Error while building on ubuntu machine

[najiJazzar]

I'm trying to build the repo as descriped. I'm using a 32-bit ubuntu-16-04 machine. So I prepared the installation using the --desktop option and built it using the --platform=desktop option. Then from the releases directory I tried to lauch the Snap4Arduino but the following error appeared : ./Snap4Arduino.desktop: line 1: [Desktop: command not found ./Snap4Arduino.desktop: line 5: -c: command not found ./Snap4Arduino.desktop: line 8: Snap!: command not found

Am I doing something wrong ?

The executable is Snap4Arduino, not Snap4Arduino.desktop. The latter is a launcher for Nautilus and other file managers (I think, I'm not a GUI user...)

So, you should either do:

./build --platform=desktop/gnu/32 --run

And the build script will automatically launch Snap4Arduino after building it, or:

cd releases/desktop/gnu/32
./Snap4Arduino

Or, after having successfully built Snap4Arduino, you can always call the build script like this:

./build --rerun

Which will look for the appropriate build for your system and launch it.

Hope it works! :)

@jguille2 I knew the desktop file would bring issues! ;)

[bromagosa]

@najiJazzar I've renamed the GNU/Linux executable, now it's called run.

You can still use all these ways to run Snap4Arduino by using the builder, except that the second one now looks like this:

cd releases/desktop/gnu/32
./run

[najiJazzar]

@bromagosa The problem is that the executable (Snap4Arduino or run )isn't generated. The --run option gives me the following error:

_ERROR: Auto-running is not supported for your current architecture or operating Your system reports this is an i686 machine. This script can only auto-run for x8664 and i386 under GNU/Linux. In other systems, please build Snap4Arduino by using ./build --platform=TARGET and then manually navigate to the releases directory.

And the result of ls releases/desktop/gnu/32 is: icons launcher.sh LICENSE Snap4Arduino.desktop_

I don't know why "run" doesn't appear !

[bromagosa]

I see, that's the same issue @jguille2 had a while ago, and IRC it had to do with the NodeJS version he had installed in his machine. Can you paste here what's the output of runnning node --version and npm --version?

Thanks!

[najiJazzar]

It seems like this is the problem, that's embarrassing, I didn't have the NodeJS I'll redo the steps, hopefully now it will work. Thanks a lot

[bromagosa]

Nah, that's my fault. I should have documented the prerequisites... let me get to that :)

[najiJazzar]

@bromagosa Am sorry, but also with downloading the NodeJS and the other things you've mentioned in the new description, it still not working with me :( same problem, there is no executable. here is the versions you've requested before :

node --version = v4.2.6 npm --version =3.5.2

[bromagosa]

Your NodeJS version is too old I believe, mine is v6.1.0.

Try upgrading it, you can follow the instructions from https://nodejs.org/en/download/package-manager/ to install v6.

Hope it works :)

[najiJazzar]

now I have v6.7.0 and the executable is still missing. any thoughts ? Sorry for bothering you :\

[bromagosa]

No worries, that's what I'm here for :)

Did you run ./prepare --all again? Some packages will need to be rebuilt after installing the new Node version.

[najiJazzar]

I removed the whole directiory, cloned it again. so yes I did but ./prepare --all when it finishes it gives me this message :

WARNING: Please make sure to place your Snap4Arduino.pem Chromium extension private key under environments/web/chromium I cannot do this for you because, you know, it's a private key ;)

I was ignoring this message since I think I don't need any Chromium-related things I don't know if this creates a problem !

[bromagosa]

Nope, this should not be a problem.

That's weird... what error message(s) does ./build --platform=desktop/gnu/32 give out?

[najiJazzar]

no error messages the last line printed is a green-colored Done!

[bromagosa]

wow.. and still there's nothing under releases/desktop/gnu/32?

@jguille2 is this what was also happening to you? How did you fix it?

[bromagosa]

Also, can you please run this and paste the contents of the tmp directory here?

./build --platform=desktop/gnu/32 --keeptmp

[najiJazzar]

Unfortunenately yes, it still missing.

here is the ls tmp result:

[bromagosa]

Hmm... the tmp directory looks perfectly fine to me. It's exactly what should be there.

Let's break this down step by step. Here's my whole output, can you check if there are any differences to yours?

[najiJazzar]

wow, there are files that aren't found ! here is what I get:

[bromagosa]

Now it starts to make sense. nw-builder is not installed, but that should have been handled by the prepare script. Can you paste the output of ./prepare --nwjs please?

[najiJazzar]

here it is:

naji@naji:~/Snap4Arduino$ ./prepare --nwjs Pulling nwjs.io builder (nw-builder) npm WARN deprecated minimatch@0.2.14: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue npm WARN deprecated minimatch@0.3.0: Please update to minimatch 3.0.2 or higher to avoid a RegExp DoS issue /home/naji └── nw-builder@3.1.0

[bromagosa]

What's under environments/node_modules/nw-builder/bin/ ?

[najiJazzar]

there is no such directory in mine this directiory instead /Snap4Arduino/environments/desktop/node_modules have : async bindings browser-serialport debug es6-shim firmata minimist ms nan optimist sf wordwrap

[bromagosa]

What about in environments/node_modules?

[najiJazzar]

environments only have desktop embedded web

[bromagosa]

That is really weird, but what it seems is that npm has installed nwbuilder somewhere else in your system.

This will take a while, but can you run find ~ -name nwbuild ?

[najiJazzar]

Here what it says : /home/naji/node_modules/.bin/nwbuild /home/naji/node_modules/nw-builder/bin/nwbuild

should I move them ?

[bromagosa]

Yep! Just move the whole node_modules directory inside environments, and that should make ./build work!

[najiJazzar]

booooyah!! finally it wooorks :D thanks a lot really for your precious time :)

[bromagosa]

Right on! There we go!

Now I should find out why was this happening in the first time though. I guess I could force prepare to install these packages in the working dir.

Thank you too for helping debug it! :)
