Using Juce in a 64 bit VST plugin (bis)


#1

Hi list,

I’m really struggling to get my 32/64-bit VST plugin running in combination with JUCE.
I already upgraded to the very last version of Juce (1.54.27). I only encounter problems in 64-bit hosts (eg. Plogue Bidule, Cubase 6).
It seems to be a problem of shared allocation space between different 64-bit plugins.
Because I couldn’t really find a solution to my problem, I downloaded the tutorial project from the VSTGUI4.0 library.
It uses VSTSDK2.4 in combination with VSTGUI4.0.
I included the juce_amalgamated.mm file in the XCode project, and added the different frameworks Juce needs to compile.
The only thing is that I added a Juce object to the plugin class (a StrinArray in this case). (and the include statement).
Nothing else changed.
This works in 32-bit, but not in 64-bit. It seems to have a problem with clearing memory. The crash logs are included below the code.
When I remove the statement, the plugin work without crash.

#ifndef __TutorialVST2Effect__
#define __TutorialVST2Effect__

#include "public.sdk/source/vst2.x/audioeffectx.h"

#include "TutorialParameters.h"

#include "juce.h"

class TutorialVST2Effect : public AudioEffectX
{
public:
	TutorialVST2Effect (audioMasterCallback audioMaster);

	void processReplacing (float** inputs, float** outputs, VstInt32 sampleFrames);

	void setParameter (VstInt32 index, float value);
	float getParameter (VstInt32 index);

protected:
	float parameters[kNumParameters];
    
    StringArray presets;
};

#endif // __TutorialVST2Effect__

Looks like a pretty straightforward dangling pointer type of mistake to me. Use your debugger!


#5

When I put JUCE_CHECK_MEMORY_LEAKS=0 the crash doesn’t occur anymore in this case (simple example plugin provided in the VST SDK).
I don’t use a pointer… I just put StringArray presets as a class member. How can this lead to a dangling pointer?

Still I have some very random crashes when using JUCE classes in other VST plugin. The debugger doesn’t really tell me a lot more. Is it because I’m accessing the JUCE objects from different threads (Audio and GUI)?

If you’ve been messing with that stringarray from two threads at once, then yeah, that might just possibly be the problem(!)
