Problem with build/compile instructions (in Ubuntu)

@dipspb , read carefully ! http://ardupilot.org/dev/docs/building-px4-for-linux-with-make.html#setup !!
You miss an important step that install everything on your computer for compiling ! ( Tools/scripts/install-prereqs-ubuntu.sh -y)

For information, waf install nothing. Doing waf configure only check if all dependencies are present and prepare the build.
On your try, you try to build for px4-v2 that use arm-none-eabi GCC compiler.
You can see that your first error is Checking for program ‘arm-none-eabi-ar’ : not found
Could not find the program [‘arm-none-eabi-ar’] . So you are missing the compiler ! (and probably many other dependencies !)

Give another try by reading carefully step by step and you can get rid of vagrant ^^

@dipspb ok I will try this , but does it first require a computer that is capable to run VirtualBox and Vagrant ?

Thank you for your point, but…

Isn’t it a confusing that toolchain installation step is described on a page “Building ArduPilot for Pixhawk/PX4 on Linux with Make what is recommended to don’t follow for 3.4 on page “Building the code” ?!

Code building has changed for newer releases to use waf build tools, replacing make

I can see it reported a lack of arm GCC compiler, it was exactly my point.

Vagrant is used to run SITL and it is good tool to use it for build on any compatible platform. It makes it possible to don’t install bunch of tools and libraries on your OS just to build the image. Moreover it avoids potential conflicts among installed tools/libraries versions at the moment you will need to install more recent versions as soon as new ardupilot release will be available. I definitely sure, Vagrant worth to be considered as a good, not an evil.

Instructions I provided you so far not require to use Vagrant and VirtualBox. Just try them as it is.

@dipspb - I think you’re confused about the terminology around toolchain, dependencies and make. The line that you quote has to be taken in context, the next line says:

In most cases the build dependecies described for make are the same, the only part of the instructions changes is the issue of the waf build commmand.

waf isn’t some magical command that sprinkles fairy dust and does everything for you, it’s just a replacement for make. You cannot compile something without a compiler toolchain, which involves installing dependencies. So the instructions remain the same, except that you replace the make command with the waf commands.

Questions and process like this is really useful for the community as it gives everyone a chance to clarify and improve the build or documentation if it needs it.

@dipspb - I would recommend that you follow the official docs and post any problems you have, and we’ll do our best to help you. They should work, and they are straight forward.

Thank you for pointing it. This story is not about me. I able to compile all needed tools from sources w/o any package manager used, no problem. I just described how it may looks like for inexperienced user like @maxmay. I believe it’s not a big problem to refer to mentioned Tools/scripts/install-prereqs-ubuntu.sh script on waf page.

Just attempted to follow in exact way all steps using waf and prerequisites as they documented. Still have no success:

dipspb@ubt1404srv512:~/ardupilot$ 

It would be nice to know what exactly I missed and where missed step is documented.

cmake install is missing from the install-prereqs-ubuntu.sh script. I note that the compiler is a slightly different version from that documented, so it’s probably worth opening a github issue and getting the docs/script updated. Here’s the commands that work on a fresh ubuntu VM for me:

sudo apt-get -qq -y install git
git clone https://github.com/ArduPilot/ardupilot.git
cd ardupilot
git submodule init
git submodule update
Tools/scripts/install-prereqs-ubuntu.sh -y
sudo apt-get install cmake
. ~/.profile
./waf configure --board px4-v2
./waf copter

This is exactly as documented, except for the missing cmake dependency.

Thank you, I know. But one more time, it’s not about me… Of course I will submit the issue.

Are still sure instructions are ok?

@maxmay I believe you need to follow recent instructions provided by @fnoop as a most correct approach for this moment.

@dipspb - if you have some ideas to improve the build system, make it more generic or easier for beginners etc, why don’t you chat with the developers on gitter or post in the Development forum? I’ve only had a couple of small interactions with the devs but they’re super nice and friendly, and really keen to help new people who want to get involved. They answered my basic and stupid questions and helped me out to submit a small 3 line patch when it would have been much quicker to do it themselves.

@dipspb @fnoop thank you both for the help identifying the issue. Both provided valuable feedback. I just submitted a PR to add the missing dependency: https://github.com/ArduPilot/ardupilot/pull/5106. This will be backported to 3.4.1.

In future we will need to streamline our scripts to install dependencies so this kind of issue doesn’t happen anymore.

@maxmay I hope the instructions they provided are enough.

@dipspb @fnoop @lucasdemarchi …I will try the last fnoop instructions, and give results here, and if it works I will contribute $ to ardupilot.org as promised.

I just tested on an empty Ubuntu 14.04 container and it worked fine building with waf.

@dipspb @fnoop @lucasdemarchi S**T! I am the only one it does not work. let me increase my donations to ardupilot. my vitual 32 bit machine AND virtual 64 bit machine give me same result, ie. 2 tries :

ok, I missed to tell you 2 steps:

sudo apt-get install software-properties-common

to install the missing command. And

add-apt-repository "deb http://archive.ubuntu.com/ubuntu $(lsb_release -sc) main universe restricted multiverse"

to enable all repositories. I think those come pre-installed on the Desktop version, that’s why people don’t notice them. I’m not an Ubuntu user… I just created a container in my distro in order to reproduce your issue and thought I needed these other 2 commands because of the way I setup the container, sorry.

Could we have all steps together documented on a waf page? Sort of TLDR chapter.
It’s pretty hard to agree that instructions are straightforward because each new attempt leads to discovering more missed steps.

@dipspb wait an hour I am making the final test, with a final instruction list

the build instructions are one thing. Setting up the distro is another thing. The right place would be in the wiki, to replace the old instructions. I’d love for someone to step up and solve this issue: Update build instructions · Issue #565 · ArduPilot/ardupilot_wiki · GitHub
