Cannot build: camera_device_open() - too many arguments

[edoardogiacomello]

Hello,
I'm trying to build icamerasrc to make the webcam of my Lenovo X1 Carbon (gen 10) work in Ubuntu 22.04.
I've installed all the other dependencies listed in the instructions with no errors (using ipu6ep), however then when i run
make -j8 the build fails with this error:

gstcamerasrc.cpp: In function ‘gboolean gst_camerasrc_start(GstCamBaseSrc*)’:
gstcamerasrc.cpp:2839:27: error: too many arguments to function ‘int icamera::camera_device_open(int)’

Am I doing something wrong or is it just a bug?

Thanks,
E.

I have this too on archlinux -- attempting to install gives me the exact same output as above.

For the engineering-team to have a chance to look into this, can you provide as many information, please?
Which versions (name, branch, repo, commit) of which components of icamerasrc and its dependencies do you have installed (and how)?
How does your environment (HW and SW) look like?
How have you set-up your build environment, compiling "natively" or e.g. within a Docker container (or virtual-env)?
Any local changes to source-code?
Is this the first time you tried to build - or have you seen it building successfully using an older version or other HW?

I changed the line that is mentioned in the output of make to

//ret = camera_device_open(camerasrc->device_id, camerasrc->num_vc);
    ret = camera_device_open(camerasrc->device_id);

It then was able to compile, but I'm unsure if this will break something else further down the line.

Also it still doesn't work for me, because when running sudo -E gst-launch-1.0 icamerasrc buffer-count=7 ! video/x-raw,format=YUY2,width=1280,height=720 ! videoconvert ! ximagesink I get this output:

WARNING: erroneous pipeline: no element "icamerasrc"

I'm not sure what is going wrong here, but according to https://aur.archlinux.org/packages/icamerasrc-git I'm not alone with the problem.

I'm unsure on how to proceed, since I'm new to this type of scenario.

But generally I followed the guides of the ipu6 projects in order and everything worked up to the point of trying to compile this plugin.

@HackXIt do you respond to @edoardogiacomello ?

In this case the IPU-camera-HAL version doesn't match to the used version of icamerasrc.

(Optional) Support for e.g. virtual-channels was considered in IPU6-Camera-HAL branch "iotg_ipu6", see e.g. here: "https://github.com/intel/ipu6-camera-hal/blob/iotg_ipu6/include/api/ICamera.h#L237".

Unfortunately I don't see a public documentation of what dependency in which version/branch/commit/release to use.

[edoardogiacomello]

Which versions (name, branch, repo, commit) of which components of icamerasrc and its dependencies do you have installed (and how)?

1. ipu6-drivers - dfedab0

I followed instructions for point 3 (Build with DKMS)

2. ipu6-camera-bins - 276859f

I set IPU_VER=ipu6ep and followed the instructions under "Deployment"

3. ipu6-camera-hal - 884b81a

I followed the instructions without errors, then rebooted

4. icamerasrc - 82cb8fc

I'm trying to follow build instructions but the make command fails. I've tried with older releases with different errors.

How does your environment (HW and SW) look like?

My HW is a Lenovo X1 Carbon (gen 10), running Ubuntu 22.04.

How have you set-up your build environment, compiling "natively" or e.g. within a Docker container (or virtual-env)?

I'm compiling natively.

Any local changes to source-code?

None

Is this the first time you tried to build - or have you seen it building successfully using an older version or other HW?

I've tried a couple of months ago without success, then cleaned everything and I'm retrying now based on the success from https://askubuntu.com/a/1461869
The webcam is working properly on Windows 10 which is installed alongside Ubuntu.

In this case the IPU-camera-HAL version doesn't match to the used version of icamerasrc.
(Optional) Support for e.g. virtual-channels was considered in IPU6-Camera-HAL branch "iotg_ipu6", see e.g. here: "https://github.com/intel/ipu6-camera-hal/blob/iotg_ipu6/include/api/ICamera.h#L237".
Unfortunately I don't see a public documentation of what dependency in which version/branch/commit/release to use.

I'll attempt to recompile using your suggested branch, maybe it will work.

But having read a bit more into it, it currently seems like, that the driver is still in active development and the problem with the MIPI driver is common to the users with those cameras on linux.
I was trying to jump ahead (instead of waiting for the driver being generally distributed), by compiling the available driver as described in the repositories by myself.

@HackXIt do you respond to @edoardogiacomello ?

I thought if I add to this existing issue, that I'm having the same problem, it would help.
In general, I only recently changed to Linux, so I'm not that well versed. I'm sorry, if it didn't provide more insight or information.

The internal refactoring as documented in the discussion at #31 (comment) still appears to be going on: The suggestion to checkout the tag 20230307_0904_rpl_plat does not result in this error to go away.

Did anyone have success in compiling icamerasrc against the current other ipu6 projects?

---

The tag that is suggested has the same syntax of the method call which causes the error as described in #32:

icamerasrc/src/gstcamerasrc.cpp

Line 2840 in 17841ab

ret = camera_device_open(camerasrc->device_id, camerasrc->num_vc);

As per the blame, this line is three years old

and also calls its alternative with less arguments, in case no virtual channels are to be stripped. Its configuration is disabled, yet the if is evaluated for the first case.

$ grep -A 1 STRIP_VIRTUAL_CHANNEL_CAMHAL config.log
configure:17570: checking check if STRIP_VIRTUAL_CHANNEL_CAMHAL is ON
configure:17577: result: no
--
USE_STRIP_VIRTUAL_CHANNEL_CAMHAL_FALSE=''
USE_STRIP_VIRTUAL_CHANNEL_CAMHAL_TRUE='#'

https://github.com/intel/icamerasrc/releases/tag/20230307_0904_rpl_plat has a different README than the branch https://github.com/intel/icamerasrc/tree/icamerasrc_slim_api, which does not mention export STRIP_VIRTUAL_CHANNEL_CAMHAL=ON anymore.

Checking out that tag and providing the additional export rule results in a successful build here.

Also everything below the comment in #28 (comment) helped, plus the runcamera.sh script from https://askubuntu.com/a/1461869
