Hi!

I did build the webOS for qemux86, Raspberry Pi3, 4 and then install pip using curl to download that can install pip for python.

And I wrote 'pip install opencv-python' to terminal, so successfully install the 'opencv-python' but I can't 'import cv2' because webOS OSE don't have 'libSM.so.6' library.  
I want to import cv2 using libSM.so.6 library

If i want to use libSM.so.6 on webOS, I think need to build the libSM.so.6 library together via yocto. But I don't know how. What should I do?

plz help me.. T.T

u can see below the error messege  
"ImportError: libSM.so.6: cannot open shared object file: No such file or directory"

information :  
hardware : raspberryPi 4 (4GB)

Hi,

If you have source code to build libSM.so.6, you can build it using toolchain that comes from webOS NDK ([https://www.webosose.org/docs/guides/setup/native-development-kit-setup/](https://www.webosose.org/docs/guides/setup/native-development-kit-setup/)).

than you can move that shared library to the suitable location such as /usr/lib.  
But, I can't give a definite answer because I didn't try that.

Instead of building a libSM library, I try to build OpenCV using yocto. If I will find a proper solution to use OpenCV, I will share how to you.

As far as I know, webOS OSE already has an oepnCV recipe. So, I tried to build an openCV component, but I met an error and didn't solve it.

build-webos$bitbake opencv

If I will be successful in building an openCV, I will let you know.

@SSo Could you try to build an OpenCV in your build environment?

Hi,

I'm compiling openCV for raspberry Pi4. I'll leave a comment when the result comes out.

It looks successfully to build an openCV for RPI3. Then you can move the IPK file to RPI3(webOS OSE 1.x) and try to install it using opkg command.

Today I reset Ubuntu of my laptop from 14.04 to 18.04. and I will try to build OpenCV for RPI4.

Yes, but I don't know which of the ipk files on BULD/deploy/ipk/raspberrypi4/ are required for installation. and what method to use to share the ipk file for you?

If you reply to this, I'll share the build ipk file to you.

I also succeeded to build the image. So, I have same thing that you have. But, I don't have any idea which IPKs are useful for using the openCV. If i may find, will share with you.

You can add opencv when building webos-image. Then all libraries will be added after making image,

Before running "bitbake webos-image", you need to add opencv into WEBOS\_FOSS\_MISSING\_FROM\_RDEPENDS of "/build-webos/meta-webosose/meta-webos/recipes-core/packagegroups/packagegroup-webos-extended.bb" file.

```
WEBOS_FOSS_MISSING_FROM_RDEPENDS = " \
    bzip2 \
    curl \
    e2fsprogs \
    hunspell \
    icu \
    iproute2 \
    lsb \
    makedevs \
    ncurses \
    openssl \
    procps \
    psmisc \
    sqlite3 \
    opencv \
    ${@oe.utils.conditional('VIRTUAL-RUNTIME_init_manager', 'systemd', 'systemd-analyze', 'sysvinit-pidof', d)} \
```

After creating an image including the openCV, you can use the openCV on python code. But you MUST use 'python3.5' command instead of 'python' command. (As far as I know, default python command of webOS OSE 2.X is based on 2.7.16.

Python 3.5
