Compile DSP networks as dll - issue with recent commits

[Dan Korneff]

Just updated to the latest commit and I'm having issues compiling DSP networks I created with an older version of HISE.
Seeing this warning:

C:\Test\DspNetworks\Binaries\Source\Main.cpp(86,1): warning C4190: 'getError'
has C-linkage specified, but returns UDT 'scriptnode::Error' which is incompatible with C [C:\Test\DspNetworks\Binaries\Builds\VisualStudio2022\Test_DynamicLibrary.vcxproj]

The compilation completes and generates a dll, but when I reload HISE, SNEX nodes still show as uncompiled.

[Christoph Hart]

@Dan-Korneff What does Tools -> Show Network DLL info show?

[Dan Korneff]

@Christoph-Hart

{"File": "Test11.dll",  "Loaded": true, "Valid": false, "InitError": "Can't find DLL file C:\\Test\\DspNetowrks\\Binaries\\dll\\Dynamin Library\\Test11.dll", "Nodes": []}

I can confirm that the dll file actually exists in the folder.

[Christoph Hart]

@Dan-Korneff what‘s Dynamin Library?

[Dan Korneff]

@Christoph-Hart Type-o. I'm not able to copy/paste from the DllInfo popup. Should Say Dynamic Library

[Christoph Hart]

Ah, OK, this error message appears if the file can't be found or if it isn't a valid DLL file that can't be opened. What happens if you compile another project DLL?

[Dan Korneff]

@Christoph-Hart When compiling a wrapped SNEX node in a totally new project, I get the same warning, plus a new error:

C:\Users\Dan\Documents\GitHub\HISE\hi_dsp_library\node_api\nodes\processors.h(1188,14): error C2039: 'handleModulation'
: is not a member of 'snex_node_impl::snex_node<1>' (compiling source file ..\..\Source\Main.cpp) [C:\Users\Dan\Desktop
\test\DspNetworks\Binaries\Builds\VisualStudio2022\test_DynamicLibrary.vcxproj]

[Dan Korneff]

@Christoph-Hart Anything else I can do ?

[Christoph Hart]

Can you send me the SNEX node code? This error shouldn't occur because it checks if you define that method in order to show a modulation source dragger.

[Dan Korneff]

@Christoph-Hart
I'm testing with simple "input * gain" code
Here's my project
https://www.filedump.us/s/WA99ns63mSeJKgg

template <int NV> struct gaintest
{
	SNEX_NODE(gaintest);

	double gain = 0.0;
	
	float getSample(float input)
	{
		return input * gain;
	}	
	
	
	
	// Initialise the processing specs here
	void prepare(PrepareSpecs ps)
	{
		
	}
	
	// Reset the processing pipeline here
	void reset()
	{
		
	}
	
	// Process the signal here
	template <typename ProcessDataType> void process(ProcessDataType& data)
	{
		for(auto ch: data)
		{
			for(auto& s: data.toChannelData(ch))
			{
				s = getSample(s);
			}
		}		
	}
	
	// Process the signal as frame here
	template <int C> void processFrame(span<float, C>& data)
	{
		for(auto& s: data)
					s = getSample(s);

	}
	
	// Process the MIDI events here
	void handleHiseEvent(HiseEvent& e)
	{
		
	}
	
	// Use this function to setup the external data
	void setExternalData(const ExternalData& d, int index)
	{
		
	}
	
	// Set the parameters here
	template <int P> void setParameter(double v)
	{
		gain = (double)v;
	}
};

@Christoph-Hart It seem that when you wrap a node, HISE adds a _pm. This is what's causing my newest crash. If I remove the phantom node, I can compile DSP. I slightly remember this happening in the past.

Not sure what's causing the error with previous projects yet.

[Dan Korneff]

@Christoph-Hart Are we not able to compile networks that contain compiled nodes? I thought we could before.

I'm getting these errors when I try to compile this test:

Yes wrapping/compiling a SNEX node directly causes adding the modulator.

But when SNEX and other nodes are combined into a chain node, then when that chain node is wrapped/compiled, it works.

By the way, as I see the bug in the snex_shaper node is fixed and it works.

yay!!

[Dan Korneff]

@Christoph-Hart I've narrowed it down to projects on my Network share.

Are the double \ \ something that could be causing this issue? Or do I need to look elsewhere

[Christoph Hart]

@Dan-Korneff Yes that looks a bit weird, but then the dll loader doesn't use anything else than the standard JUCE file classes so if you can load your project from that drive it should load the dll too. If you move it to a different drive, does it work?

[Dan Korneff]

@Christoph-Hart ok! Looks to be a bug with smb on my NAS. Files on my local disk work just fine.
After stripping/re-assigning permissions I'm back in action. So strange cause I could work on the network drive in HISE normally. Just couldn't export anything.
3 days down the drain...

Scratch that... still circling the drain
But at least I have an idea of what's up
