compile errors

[stutteringp0et]

I've forked your project and made some modifications to get it to compile, but I'm not familiar enough with Dart to figure these out. I know it's been several months since you've updated it, but I hope you'll consider giving it a refresh.

This is where it's failing after my very slight modifications.

src/mod_dart.c: In function 'bool IsolateCreate(const char_, const char_, void_, char__)':

I bypassed the Dart_Initialize error by adding a third argument 'NULL' to the function, and now I get errors on these two lines in the IsolateCreate function:

Dart_SetNativeResolver(Builtin::kBuiltinLibrary);
Dart_SetNativeResolver(Builtin::kIOLibrary);

src/mod_dart.c: In function 'bool IsolateCreate(const char_, const char_, void_, char__)':
src/mod_dart.c:63:50: error: cannot convert 'Builtin::BuiltinLibraryId' to 'Dart_Handle {aka Dart_Handle}' for argument '1' to '_Dart_Handle* Dart_SetNativeResolver(Dart_Handle, Dart_NativeEntryResolver)'
src/mod_dart.c:64:45: error: cannot convert 'Builtin::BuiltinLibraryId' to 'Dart_Handle {aka Dart_Handle}' for argument '1' to 'Dart_Handle Dart_SetNativeResolver(Dart_Handle, Dart_NativeEntryResolver)'
apxs:Error: Command failed with rc=65536

Again, the issue is - not enough arguments (I think).

Since Builtin:kBuiltinLibrary and Builtin:kIOLibrary aren't Dart_Handle types, what is the first argument supposed to be?

If I comment these lines, the module compiles - but fails to load with this error:
mod_dart.so: undefined symbol: __cxa_pure_virtual

Apologies for the late response, I think this should be fixed now. (Mostly in d1fe3fc). The Dart APIs and development environments are a moving target (just upgraded to Mac OS 10.8), and I've been quite busy with work.

I added a shutdown callback, and switched to the new API for setting native resolvers following the example that introduced the change: https://chromiumcodereview.appspot.com/10532123/diff/14001/runtime/bin/main.cc?context=10&column_width=80

There also seems to be a new dependency within dart on a web_gen module within dart, which took some fiddling to get right.

Let me know whether this works for you!

After updating to the latest dart version available, and updating your package to this latest update - I'm still getting:
undefined symbol: __cxa_pure_virtual

Searching that error gives not much insight into the problem...

I appreciate the update!

[stutteringp0et]

the latest changes (switch to runtime directory) I'm getting the same issue....
mod_dart.so: undefined symbol: __cxa_pure_virtual

[stutteringp0et]

As you mentioned, dart is a moving target (there's a pun in there somewhere). So maybe I should wait until it stabilizes instead of trying serverside right now.
