Arch Linux User Repository

Sorry but the stuff you are discussing on GitHub is way over my head. I have only a very basic knowledge of C and C++. (◕‿◕)

I haven't used it yet :) I am fine to go with your recommendation. That said reducing the compilations/writes on RPi is best for its memory card?

Do you know what the problem with the cmake file is (applies to disctcc users)?

@bronze What would you prefer as a user? Just a single package for everything VC4 related or separating into 3 packages?

I also added the patch to vc4cl-git and added the 2 other packages as conflicts for now.

I also want to thank you because if it weren't for you and your communication with doe300 I would have never gotten myself to actually make the package work. So thanks!

Wow! It actually looks like I made separate packages for all the components but never finished them. They actually contain some of the same files so they conflict each other. (just a note for myself) 2 possible solutions:

1. Actually separate the packages (vc4c-git wouldn't contain anything from vc4clstdlib-git)
2. Just delete the 2 redundant packages and leave only vc4cl-git

Option 2 would be much simpler.

The patch works! Thx. Can you also apply the patch to package "vc4cl-git", file "vc4cl-git/src/VC4C-master/src/ProcessUtil.cpp"?

I now encountered a cmake error here (having to with a REGEX and bypassing distcc, it seems): https://github.com/doe300/VC4CL/issues/92#issuecomment-648276809

I don't know if this REGEX problem is an arch package problem.

I created a patch for what was suggested by doe300 on GitHub. I hope it works! I also added all the packages you mentioned as dependencies and build dependencies (I'm not sure what packages are required only for building the package so I took a guess).

The package installed after implementing the fix here: https://github.com/doe300/VC4C/issues/145#issuecomment-647030474

EDIT: I installed the following additional packages: "clinfo", "llvm", "opencl-headers" and "ocl-icd"

I have not made progress other than verifying that threads can be found (after creating a CMakeList.txt with "cmake_minimum_required (VERSION 2.8.7)" & "find_package(Threads)"):

Assuming that the problem must thus be elsewhere, I found a long list of dependencies for a Raspbian system:

sudo apt install build-essential git llvm clang clang-format libclang-dev libbsd0  libc6  libedit2  libffi6  libgcc1  libllvm  libncurses5  libstdc++6  libtinfo5 zlib1g llvm-dev ocl-icd-opencl-dev ocl-icd-dev opencl-headers clinfo

I may not have installed all dependencies partially because I don't know which are really needed or how they translate to Arch package names ...

I also added clang as a dependency

If you wish to modify the source code before building the package, you can do that with

git clone https://aur.archlinux.org/vc4c-git.git
cd vc4c-git
makepkg --nobuild -s
(this installs the dependencies, downloads and extracts the sources without building the package)
*make the changes*
makepkg --noextract -i
(this builds the package without replacing the source files and installs it after building it)
