Compiling C++ nodes and Scriptnode Networks

HISEnberg

@Christoph-Hart I opened a Github Issue about this but is there anyway to change the FX compiler to automatically compile C++ nodes first, and then Scriptnode networks?

Currently, whenever I go to compile my fx again, I have to turn off the compilation on the Scriptnode networks, compile the C++ and wait for the compiler to finish. Then I need to go back into the networks, set them to compile and go through the whole process again.

DanH

@HISEnberg yeah I've found this too. There was one network that seemed buggy, and when I figured out which one it was I rebuilt it and it's been ok ever since.

Christoph Hart

Can you make a example project that requires this? Usually if you trash the dll before rebuilding it should always work - if a scriptnode network requires a C++ node that isn't compiled yet it will use a placeholder during the compilation process, but if there is an old DLL hanging around, this might cause issues.

TLDR: Does the problem persist if you delete the entire DspNetwork/Binaries folder before a clean rebuild?

DanH

@Christoph-Hart I still have the network and probably a time machine backup of the whole project before I rebuilt that network so will try and cobble something together. Pretty certain I deleted either the dll or the whole binaries folder but will try with and without.

Perhaps a good idea to auto move the dll during the compile process and then put back if it fails?

@Christoph-Hart

I tried deleting the Binaries folder before rebuilding on my Windows machine and I get errors like the following:

Just to reiterate, it will work fine if I compile the C++ node first, then compile the C++ node and the Scriptnode network.
This is an example, it is literally just the autogenerated C++ template embedded into a Scriptnode Network.

@HISEnberg have you setup the node_properties.json correctly? Looks like it can't deduce whether the uncompiled nodes are polyphonic.

HISEnberg

@Christoph-Hart Thanks for clarifying, that was my mistake. So deleting the Binaries does indeed work!!!
