SampleMaps are not seen and not saved with project.

[d.healey]

I can see two issues with your sample map.

• It needs to have a .xml file extension - this isn't added automatically by HISE on Linux for some reason.
• Your samples need to be in your project's Samples folder.

@d-healey thank you, I'll try it out in the evening

[Levitanus]

So I've compiled a debug version of HISE, saved a new samplemap from it with Project_Folder paths. And still makes no sense. After saving a new samplemap, it removes samples from sampler. And throws 2 errors:

@Levitanus did you compile with gcc14?

[Levitanus]

@d-healey yes, with gcc14 with 01 optimizations. I ran the 11th installation again this morning before going out to work, but in an hour it was not yet installed. Hope, that it succeed wile I'm out)

[Levitanus]

How is about clang? Makes it sense trying to build it with clang (LLWM)? And general possibility? I found no signs of compiler in make file, but I'm very unfamiliar with make…

[d.healey]

I've only worked with GCC on Linux so not sure about setting up clang. Gcc14 could be the cause of your issue.

[Levitanus]

Finally, i succeeded to install gcc11, and the result is the same…

[d.healey]

@Levitanus said in SampleMaps are not seen and not saved with project.:

the result is the same…

Can you make a minimal project that has the issue and send it to me?

[Levitanus]

I also feel, that with the last added sampler, it started to behave very strange. For example, it didn't receive MIDI-signals. But in 1–2 attempts, the samplers started to work normal. Before I started to convert samplemaps.

I would say, it's any project in my case…
test.zip

[d.healey]

@Levitanus When I load your project I see the sample map available in the dropdown. Also I recommend saving your project as an xml rather than a .hip if you're not already.

[Levitanus]

@d-healey Yes, that's the issue, I don't…
I've just tried with your last development commit, and still does not work, also tried to clear all possible hise resources in home folder.

[d.healey]

@Levitanus Must be something specific to your OS. Do you have a virtual machine where you can try a different distro?

[Levitanus]

So, the reason was, that I selected expansion type as full. I'm not sure, what expansions are in general, but it blocked any samplemaps from working.

[d.healey]

@Levitanus Ah that makes sense. Expansions are a system for adding additional content (sample maps, samples, presets) to a plugin.
