"Uncaught translation error" when transforming Kawa-compiled classes with dex

"Uncaught translation error" when transforming Kawa-compiled classes with dex

[Kay Zheng]

Hi Per,

I tried building a simple skeleton Android app against the master
branch, targeting Android API level 21 (Android 5.0). The compilation
went well, but there's this ambiguous error when classes are being
transformed to dex files:

    Uncaught translation error: com.android.dx.cf.code.SimException:
local variable type mismatch: attempt to set or access a value of type
int using a local variable of type gnu.mapping.CallContext. This is
symptomatic of .class transformation tools that ignore local variable
information.

I don't really understand this error message, but since
gnu.mapping.CallContext is part of Kawa, I'd try and post it in this
mailing list.

The source code for the skeleton app is on
https://github.com/l04m33/KawaAndroidTemplate

And here's how I built Kawa (I didn't install JDK 6, and used OpenJDK
8 instead, thus the explicit JAVACFLAGS):

    $ cat rebuild-kawa-latest-android.sh
    #!/bin/sh

    cd ./Kawa-latest-android

    if [ -f 'Makefile' ]; then
        make clean
        make distclean
    fi

    git checkout -- .
    git apply ../kawa-javacflags.patch

    ./autogen.sh
    export JAVACFLAGS="-g -source 1.6 -target 1.6"
    ./configure
--with-android=/home/user/android_sdk/platforms/android-21/android.jar
\
                --disable-xquery \
                --disable-jemacs \
                --with-java-source=6
    make

And the content of kawa-javacflags.patch:

    $ cat kawa-javacflags.patch
    diff --git a/Makefile.am b/Makefile.am
    index da9e490..a0df1a3 100644
    --- a/Makefile.am

a new thread.

Re: "Uncaught translation error" when transforming Kawa-compiled classes with dex

[Kay Zheng]

Hi Sonny,

Thanks for the suggestion.

I carelessly left out an important fact, that I've compiled the same
app against the 2.4 branch this way and it worked well, so I'd suspect
it's some changes in Kawa that caused this error. Not necessarily a
bug, though.

Regards,
Kay Z.

Hm.  It would be helpful if the error message would say what class and
method it were complaining about.

A work-around for Java code would be to Compile with -g:lines (-g:none) to
suppress of the LocalVariableTable attribute, since that is what dex seems
to be complaining about.  Unfortunately, Kawa doesn't have a comparable option
for Scheme code. It shouldn't be hard to add.

Thanks - I fixed this in my sources.  I'll check it in after I've tested it.

Re: "Uncaught translation error" when transforming Kawa-compiled classes with dex

[Kay Zheng]

Hi Per,

Indeed it had something to do with local variable info. I added the
following snippet to the android section in build.gradle based on your
assertion, and the error went away:

    dexOptions {
        additionalParameters '--no-locals'
    }

I also enabled the debug logs in the dx command, and here goes the
full error message (long lines, hopefully the text won't get messed
up):

Uncaught translation error:

I do see a problem.  The method stringConcatenateReverse$SlShared$V in srfi13.class has
the following:

Attribute "LocalVariableTable", length:92, count: 9
   slot#0: name: string-list, type: java.lang.Object (pc: 0 length: 662)

   slot#3: name: end, type: java.lang.Object (pc: 124 length: 538)
   slot#4: name: len, type: java.lang.Object (pc: 300 length: 247)
   slot#5: name: nzlist, type: java.lang.Object (pc: 300 length: 247)

   slot#7: name: $ctx, type: gnu.mapping.CallContext (pc: 300 length: 247)
   slot#7: name: slen, type: int (pc: 340 length: 67)

Notice slot 7 is used for two different variables, of different types - and their
PC ranges overlap.  Hm.

Thank you! I think the fix worked, and the APK was built successfully.

The app failed to run though. A ClassNotFound exception regarding my
main activity, much like what Sonny To reported in another thread a
while ago. But this is most likely a separate issue, not necessarily
relevant to Kawa. I'll try digging around and see if I can find
anything.
