This Airwindows.h file is exactly the same as the one I'm using, so its not the problem I think.

Morphoice

@Lindon wicked. It does look like it's not a problem of the node but the network. If I disable the AllowCompilation in the Network Node properties the third party nodes do at least compile independent of that. So it might indeed throw a false positive on the polyphonic thing as Christoph suggested and therefor not properly build the DspNetworks.h

Christoph Hart

@Morphoice Yeah you're missing the node_properties.json file so the code generator doesn't know whether your C++ node should be polyphonic (as it should as your DECLARE_AIR_WINDOWS macro creates a class with a voice number template) so it makes an educated guess which appears to be wrong.

Whenever you paste in a ThirdParty code, always create the C++ template through the HISE menubar first, then replace the file content of the autogenerated file with your code. This ensures that it creates the proper flags in the node_properties.json file.

When you do so you should see something like this in ThirdParty/node_properties.json.

"Disintegrate": [
    "IsPolyphonic",
    "AllowPolyphonic"
  ]

Oh and yeah, use Git, then remove all the build files from the source control system, Dropbox is the complete wrong tool for the job.

Morphoice

@Christoph-Hart I will check that out. Thanks

Morphoice

@Christoph-Hart is there a list somewhere which folders/files exatcly to ignore in git?

@Morphoice

**/Binaries/

bueno! let's see how that goes.
atm HISE is complaining the source isnt the same commit hash as the build, although I just built it from the source.... narf

How many copies of HISE and the source code do you have?

Morphoice

@d-healey one. it'a a freshly installed pc, HISE has just been pulled from github and built

d.healey

@Morphoice Did you build the develop branch?

Morphoice

@d-healey yes sir

d.healey

@Morphoice In that case it could be just that Christoph hasn't updated the git hash so don't worry about it.

Morphoice

@d-healey well it does produce hundreds of compiler errors though ...

Christoph Hart

@d-healey if I forget to update the git it will not show this message, it just doesn‘t show the correct git in the about window.

That message means that there is a mismatch between the source code git hash and the compiled version.

Morphoice

@Christoph-Hart but how can I resolve this? I just compiled it again from the sourcecode and it still shows the message...

Christoph Hart

@Morphoice where does your HisePath setting point to?

Morphoice

@Christoph-Hart C:\HISE which is where github put the source... I'm just doing it again from scratch

d.healey

@Morphoice And when you run HISE you're running it from within that same folder?

Morphoice

@d-healey yes directly from the build directory.... I did it all over again, now github complains there is a filename too long when I try to clone my project onto the new pc.
I have to give up for the day, I need to go to work now. barkeeping. drinking. and vice versa.

Morphoice

@d-healey so the c++ error could be fixed thanks to christoph, there was actually a json file missing to hold some info about the third party node hence the DspNetworks.h was created wrongly...

as suggested by christoph to work with github rather than dropbox i managed to compile the the network on the pc, now attempting to compile the final plugin. fingers crossed, third day's the charm ;) (hopefully)
