[Wala-wala] Cannot run Examples

[Nicolas Cardozo]

Hi, 

Im following the getting started guide in the repo pages, but I cannot reach to run any of the examples.

I imported the project to Eclipse using import from Gradle, but whenever i try to launch any of the example launchers I get an error similar to 

Launch configuration PDFTypeHierarchy references non-existing project com.ibm.wala.core.tests

(modulo de example to execute)

I tried to run all the build gradle tasks in the build folder from the gradel tasks view, and the build for each specific project, but nothing seems to be working 

I also read previous post related to launching problem and followed the solutions there, and still nothing.

Does anyone have an idea of what I could be doing wrong.

Im running on a mac OSX, with eclipse 4.18. I’m trying different WALA releases, all of them with different problems, currently trying 1.3.8 (none of the latests one worked for me)

Hi Nicolás,

Sorry you're having trouble with Eclipse.  Unfortunately, none of the main WALA developers use Eclipse regularly anymore and so it's quite possible the launchers have bit-rotted.  Have you seen the WALA-Start project?

https://github.com/wala/WALA-start

That is based on a more standard Gradle configuration, and it includes some sample drivers.  Does that work for you if you do a Gradle import of that project into Eclipse?  Note that using WALA-start allows you to get started without building WALA from source.

If you have a specific analysis that you're trying to run with WALA, let us know and I can try to point you at a relevant driver example.

Best, Manu

Hi Manu,

Thanks for the info.

The WALA-start project works appropriately (I can run the compileJava command without any problem) but am a bit at a loss about what to do after that.

I want to use the points to analysis for JavaScript. My end goal is to extend/use this analysis on programs using traits (traits.js) to compose objects. My idea is to use the results (as a start) to reason about program completeness, much in the way it is done for Java programs (https://link.springer.com/chapter/10.1007/978-3-540-31985-6_21)

Hi Nicolas,

This is a sample driver for building a call graph for a JavaScript file:

https://github.com/wala/WALA-start/blob/master/src/main/java/com/ibm/wala/examples/drivers/JSCallGraphDriver.java

Hopefully that can get you started?  Also there is this documentation page on JavaScript analysis:

https://github.com/wala/WALA/wiki/Getting_Started:JavaScript_frontend

Please let us know if you have further questions.

Best, Manu
