Need help to building browser plugin demo

General JUCE discussion
#1

I tried to build the browser demo from the latest tip in Visual Studio 2010, but I get this error:

 

1>  juce_browser_plugin_wrapper.cpp
1>d:\myname\juce\juce\modules\juce_browser_plugin_client\wrapper/juce_NPAPI_GlueCode.cpp(743): error C2552: 'argStruct' : non-aggregates cannot be initialized with initializer list
1>          'juce::var::NativeFunctionArgs' : Types with user defined constructors are not aggregate
1>

which corresponds to this line

const var::NativeFunctionArgs argStruct = { object, params.params, (int) argCount };

 

I'm not familiar at all with the browser part of JUCE, or web programming at all, was just curious to see what it was, but I sadly cannot even get the demo to build,

 

any advice?

 

#2

Ah, sorry, I changed that structure recently and hadn't checked the plugin build. Try again now!

#3

trying now,

now I get this

1>RC : fatal error RC1110: could not open ..\..\..\..\modules\juce_browser_plugin\wrapper\juce_NPAPI_WinResource.rc

The folder is called juce_browser_plugin_client, but I don't know where to change it, I already changed it in JuceHeader.h for another include, so you might want yo update that one too

 

#4

damn.. I guess you can see that I don't spend too much time on that project! Ok, have updated the paths now (but can't test a Windows build myself right now, so can't guarantee that covers every other problem!)

#5

Thanks, I can build it now with some warnings,

But I'm not sure how to run it, I copied it to C:\Program Files\Mozilla Firefox\plugins (which did not exist), and also to "C:\Program Files (x86)\Mozilla Firefox\Plugins" which already existed, and opened test.html in FF Chrome and IE8, but I only got the buttons, and some empty space above it.

 

By the way here are the build warnings if you are interested

Oh wait, could this be an architecture problem? I'm running win7 64bits

#7

Yeah, this is why I stopped maintaining the plugin build - when all the browsers went to 64-bit, they began sandboxing the plugins, which made it impossible to embed the plugin's window in the browser - hence the blank space. The only workaround would be to write a whole new rendering + mouse-event system that works via their sandboxed APIs, and would make it impossible to embed useful stuff like openGL, DirectShow, etc.

You can still write non-GUI plugins, so it's handy for audio, but you'd be better off writing the UI bit in javascript.

#8

Ok thanks for the explanation, I didn't have a particular goal in mind, was just trying it out. I guess for making browser/webbased stuff there is other tools than JUCE,

 

Although one can dream of a HTML5 "build" option....

Although one can dream of a HTML5 "build" option....

Yeah, I'd love to have enough time to have a go at that!

#10

This would also improve the usefulness of JUCE as a game engine/framework. I read in another topic some time ago you were also interested in that.

 

But yeah if you have to start from 0 I can imagine it's a lot of work.
