Description

OK, I know this looks like a crazy scenario, but here we go:

I'm trying to run JRuby in the environment described above and I get this error:
Could not load FFI Provider: FFI not available: Could not locate stub library (/jni/ppc-Linux/libjffi-0.6.so) in jar file (LoadError)

What can I do ? Should I provide you with a build for that arch ? Please let me know, I would be happy to help.

Antoine, please take a look at JRUBY-3915 for instructions on how to provide the bindings. Once you have the compiled JAR file, just attach it to this bug report.

Antoine, thanks for the JAR. I've added it in rev. d5b724d on master branch. Please build the latest master and check that it all works as expected, that the native stuff is properly loaded on ppc-Linux platform and that it works.

Things like jruby -e 'puts $$', etc. And, running 'ant spec' and 'ant test' would nice too. Thanks!

Vladimir, here are two runs of ant clean test with jruby. Looks like it fails

Should I try ant spec too ?

This could be unrelated to the jffi change though. Could you try with and without the jar file and see the diffs.

Is simple jruby -e 'puts $$' works?

Trying out ant spec would be interesting exercise as well.

Here goes:

$>jruby -e 'puts $$'

I'm trying the various ant combinations you mention as well.

Interesting, looks like 'puts $$' returns rather weird process id...

Here is the result of ant spec. I think it hanged when it tried to dump. I had to kill it.

Could you also try the following (but first please update to the very latest master branch):

  • jruby samples/ffi/gettimeofday.rb
  • jruby samples/ffi/qsort.rb

Does it work?

No need to remove anything, the JAR should be in the main repo already. Just try to pull, then 'ant clean' and then 'ant'. And you should be set.

At the minimum, I expect that the FFI provider should be able to load.

OK, I tried deleting my current jruby checkout, then did a new clone and ran 'ant' at its root.

I still get the same error.

What am I missing ? I'm running the jruby executable in the bin folder of the git checkout, am I supposed to use an other jruby executable ?

I typically add the JRuby's bin directory to my PATH and then just invoke jruby.

At a minimum, jruby -v should work. jruby -e "require 'ffi'" should work, and the samples suggested above should be functional (ideally).

The error about not finding /jni/ppc-Linux/libjffi-0.6.so is interesting, since in your JAR file I only see libjffi-0.6.a, which is probably wrong, there should be shared lib there *.so, not the static *.a one.

Could you please check your environment and rebuild the ppc-Linux.jar so that it should contain the *.so file?

Antoine: This looks like it may be a bug in jffi, in the native code...but it does appear to be loading now.

Are you able to at least do "jruby -e "require 'ffi'"? If you can do that, it's at least loading the native bits.

I just tried that. It seems to be working (as it is not complaining).

You might want to clone the latest jffi 1.0 tree (http://github.com/wmeissner/jffi), build it and drop both jffi.jar and jffi-ppc-Linux.jar into build_lib, then rebuild jruby.

There were some bugs in the older version of libffi used in jffi-0.6 that seemingly affected powerpc on linux (but didn't seem to affect AIX).

Of course, there could still be other big-endian bugs in jffi itself somewhere. There are only three people that run it on non-x86/86_64 arches, so it doesn't get a lot of testing.

Here is a new attempt with the latest trunk on jruby and the 1.0 jffi code.

Looks like tests don't pass because a launcher gem can't be installed.

Antoine, since those simple tests work, you might want to run the whole ruby-ffi test suite.

git clone git://github.com/ffi/ffi.git ruby-ffi.git

cd ruby-ffi.git

# build the test helper lib
rake build/libtest.so

/path/to/jruby.git/bin/jruby -S spec spec/ffi

I think I fixed this in jruby commit 1065897e5ecce3c6767471e86541f5ec917db636

Just update to the latest jruby (no need to rebuild jffi) and see if it fixes it.

You're going to have to debug this one yourself.

Have a look at src/org/jruby/ext/ffi/jffi/CallbackManager.java line 493

Where you see the code

        case BOOL:
            return runtime.newBoolean(buffer.getByte(index) != 0);

You'll want to either use a debugger and put a breakpoint there, or add some debug trace to print out the value being read in for the argument.

For a false value, it should naturally be all bits cleared, for a true value, it should have the value 0x01. You might also want to print out 2, 4, 8 bytes at the same index and see what values are there.

Hmm. I tried something stupid and replaced that line by "return true". It didn't help though.

Added cut down version of ruby-ffi callback spec for testing bool arguments to callbacks.

Run this from the ruby-ffi.git dir (it needs to load the libtest.so).

Can you print out the values (in hex) that fromNative is reading for bool arguments?

You might also want to put some more trace in AbstractCallbackProxy#invoke() to make sure it is really getting called.

Also, make sure you're doing 'ant clean' so you get a full rebuild of jruby.

Wayne, I apologize: cleaning and rebuilding jruby, all specs pass as they should.

I guess we are good to go now ?

I committed your jffi-ppc-Linux.jar in commit 70acb3c1d6570be6d142f159a4d0b1c036d7fe38

For an extra sanity check, can you update jruby and make sure you have a clean tree (i.e. no mods, its using the checked in version of jffi-ppc-Linux.jar) then rebuild & test jruby, and run it against the FFI specs again.

If that all works, then I say we're good to go.

I have failures while running ant clean test, see attached files. All specs pass.

I worked with Wayne extensively yesterday and we got to the point where the lib is created in 64 bits allright, but we could not run the specs.

Without a 64 bit JVM I get this:

So status on this: we have been successful doing the 32 bit version of the jar, but there are issues with 64 bit for some reason (see the gists in my previous comment).

We are good to go with 32 bits for now.

Resolving as incomplete. We have had many iterations of jffi stuff since this time, so if it's not working please open a new bug.
