Hello Wala Team.

I cloned Wala like described here from the git repository out of eclipse (Juno):
http://wala.sourceforge.net/wiki/index.php/UserGuide:Accessing_WALA_Using_Git#Cloning_WALA

Afterwards I got a mass of import errors because some classes are not
found (not available - the little red x on the eclipse projects).

This list said for some projects it is okay, but the major projects
have to compile automatically (like com.ibm.wala.core or
com.ibm.wala.shrike) but they don´t.
Some examples of classes which are not found:
- inside wala.core: com.ibm.wala.shrikeBT.IInvokeInstruction (missing
wala.shrikeBT package)
- inside wala.shrike: com.ibm.wala.util.collection.Pair (missing
wala.util package)

Any suggestions?
It seems that the build path was not cloned from github properly. the
shrikeBT package for example is available in project
com.ibm.wala.shrike > com.ibm.wala.shrikeBT.
So it seems that I have to set this project in the build path of wala.core.

Is there somewhere a list what to do or which build path I have to set
to the core project? Or is it up to me to fix it manually?

PS:
Eclipse Juno
Java JDK 7
Windows 7 x64

Hi Ulf,

My guess is that you have the wrong flavor of Eclipse installed.  You should get Eclipse Classic:

http://www.eclipse.org/downloads/packages/eclipse-classic-42/junor

The Eclipse IDE for Java Developers distribution does not include the Plugin Development Tools.  Since WALA projects are plug-in projects, you need the PDT in order for the code to build.  
Also, we haven't tested with Eclipse Juno yet; I'm still on 3.7.  So there may be some issues there (but hopefully not).

Thanks,
Manu

Hi Manu.

Thanks for your answer.

I forgot to run the ant-scripts and as well I reinstalled PDT. Than all classes compiled as suggested without errors but one class: com.ibm.wala.fixpoint.IntSetVariable.

At line 30ff "other.V" is used. But variable V was set to "private" (line 26). Eclipse said, that "other.V" is not visible.
I changed line 26 to default visibility - no error anymore.
But I´m not sure if this was just a bug or if it was suggested by the programmer.

Hi Ulf,

This compiles fine for me without any changes using Eclipse 3.7.  Not sure why it's not compiling in your case, but if that change fixes it for you, maybe you can just maintain the change locally.



Thanks,
Manu
