I'm using Plugdata in compile mode, so expr~ isn't available.

If you are on the latest toolchain release it is (mostly) available!

In the next release of plugdata (or the current nightly build) the warnings for expr/expr~ will be gone as well, but the toolchain will already work. So just ignore the warnings for now

I think you should just be able to put Gem in the list of libraries in Startup in the Preferences.

One issue however is that GEM requires OpenGL, where the Raspberry Pi (and other ARM based devices) only have OpenGLES.

I have had some moderate success using GL4ES to translate this: https://github.com/ptitSeb/gl4es

Use [block~ 1] in a subpatch or abstraction and everything inside there will run single sample.

You can also use [fexpr~] to run mathematical expressions on specific samples in a block.

Exporting code using the Heavy Compiler will run single sample by default.

I was talking about plugdata

You should be able to run LTS binaries on 25.10 - Actually any Linux binary built with an older libc will probably work on a newer system.

@jameslo A lot of the objects you are using are not supported by the Heavy Compiler -> https://wasted-audio.github.io/hvcc/docs/09.supported_vanilla_objects.html

We have added expr and expr~ support this month and it should come to the plugdata toolchain shortly!

@donnerbono Latest HVCC now supports expr and expr~!

You will have to put 0.5 instead of .5 though

Some other limitations also apply: https://wasted-audio.github.io/hvcc/docs/02.getting_started.html#known-limitations

Clearly you need some header files. On debian based systems alsa/asoundlib.h comes from libasound2-dev

You need to install all the build requirements on your machine first ..
