Compiling Just an Empty Clone Container Fails

[clevername27]

@d-healey Did I answer your question about which versions well enough? I didn't mean to sound flippant—just that I really have tried them all (including the version you mentioned).

@d-healey said in Compiling Just an Empty Clone Container Fails:

/HISE/hi_dsp_library/node_api/nodes/Containers.h:116:49: error: ‘const struct scriptnode::wrap::clone_base<scriptnode::wrap::clone_data<scriptnode::container::chain<scriptnode::parameter::empty, scriptnode::wrap::fix<2, scriptnode::core::empty> >, 0, 1>, scriptnode::CloneProcessType::Copy>’ has no member named ‘isPolyphonic’
>   116 |     bool isPolyphonic() const { return get<0>().isPolyphonic(); }

I'm trying to parse this error. Basically, some code tried calling isPolyphonic() on a clone_base struct when isPolyphonic() is not defined for that struct. This is probably a runtime error only seen when compiling clone containers. The location of that code seems to be in the Containers.h file within the container_base struct.

The container_base struct has a protected member std::tuple<Processors...> called elements. This is relevant because the error is referring to get<0>().isPolyphonic() and get<0>() is defined further up in the Containers.h file
as (i'm not sure which one)

template <int arg> constexpr auto& get() noexcept { return std::get<arg>(elements).getObject(); }
template <int arg> constexpr const auto& get() const noexcept { return std::get<arg>(elements).getObject(); }

so get<0>().isPolyphonic() is kind of equivalent to std::get<0>(elements).getObject().isPolyphonic() which breaks down in English to get the first object in the elements tuple and ask if it's polyphonic. The error leads me to believe that there is a clone_base struct in that elements tuple of Processors and clone_base doesn't have function isPolyphonic().

clone_base is a struct defined in duplicate.h and does not seem to have a polyphonic anything related, so I'm guessing there shouldn't be a clone_base struct in that elements tuple. So I'm thinking where does it get in there? So I'm looking for where clone_base is referenced and I stumble on this alias definition in processors.h

template <typename T, int NumDuplicates>
using fix_clonecopy = clone_base<clone_data<T, options::no, NumDuplicates>, CloneProcessType::Copy>;

which means I can cut down the size of the error message to this

/HISE/hi_dsp_library/node_api/nodes/Containers.h:116:49: error: ‘const struct fix_clonecopy’ has no member named ‘isPolyphonic’
>   116 |     bool isPolyphonic() const { return get<0>().isPolyphonic(); }

I don't know how all this helps anyone. Does anyone else have a different error message related to this problem that I could look at to look for clues?

Im using

Im also doing this form a completely fresh, new and empty project...

I was only asking Lindon because he said it worked for him.

But you're using the snippet Bill posted?

@clevername27 I was curious about your issue here so I tinkered around with it, and I managed to get this to compile (based off of your example):

I couldn't make any sense of the debug console but it seems to me that the clone container is looking for the number of clones to be specified or it will fail to compile. I also had to add some type of processing in the container or else it would fail. I've used the clone container successfully in the past.

General rule of thumb I follow is make sure the NumClones is the first macro control (and the ranges match for each node it controls), and to precompile all of your processing in a separate scriptnode and load that into the clone container (less error prone, plus it keeps the network more organized).

@hujackus As @d-healey mentioned, we may be looking at different issues. That said, here are some links to error messages and possibly-useful information I've received in and around this issue. (@d-healey suggested running the compile directly from inside Xcode, which indeed provided more verbosity in error reporting.)

• Link 2

@HISEnberg Interesting and thank you - especially about the parameter ordering. I eventually stopped making the number of clones dynamic, and I think my snippets are all such—but maybe if I don't change the number of active clones during execution, the dynamic process is still happening - in which case, maybe it makes sense to always set the number of clones, manually?

I also don't think any of us have stopped to realise the moral and ethical implications of cloning, but I guess one thing at a time.

[clevername27]

@hujackus I am feeling like a proper lazy slug looking at all the sleuthing you're doing. (I'm taking a look, now.)

And…you may be on to something. I tried compiling my snippet with that function always returning TRUE, and it compiled.

When you say struct, do you mean class? (Structs don't have methods, although I guess you could use a function pointer.)

I'm assuming that the function is returning whether Clone nodes can be used in polyphonic networks. So, I changed the return value from FALSE to TRUE. Seems to work. Cheers for your detective work, @hujackus.

Update: Didn't work for my original snippet.

@d-healey If this works for others, do you want to submit this?

Yes

They can in C++ and do in the HISE codebase.

[clevername27]

@d-healey You're absolutely right.

Yeah clone_base is a struct. It has a few methods, but no member named ‘isPolyphonic’. I'm assuming there is a wrapper class somewhere trying to cast a clone_base into a class that has a isPolyphonic() function.

Setting the default return value of NodeBase::isPolyphonic() from false to true is an interesting lead. Looking for subclasses of NodeBase now to see how it relates to the clone_base struct.
