Arch Linux User Repository

I got around the error below by disabling distcc in /etc/makepkg.conf

The next (and final?) error, I get:

Due to https://github.com/doe300/VC4C/commit/1bb1b55b78cb52ac0bf85d1caf0e87ea0ea8a531 I modified the cmake line in the PKGBUILD and added 'VC4CL_STDLIB_PRECOMPILE':

cmake "$srcdir/VC4C" -DCMAKE_BUILD_TYPE=Release -DMULTI_THREADED=true -DCLANG_FOUND=/usr/bin/clang -DVC4CL_STDLIB_DIR=/usr/local/include/vc4cl-stdlib -DVC4CL_STDLIB_PRECOMPILE=OFF -Wno-dev

I also changed the dependency on ocl-icd to khronos-ocl-icd. This is an experiment.

I got here, before I hit a familiar error:

Seems at this part in the process CLANG_FOUND=/usr/bin/clang is ignored?

@satcom886 If they don't have any releases tags then the example labeled:

If there are no tags then use number of revisions since beginning of the history

should be used

@katt Oops! Sorry. I only added pkgver() to one of the packages.

Also, what pkgver should I choose if the upstream doesn't have any releases/tags?

Please take a look at https://wiki.archlinux.org/index.php/VCS_package_guidelines#The_pkgver()_function and adjust your PKGBUILD accordingly. Applies to your your other packages as well.

I think I separated the packages without completely breaking something.

Ok, it should be fixed now.

I'm a little busy these days, but I should have time tomorrow. I'll add the clang path and vc4clstdlib path into the PKGBUILD. I think $srcdir/VC4CLStdLib-master/include should work, but we'll see.

I managed to build and install the package (seemingly error-free). I had to set:

-DCLANG_FOUND=/usr/bin/clang

(needed in case you run distcc)

and

-DVC4CL_STDLIB_DIR=<full-path>/vc4c-git/src/VC4CLStdLib-master/include

(needed because the CMakeFile.txt uses a relative path that doesn't exist)

However, "sudo clinfo" doesn't give the desired result, so some more work to do?

This (https://github.com/doe300/VC4CL/issues/92#issuecomment-649199654) may be a problem in the PKGBUILD file, due to merging the 3 packages? Cannot find VC4CLStdLib.h

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)

Should clang be listed as optional dependency? I noticed some complaints when I tried to build the package. Also, I submitted "https://github.com/doe300/VC4C/issues/145" but it may be an arch issue. I cannot or failed to perform doe300's suggestion. Tips?
