Default Value of a Slider doesn't change and the Slider Value always jumps to zero

[d.healey]

@Myroslav-Artiukh Working fine here, are you using the develop branch?

[Myroslav Artiukh]

@d-healey I just built HISE yesterday by following one of your tutorials and the manual, so it's definitely the newest version from github, I'm not sure if it's the develop branch or not.

[d.healey]

@Myroslav-Artiukh Check which branch you built (although you shouldn't have this problem with any branch)

[Myroslav Artiukh]

@d-healey I just cloned this repository: https://github.com/christophhart/HISE

[d.healey]

@Myroslav-Artiukh git checkout develop to move to the latest branch

[Myroslav Artiukh]

@d-healey I got this error:
error: Your local changes to the following files would be overwritten by checkout:
projects/standalone/JuceLibraryCode/JuceHeader.h
Please commit your changes or stash them before you switch branches.
Aborting

[d.healey]

@Myroslav-Artiukh It's not an error, it's just telling you that your changes will be overwritten because you haven't commited them. If you want to keep them you can use git stash, otherwise just run git reset --hard before switching branch

[Myroslav Artiukh]

@d-healey It worked. Should I build HISE again?

[d.healey]

@Myroslav-Artiukh Yes

[Myroslav Artiukh]

@d-healey The build just finished and the problem is still there. I got a lot of warnings when building, for example this:

../../../../JUCE/modules/juce_core/text/juce_String.cpp:164:52: warning: ‘operator delete []’ called on unallocated object ‘emptyString’ [-Wfree-nonheap-object]
  164 |                 delete[] reinterpret_cast<char*> (b);
      |                                                    ^
../../../../JUCE/modules/juce_core/text/juce_String.cpp: In function ‘getWithParameters.isra’:
../../../../JUCE/modules/juce_core/text/juce_String.cpp:56: note: declared here
   56 | static const EmptyString emptyString { 0x3fffffff, sizeof (String::CharPointerType::CharType), 0 };
      | 

Maybe I need to update the JUCE version as a lot of these warnings have to do with JUCE?

I also don't use the Intel IPP, maybe I need to turn it off somewhere in the settings?

[d.healey]

@Myroslav-Artiukh You can ignore those warnings, you don't need to install JUCE everything you need is included with HISE.

Which version of Ubuntu are you using?

Does changing the default value to something other than 0 make a difference?

[Myroslav Artiukh]

@d-healey I am using the newest version of Ubuntu (24.04 I think), Ubuntu Studio to be exact.

I can't change the default value to anything other than 0, which is why I thought that it might be the reason this is happening.

[d.healey]

@Myroslav-Artiukh said in Default Value of a Slider doesn't change and the Slider Value always jumps to zero:

I can't change the default value to anything other than 0,

That's strange, you should just be able to enter a new value in the interface designer.

[Myroslav Artiukh]

@d-healey Could you maybe send me your build of HISE for Ubuntu (if you are allowed to do that). Maybe I have done something wrong during the build and that's why it doesn't work.

[d.healey]

@Myroslav-Artiukh I don't use Ubuntu - however I'm installing it now to test

[Myroslav Artiukh]

@d-healey Thank you so much

[d.healey]

@Myroslav-Artiukh I can't even get HISE to compile, I get errors about missing header files - did you run into these?

[Myroslav Artiukh]

@d-healey I don't think so. What exactly is missing?

Some dependencies are hard to find and I had a few other issues, which were not hard to solve, but I don't remember any headers missing.

[d.healey]

@Myroslav-Artiukh

It's saying it can't find gtk.h or ft2build.h

Also
Package 'webkit2gtk-4.0', required by 'virtual:world', not found

Apparently webkit2gtk-4.0 isn't available on the latest version of Ubuntu.

[Myroslav Artiukh]

@d-healey You can get webkit2gtk-4.0 installed by copying files from some websites, but go into the Projucer and uncheck the "Use Web Browser" box in the juce_ui_extra module (not sure if the names are 100% right, but it should be something similar).

webkit2gtk-4.0 is only needed for web applications.
