faust2daisy generated code does not compile for -pod or -patch option

When compiling code using faust2daisy with option -pod or -patch the code does not compile. Only -patchsm is working.

The problem is that somehow ValueConverter.h is not included in the generated cpp file.

Steps for reproduction

Versions Used:

• Faust master-dev, 2.76.0, Commit: 5ed7170
• libDaisy v7.1.0

Daisy Toolchain Setup on Linux:

1. Create a folder, e.g.

   $ mkdir ~/daisy

2. Get arm-none-eabi:

   • See DaisyWiki

3. Get libDaisy:

   $ git clone --recurse-submodules https://github.com/electro-smith/libDaisy

4. Create environment.rc file with the following content:

   export LIBDAISY_DIR=~/daisy/libDaisy
   
   GCC_PATH=~/daisy/gcc-arm-none-eabi-10-2020-q4-major/bin
   export PATH=$GCC_PATH:$PATH

5. Compile libDaisy:

   $ source environment.rc
   $ cd libDaisy
   $ make

Compilation:

1. dsp file minimal_example.dsp

   
   import("stdfaust.lib");
   declare name "Daisy Seed Bug";
   declare options "[midi:on]";

gate = button("gate"); vel = hslider("gain", 0, 0, 1, .01); freq = hslider("freq", 440, 0, 20000, 0.01);

process = os.triangle(freq) vel : _en.adsr(.1,.1,.7,.2, gate) <: ,;

2. Generated cpp code with:
```bash
$ faust2daisy -patch -midi -sr 48000 -bs 32 -uim -source minimal_example.dsp

when running make within the generated folder

$ cd minimal_example
$ make

a lot of the compilation errors appear, since ValueConverter.h is not included:

In this part of the daisy architecture (ex_faust.cpp) the corresponding gui source files are included.

#include "faust/gui/meta.h"
#include "faust/gui/UI.h"
#if defined PATCHSM
#include "faust/gui/DaisyPatchInitControlUI.h"
#else
#include "faust/gui/DaisyControlUI.h"
#endif
#include "faust/dsp/dsp.h"

ValueConverter.h is included in DaisyControlUI.h and DaisyPatchInitControlUI.h I don't understand why the ValueConverter.h gets included for DaisyPatchInitControlUI.h only.

[sletz]

Well DaisyPatchInitControlUI was developed after DaisyControlUI with an external contribution, and looking at the file, a lot of code is actually duplicated. So I guess the proper way would be to rework all of that, and put the new code of DaisyPatchInitControlUI in DaisyControlUI to finally keep a unique DaisyControlUI file, and possibly use #if defined PATCHSM ....some code... #endif inside it.

But this means a bit of work ((-;

hmmm... unfortunately I don't have this hardware to verify that stuff finally, since I've built my own hw interface for the raw daisy seed board. I could do it in blind mode without testing on the patch / pod only but thats not that good idea I think.

[ghoppla]

Despite the fact that the code is duplicated, from the preprocessor logic the the weird thing is that ValueConverter.h is not included for the -pod and -patch Option. Don't get it why...

. I could do it in blind mode without testing on the patch / pod only but thats not that good idea I think.

But you could at least test if the restructured code would compile right ?

lol... you owned me. Okay, I do my best, but it may need some days till I find the time. I hope someone can then test the code on hardware.
