Error while building intel-ipu6ep-camera-hal-git (Dell XPS 13 9315)

I have the same problem with the current main branch and an up-to-date Arch Linux:

==> Starting build()...
CMake Deprecation Warning at CMakeLists.txt:17 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

I have the same error but on the icamerasrc installation.

[kotturi-mahipal]

Hope someone solves this quickly.

Same problem on Arch Linux

Hello. I stumbled upon this issue too, on both intel-ipu6ep-camera-hal-git and icamerasrc.
This kind of dirty hotfix allowed me to go through the install:

• for intel-ipu6ep-camera-hal-git, edit intel-ipu6ep-camera-hal-git/PKGBUILD and add the following method:

prepare() {
    cd $_pkgname
    sed -i "s|-D_FORTIFY_SOURCE=2| |" CMakeLists.txt
}

then replay install.sh

• for imcamerasrc, the trick is similar but on different files, and since the AUR package is directly used, you have to call your package manager with relevant options to allow editing the PKGBUILD during install. For me it was:
  • yay -S --editmenu icamerasrc
  • then add a similar method in PKGBUILD:

prepare() {
    cd $_pkgname
    sed -i "s|-D_FORTIFY_SOURCE=2| |" src/Makefile.am
    sed -i "s|-D_FORTIFY_SOURCE=2| |" src/interfaces/Makefile.am
}

From there you can again replay install.sh which should finish installing missing packages.

For the record, despite the hotfix I mentioned above, I struggled like hell to make my webcam work after an upgrade (v4l2-relayd crashing systematically on stream start). I eventually narrowed down the issue to icamera-src current version, and circumvented it by targeting the same version as the icamerasrc-git.old still present in the repository. I plan to check whether this issue has been identified upstream, and if not, open the corresponding issue

EDIT: opened an issue in corresponding repository to discuss this

[Milihhard]

Thanks for the information!. Cleaning the repository and the package manager, then switching to the old fix for icamerasrc seems to work.

[ragu-manjegowda]

Thank you! Switching to old fix for icamerasrc worked for me as well.

If anyone needs exact steps,

• Open install.sh and change icamerasrc-git to icamerasrc-git-fix.old
• Follow this instruction to get around compilation errors
  • for intel-ipu6ep-camera-hal-git, edit intel-ipu6ep-camera-hal-git/PKGBUILD and add the following method:

    prepare() {
        cd $_pkgname
        sed -i "s|-D_FORTIFY_SOURCE=2| |" CMakeLists.txt
    }
    

  • for icamerasrc-git-fix.old, edit icamerasrc-git-fix.old/PKGBUILD and add the following method:

    prepare() {
        cd $_pkgname
        sed -i "s|-D_FORTIFY_SOURCE=2| |" src/Makefile.am
        sed -i "s|-D_FORTIFY_SOURCE=2| |" src/interfaces/Makefile.am
    }
    

• Make sure to uninstall icamerasrc-git if you previously installed with workaround. Also, ensure clean build by manually deleting cache or using appropriate build arg like --rebuild=yes (for paru)

[kotturi-mahipal]

Thank you! Switching to old fix for icamerasrc worked for me as well.

If anyone needs exact steps,

* Open `install.sh` and change `icamerasrc-git` to `icamerasrc-git-fix.old`

* Follow [this instruction](https://github.com/stefanpartheym/archlinux-ipu6-webcam/issues/77#issuecomment-2029508628) to get around compilation errors
  
  * for intel-ipu6ep-camera-hal-git, edit intel-ipu6ep-camera-hal-git/PKGBUILD and add the following method:
    ```
    prepare() {
        cd $_pkgname
        sed -i "s|-D_FORTIFY_SOURCE=2| |" CMakeLists.txt
    }
    ```
  * for icamerasrc-git-fix.old, edit icamerasrc-git-fix.old/PKGBUILD and add the following method:
    ```
    prepare() {
        cd $_pkgname
        sed -i "s|-D_FORTIFY_SOURCE=2| |" src/Makefile.am
        sed -i "s|-D_FORTIFY_SOURCE=2| |" src/interfaces/Makefile.am
    }
    ```

* Make sure to uninstall `icamerasrc-git` if you previously installed with workaround. Also, ensure clean build by manually deleting cache or using appropriate build arg like `--rebuild=yes` (for paru)

Newbie here. Where should put the prepare() block in the PKGBUILD?

I needed to pin some package versions, in addition to following the steps @kotturi-mahipal outlined. More details in #79.

I did exactly as you mentioned, but the compilation fails in my case:

Any idea, what I can do?

Could you be missing libdrm on your system ?

[elhossary]

No, It is installed already, I reinstalled it and still get that error

[danielksato]

@elhossary I ran into the same issue. It was introduced in a new release of the intel-ipu6ep-hal package on 4/9.

I was able to make it compile by modifying the source to point to libdrm/i915_drm.h instead of drm/i915_drm.h - I suspect this might be a distro-specific issue; it could be fixed in the PKGBUILD.

HOWEVER, even though it compiled, that built version didn't work.

I resolved the problem by pointing the PKGBUILD to a specific commit as described in #79.

[elhossary]

@danielksato, Thank you for the clarification
