[packaging] libclc-20-dev from apt.llvm.org doesn't ship clcfunc.h

[TheRealCuran]

Trying to use rusticl from Mesa is, at the moment, not fully possible, since libclc-20-dev from apt.llvm.org is missing clcfunc.h (libclc/clc/include/clc/clcfunc.h).

Currently the following files are installed to /usr/include/clc by libclc-20-dev

when I try running clinfo.

[TheRealCuran]

@EugeneZelenko the platform is very wrong, please make it platform:linux (or platform:debian if you have that)

[EugeneZelenko]

Sorry for mistake.

[TheRealCuran]

No problem; thanks for doing this kind of work! (Maybe look at the mrlabel-maker bot Mesa/Freedesktop is using? They just have a configuration file to do automatic labelling (for most cases).)

[EugeneZelenko]

There are some trivial automation already, but it's far from being perfect and extensive :-(

By the word, using LLMs for deducing labels from crash call stacks would be great...

[TheRealCuran]

OK, I followed this rabbit hole a bit more and I can only say: you are not installing the headers for libclc-20-dev properly at all. Besides the clcfunc.h you are also missing (at the very least):

• clctypes.h
• math/gentype.inc
• math/unary_decl.inc
• integer/gentype.inc
• relational/floatn.inc
• relational/unary_decl.inc
• relational/binary_decl.inc

Long story short: please ship everything in libclc/clc/include in your development packages.

(To be honest: I am surprised this is not the case yet!)
