Problem with java bindings in VTK 9

Gilthalas · April 2, 2020, 7:55pm

Things are getting past where they were before, will keep you updated.

OK @ben.boeckel one, maybe last?, problem - when I try to run it, pointing to the jnilibs as needed (setting DYLD_LIBRARY_PATH, setting java.library.path) the jnilib want to reference the dylib files, which it can’t find because they are no longer in that directory.

If I copy the dylibs from 2 directories up into that natives folder, and run, it doesn’t complain about the missing files, but then crashes horribly with the vtkGenericOpenGLRenderWindow crash (which I have a fix for… I need to make a MR for it… basically you need to ask for the best GLProfile you can instead of the default… I’ll see if I can do that tonite)

If you can tackle the jnilibs, I’ll get a MR in for the hard crash (and hope it still works!)

ben.boeckel · April 3, 2020, 11:49am

Could you paste the result of:

otool -l $any_jnilib | grep -A4 LC_RPATH

(the 4 may need tweaking to get the actual value). It should be @loader_path/../... I guess the output of otool -L $any_jnilib may also be useful.

Gilthalas · April 3, 2020, 12:51pm

Sure. here is the grep result:

otool -l libvtkRenderingParallelJava.jnilib | grep -A4 LC_RPATH
          cmd LC_RPATH
      cmdsize 32
         path @loader_path (offset 12)
Load command 35
          cmd LC_RPATH
      cmdsize 32
         path @loader_path/../../ (offset 12)

and here is the full one:

otool -l libvtkRenderingParallelJava.jnilib

OK, so that’s what I’d expect. What is otool -L $any_jnilib saying? I wonder if we’re not getting @rpath/ library IDs…

Gilthalas · April 3, 2020, 1:41pm

Here’s what that gives below. Note that in my custom script I’ve using (which really just lets me set cmake parameters without going through ccmake first), I’ve had to add the following flags to get these to generate properly in the past

-DCMAKE_INSTALL_RPATH_USE_LINK_PATH=ON
-DCMAKE_MACOSX_RPATH=OFF

Maybe they aren’t needed anymore? Anyone otool output below:

ben.boeckel · April 6, 2020, 2:29pm

Yes, please try with those rpath settings left to the default values.

ben.boeckel · April 8, 2020, 6:26pm

Any update if you don’t set those rpath variables? I’d like to merge what’s there so it can make it into 9.0.

Gilthalas · April 8, 2020, 6:40pm

I’ll run that tonite and let you know.

Gilthalas · April 9, 2020, 2:41pm

Sorry for the delay; still getting errors where the loading of the jnilib tries to reference the dylib. Were you able to get the demo (JoglConeRendering) to run correctly?

ben.boeckel · April 9, 2020, 2:52pm

I’d have to get a Mac to test that part. I’ll try the build on a Mac if I can find one with Java around and see if I can’t get the rpaths to look right there.

ben.boeckel · April 9, 2020, 4:48pm

Hmm. With stock settings I’m seeing:

The install tree looks the same; looking into that. But it looks OK here. I’d look to see if you have something not making @rpath/ be used in your build. What CMake are you using?

OK, so the install tree looks fine too if I don’t use whatever install_name_tool macports is shipping. I’m going to put this down to some other configuration setting issue and merge the branch as-is. We can follow up with further fixes if needed.

OK I’ll take a look at it again soon. Can you elaborate on what “stock settings” you are using - I assume this refers to the cmake settings?

ben.boeckel · April 10, 2020, 2:23pm

“Stock” as in I only set the Java wrapper settings and manipulate module selection. No CMAKE_ variable changes.

Hey @ben.boeckel did you try running the sample Java code (like JoglConeRendering) after building your libs? I got my building correctly (@rpath is now there) with the latest master, but am getting some nasty Invalid framebuffer operation errors when trying to run the demo.

ben.boeckel · April 17, 2020, 11:54am

How can I run the JoglConeRendering example?

Seems to work just fine on Linux. Looks to be some spheres of different colors that pop in and out of existence?

Sebastien_Jourdain · April 17, 2020, 12:09pm

Actually the last argument (the main to execute) should be vtk.sample.rendering.JoglConeRendering rather than vtk.sample.Demo but at least you have the rest of the command line.
