install fails on ubuntu

[amih]

Edit by octalmage:

If RobotJS fails to build, install these packages:

sudo apt-get install libxtst-dev libpng++-dev

---

Original comment:
There's an error, some header .h file missing?

solution is to install X developer tools with:

sudo apt-get install xorg-dev

Perhaps add this to the README file.
never mind, doesn't work on Ubuntu :(

[octalmage]

So far I've only tested RobotJS on Mac, although technically the code is cross platform. The build script probably needs to be modified.

You we're able to get it installed? What part doesn't work? Do you get any errors?

Thanks!

[amih]

After installing the xorg-dev I successfully installed the robotjs but following the demo resulted in error messages:

> var robot = require("robotjs");
undefined
> var mouse=robot.getMousePos();
node: symbol lookup error: /home/amih3/tmp/node_modules/robotjs/build/Release/robotjs.node: undefined symbol: XGetMainDisplay

I hope this helps, thank you!

Could you try installing ibxtst-dev?

sudo apt-get install ibxtst-dev

I believe this should resolve the issue.

[DamonOehlman]

Ah, you mean libxtst-dev (I assume). Still doesn't work but I'm having a look at the build script and seeing if I can work it out :)

[octalmage]

@amih, @DamonOehlman was able to get RobotJS building for Linux and I merged his pull request. Could you try the latest code to see if it works?

@DamonOehlman were there any additional packages needed?

[DamonOehlman]

Nope, xorg-dev was all that was required and I suspect we can get it down to a tighter list also, but I haven't investigated that as yet...

[octalmage]

Awesome!

So libxtst-dev wasn't needed after all?

[DamonOehlman]

I think it was, but was brought in as a dependency of xorg-dev. Let me uninstall xorg-dev and I'll try and identify the specific packages that are required.

[DamonOehlman]

OK, I looks like libxtst-dev is the best package to require as a dependency as bringing it in also brings in libx11-dev which is also required. I did however also specify png and z as required link settings as these were expressed as dependencies in autopy.

[octalmage]

Great, thanks again for your help. I'll get the readme updated and a new version out tonight. z and png may not be needed now, but they will be necessary dependencies as soon as I finish the screen and bitmap modules.

[octalmage]

I'll confirm in a VM and close this out also.

[octalmage]

Now I can start with continual integration and unit testing. I'm excited.

[DamonOehlman]

Nice. Note some changes for travis around the new docker containers around installing APT packages but yeah this should be pretty easy to test there :)

I tried building it on my machine under Ubuntu 14.10 and I ran into a dependency issue with a few items:

One was installing npm install nan for node-gyp.

The other dependency I ran across was a libgd-dev error on node-gyp build which prompted:/usr/bin/ld: cannot find -lpng.

sudo apt-get install libgd-dev resolved the /usr/bin/ld: cannot find -lpng message.
