Air Native Extension Issue: The well-known "does not have a method with the name___"
I'm trying to resolve the error "The extension context does not have a method with the name ____" for a mac-based native extension.
To isolate the problem, I built a simple .framework, following the documented steps including the flat_namespace and weak_framework tags. Happy to provide full build settings if that's helpful.
Here's the description file I use to build the ANE:
<?xml version="1.0" ?>
<extension xmlns="http://ns.adobe.com/air/extension/3.1">
<id>com.example.extensions.Test</id>
<versionNumber>1.0</versionNumber>
<platforms>
<platform name="MacOS-x86">
<applicationDeployment>
<nativeLibrary>Test.framework</nativeLibrary>
<initializer>FWInitializer</initializer>
<finalizer>FWFinalizer</finalizer>
</applicationDeployment>
</platform>
</platforms>
</extension>
To make sure this is not the issue of Flash Builder 4.6, I took the workaround steps detailed here: Problem with Flash Builder 4.6 when debugging native extension for OSX
Here's the framework side:
uint32_t isSupportedInOS = 1;
FREObject getHelloWorld(FREContext ctx, void* funcData, uint32_t argc, FREObject argv[])
{
FREObject result;
const char *str = "Hello World!! This is your DLL talking!";
FRENewObjectFromUTF8((uint32_t)strlen(str)+1, (const uint8_t *)str, &result);
return result;
}
FREObject isSupported(FREContext ctx, void* funcData, uint32_t argc, FREObject argv[])
{
FREObject result;
FRENewObjectFromBool( isSupportedInOS, &result);
return result;
}
void contextInitializer(void* extData, const uint8_t* ctxType, FREContext ctx, uint32_t* numFunctions, const FRENamedFunction** functions)
{
*numFunctions = 2;
FRENamedFunction* func = (FRENamedFunction*) malloc(sizeof(FRENamedFunction) * (*numFunctions));
func[0].name = (const uint8_t*) "isSupported";
func[0].functionData = NULL;
func[0].function = &isSupported;
func[1].name = (const uint8_t*) "getHelloWorld";
func[1].functionData = NULL;
func[1].function = &getHelloWorld;
*functions = func;
}
void contextFinalizer(FREContext ctx)
{
return;
}
void FWInitializer(void** extData, FREContextInitializer* ctxInitializer, FREContextFinalizer* ctxFinalizer)
{
extData = NULL;// added
*ctxInitializer = &contextInitializer;
*ctxFinalizer = &contextFinalizer;
}
void FWFinalizer(void* extData)
{
return;
}
This is compiled as a i386 framework (using LLVM 5.1 – I know they recommend GCC, but it worked for me before for this exact case). I create the ANE as follows:
export PATH=$PATH:/Applications/Adobe\ Flash\ Builder\ 4.7/sdks/4.6.0/bin
JAR -xf TestSDK.swc catalog.xml library.swf
adt -package -target and Test.ane description.xml -swc TestSDK.swc -platform MacOS-x86 library.swf Test.framework
It seems as if the initializer never gets called. I know I got it to work this way before, but I've spent hours without any progress trying to figure out what's wrong in this setup. Any help is greatly appreciated.
