symlinks during install:
make COMPAT_SYMLINK_CREATE=y install

Regarding pcre, you proably need to add some pcre flags, something like
$(shell pcre-config --libs)
See https://github.com/paparazzi/paparazzi/blob/master/sw/logalizer/Makefile#L105

Cheers, Felix

HI Felix,

so I did this:
1. install tklib from Ubuntu Software center
2. sudo apt-get install tcl-dev
3. in ivy-ocaml do "make all" and then "make install" to install libraries
4. Change line 10 to "COMPAT_SYMLINK_CREATE ?= y" https://github.com/flixr/ivy-ocaml/blob/master/Makefile#L10
5. Change line 59 to "TKINC=-I/usr/include/tcl8.5" https://github.com/flixr/ivy-ocaml/blob/master/Makefile#L59 (that is the only place that has tk.h"
6. in paparazzi directory: make clean; make
7. here is the output:

[1]+  Done   

I can run the Pprzi centre, but not all files are generated (like messages.h) so it doesn't compile any airfarme.

Any ideas what should I do?

Thanks
M

You need to smylink them from the ivy and glibivy dirs into the main ocaml directory, see https://github.com/flixr/ivy-ocaml/blob/master/Makefile#L125

Hi Felix,

I am happy to do that by hand - where do I need to put the symlinks?

The only reason for using v4.2. is that it has been proven with hundreds of flight hours so our field group can rely on it (yet they still need some minor updates). But we are moving to Lisa MX board with (hopefully) 5.6. version soon:)

Thanks
M

Hi Michal,

I really don't want to re-enable the symlink, as it results in stupid warning for everyone using v5.0 and later.
And I definitely don't want to encourage or recommend using v4.x versions anymore ;-)

You can always set the symlinks by hand if you want or build the package with symlinks enabled yourself.

Cheers,
Felix

P.S. I can't keep wondering why you still want to use v4.2....

Hi Felix,

would it be possible to re-enable the backwards compatibility symlinks for Ubuntu 14.04 packages? I am at the point when it would be really convenient to have both older (4.2) and newer (5.5) versions of paparazzi at the same machine (Ubuntu 14.04) without having to use virtual box, docker etc.

Thanks for info.

I only rebuilt the package with the compatibility symlink on 12.04, on 14.04 they are disabled...
So compiling 4.x should work on 12.04... but not on 14.04

The 12.04 package hasn't changed since my last post in this thread: https://launchpad.net/~paparazzi-uav/+archive/ubuntu/ppa/+sourcepub/4695332/+listing-archive-extra

Hi, has something changed with the ppa package?
For some reason even if I install the newest paparazzi-dev package (on Ubuntu 14.04 and Ubuntu 12.04) I get the same error as before:
...
OC pprz.mli
File "pprz.mli", line 170, characters 78-89:

Uploaded a new source package ivy-ocaml_1.3.1ppa3~precise with compatibility symlinks enabled to launchpad...
Should be built and published in the ppa soon.

Ace, that sounds like the best option.

The older version should still be available in the ppa. So you should be able to just apt-get install it and force the old 1.2-3something version.

But I think I will just trigger a rebuild for precise with the compatibility enabled.
When I uploaded new packages to trigger the arm build I forgot that it would be good to enable that for precise only.

Will do that when I get home.

Thanks Felix for quick reply.

If I install ivy-ocaml 1.2 as described here (http://wiki.paparazziuav.org/wiki/Installation/FromScratch#Ivy-OCaml) how do I enable it?

Also, will I be able to use paparazzi 5.4 at the same time as paparazzi 4.2?

Hi Michal,

the latest version of ivy-ocaml is built without the backwards compatibility symlinks.
So you could either install an older ivy-ocaml package (version 1.2x), build it from source and enable them again or create the symlinks yourself by hand.

Or I add the symlinks only for the precise package again...

It is a bit annoying though if you have a Paparazzi v5.x and the symlinks, it always warns that the interfaces exist in multiple dirs...

Cheers, Felix

Hi all,

I have a legacy version of paparazzi (essentially 4.2 with minor changes in the ap code), and I need to make it run on a new machine with Ubuntu 12.04.

I followed the install guide from wiki:

sudo add-apt-repository ppa:paparazzi-uav/ppa
sudo apt-get update
sudo apt-get install paparazzi-dev
sudo apt-get install paparazzi-arm-multilib

when I run make in the ppprzi directory I get the following error:
...
OC pprz.mli
File "pprz.mli", line 170, characters 78-89:
Error: Unbound module Ivy
make[1]: *** [pprz.cmi] Error 2
make: *** [lib] Error 2

From wiki (http://wiki.paparazziuav.org/wiki/Installation/FromScratch#Paparazzi_Main_sourcecode) it looks like some it is some missing Ocaml/Ivy linking.

Any ideas how to fix it? I already have latest paparazzi (master) running on the machine.

Regards
Michal
