Running dart2js from SDK revision 13851 gives the following:

Internal error: No such method: 'uriPathToNative', url 'file:///tmp/tmpQxaBII/pkg/compiler/implementation/dart2js.dart' line 248Using snapshot dart-sdk/bin/../pkg/compiler/implementation/dart2js.dart.snapshot

revision 13679 was fine.

Thanks for the report!

How are you running dart2js? I cannot reproduce this (not even with the SDK from revision 13851). Lowering priority until we have an indication that this is still a problem.

Removed Priority-Critical label.
Added Priority-Medium, NeedsInfo labels.

It looks a bit fishy that your dart2js.dart file is in a temporary directory.

The same way that I have been running dart2js this whole time: It's run
through an ant file <exec> task.

I'm running 'ant generate-JS' from the master branch of dartbox2d.

Running dart2js directly, instead of through ant, I get the same issue:

$ $DART_SDK/bin/dart2js -o example/benchmarks/BenchmarkRunner.dart.js example/benchmarks/BenchmarkRunner.dart

[kasperl]

Do you have any idea where file:///tmp/tmpQxaBII/ stems from? Does this happen no matter what you try to compile? You can also try running dart2js without the wrapper script in SDK/bin/dart2js by doing something ala:

   SDK/bin/dart SDK/pkg/compiler/implementation/dart2js.dart hello.dart

where hello.dart is the simplest piece of code you can think of. Also be aware that you cannot have a space between -o and the file name; see issue #3379.

Running directly works without error.

I have no idea where the /tmp folder is coming from. Once the process ends, that folder does not exist.

I also noted 'Using snapshot ~/sdk/dart-sdk.13851/bin/../pkg/compiler/implementation/dart2js.dart.snapshot' which I haven't noticed before.

When I run through the dart VM directly, I don't get any output about a snapshot being used. Relevant?

I have the same problem. I just downloaded sdk revision 13851. I'm just using the shell script to run it.

I was able to compile using the wrapper script by removing '$SNAPSHOT' from line 26 in $DART_SDK/bin/dart2js.

Before:
exec "$BIN_DIR"/dart --heap_growth_rate=32 $SNAPSHOT "$BIN_DIR/../pkg/compiler/implementation/dart2js.dart" $COLORS "$@"

After:
exec "$BIN_DIR"/dart --heap_growth_rate=32 "$BIN_DIR/../pkg/compiler/implementation/dart2js.dart" $COLORS "$@"

I think the tmp file names is a side-effect of the SDK build process. With a more recent version, it should be something like file:///long_buildbot_path/out/ReleaseIA32/dart-sdk.tmp/...

We should report a bug with the VM team about this: the snapshot should use the file names given on the command line, otherwise, why give them?

But this is not relevant for this bug report. I think this is a problem with snapshots.

[peter-ahe-google]

Assuming AustinCummings95 is reporting the same problem, I'll take a look at SDK revision 13851.

I cannot reproduce the problem and I need the following information:

Revision (see the file revision in the root of the Dart SDK).

OS name and version?

32 or 64 bit?

Revision: 13851
OS: Linux Mint 13
64 bit

[peter-ahe-google]

I can reproduce. It might be an issue with the 64-bit version of Dart.

---

Added Accepted label.

[peter-ahe-google]

This is looking like a build problem. If I try to build the SDK for Linux x64, I run into a compilation with V8. This means that I cannot create 64-bit version of the SDK.

I think I remember that we may have hacked around that by taking the IA32 version of the SDK and copy the x64 version of the into the IA32 SDK. This probably was a great short-term solution, but now we have a snapshot that was generated with IA32 version of the VM being loaded by the x64 version of the VM. Clearly, that doesn't work.

I see two options:

1. We fix the x64 SDK build.
2. We delete the snapshot from the x64 SDK.

dgrove: can you shed some light on the x64 SDK build process?

I'm currently trying option 1 in this CL: https://codereview.chromium.org/11301019

[devoncarew]

Peter, we do currently create the 64 bit SDK using the 32 bit one. See dart/editor/build/build.py, line 901 or so. It's not an ideal solution but it did get us unblocked.

[peter-ahe-google]

I have confirmed this is a problem with the build process of the 64-bit SDK.
