SOULPatchHostDemo

Lucretio · March 6, 2021, 9:45am

Good morning and first of all thanks a lot for SOUL. I love it and I think that for musician like me who have a less technical computer science knowledge is a bless.
I have a problem running the SOULPatchDemoHost and I apologise for this being a silly question, but it is really stopping me.
I am on MacOSX Catalina and I am using Xcode. when I open the SOULPatchHostDemo it tells me that “I need to put the DLL or symlink next to this executable”.
how do I get this file? is it the .soulpatch file?
and by “next to this executable”, does it means in the build folder?

also, another silly question but that would really helpful for me. how do I edit the GUI of the soultatch from JUCE.

thanks again, love and respect.

Thanks!

You can get the DLL from the releases:

This is the hook for adding a JUCE GUI:

thanks a lot @jules ! I was a little bit lost and big up for the great work. I really believe audio programming was missing SOUL

I am sorry to be pedant about this but maybe the solution to my problem could be helpful for somebody else.
when I build and run the SOULPatchHostDemo App on XCode 12 on MacOS Catalina I got the message:
Failed to correctly load the patch DLL at "/mylibrarylocation/SOUL_PatchLoader.dylib

and in the XCode console I get:

JUCE v6.0.4

I can’t understand what I am doing wrong

Hi Lucretio and Jules.

I’ve been struggling with the same issue (or a very similar one) for the last few hours.

Before, the error was “Can’t find the SOUL patch DLL! …”.
After placing the binary next to the executable now the error I get is “Failed to load the patch DLL at …[patch location]”.

My console shows the following:
JUCE v6.0.7

I can’t wait to start learning SOUL and then coding a UI in React after this newbie issues get sorted out.

Regards,

Pere

Well, it’s either looking in the wrong location, or you’ve got a version of the DLL that doesn’t match the version of the source code you’re using. Just step into the debugger when it tries to load the library and you should see how far it gets and what happens.

Lucretio · March 7, 2021, 3:24pm

the location is alright, I tried using earlier versions of the library but no success

jules · March 7, 2021, 7:43pm

And assuming you followed my advice to step into it with the debugger and see how far it gets, what did you see?

ToxVox · March 7, 2021, 8:03pm

Same here. Seems as if the problem occurs when initializing the library.

bool initialisedSuccessfully() const
{
return library->library != nullptr;
}

My Setup:

MacOS 11.2.2
Xcode
JUCE 6.0.7
SOUL 1.0.82

jules · March 7, 2021, 8:12pm

Well, sure, that code is checking whether it worked, but you’re only going to learn what’s wrong if you step through the bit where it actually tries to open the library, which is in the SOULPatchLibrary constructor:

    SOULPatchLibrary (const char* soulPatchLibraryPath)
        : handle (openLibrary (soulPatchLibraryPath))
    {
        if (handle != nullptr)
            if (auto getVersionFn = (GetLibraryVersionFunction) getFunction (handle, "getSOULPatchLibraryVersion"))
                if (isCompatibleLibraryVersion (getVersionFn()))
                    createInstanceFunction = (CreateInstanceFunction) getFunction (handle, "createSOULPatchBundle");
    }

where you can see it getting the version and checking. My guess is that you’re just not using a matching version of the DLL and the code, but if it doesn’t even manage to find the entry-point function then it could be the wrong type of DLL (e.g. ARM vs Intel?) or something else.

Lucretio · March 7, 2021, 10:06pm

finally I got that

I had an older version of the library. now it is working and the fun can begin.
sorry but I was not so good with the Xcode debuger and he took me a while.
thanks a lot

ToxVox · March 7, 2021, 10:27pm

My git clone version from yesterday still doesn’t work. But with the download version it works…
Anyway the soulful games can begin!
Thanks

Great, hope you all build some cool stuff with it
