Error occurs when adding libmodbus to st-image-weston

I have successfully build st-image-weston using Distribution-Package.

Now I want to add libmodbus to st-image-weston.

I refer to the wiki page below.

https://wiki.st.com/stm32mpu/wiki/How_to_integrate_an_external_software_package

​

1)​

​I checked the libmodbus recipe in the path below.

And I am using the meta-oe layer containing libmodbus.

But I can't find libmodbus in the target.

Why doesn't rootfs include libmodbus?

layers/meta-openembedded/meta-oe/recipes-extended/libmodbus

2)

I tried to add libmodbus by executing the command below.

The following error occurs.

how to fix it?

echo 'IMAGE_INSTALL_append += "libmodbus"' >> ../layers/meta-st/meta-st-openstlinux/recipes-st/images/st-image-weston.bbappend
bitbake st-image-weston -c cleanall
bitbake st-image-weston

    Hi again @hochul yoo​ 

    I am looking at your next question "how to fix it?" (build problem with libmodbus).

    I performed the following commands:

    $ bitbake st-image-weston
$ echo 'IMAGE_INSTALL_append += "libmodbus"' >> ../layers/meta-st/meta-st-openstlinux/recipes-st/images/st-image-weston.bbappend
$ bitbake st-image-weston -c cleanall
$ bitbake st-image-weston

    But I was not able to reproduce your error.

    Could you make a new attempt with the following commands please?

    $ bitbake -c cleansstate xz-native
$ bitbake -c cleansstate libmodbus
$ bitbake st-image-weston

    I guess there are some troubles with the bitbake cache but I can't explain it.

    Best regards,

    Hello @hochul yoo​ 

    I am replying to your first question: "Why doesn't rootfs include libmodbus?"

    Indeed, this package is not included into the rootfs but it is available through apt-get commands. Firstly, refresh the apt database:

    root@stm32mp1:~# apt-get update

    You can search your package and its version with these two commands:

    root@stm32mp1:~# apt-cache search libmodbus
libmodbus-doc - A Modbus library - Documentation files
libmodbus5 - A Modbus library
root@stm32mp1:~# apt-cache policy libmodbus5
libmodbus5:
 Installed: (none)
 Candidate: 3.1.6-r0
 Version table:
 3.1.6-r0 500
 500 http://packages.openstlinux.st.com/3.0 dunfell/untested armhf Packages

    and then install it on your board:

    root@stm32mp1:~# apt-get install libmodbus5

    Hello @hochul yoo​ 

    Great! I am really glad you fixed your issue.

    Was the problem related to a bitbake cache mismatch?

    Anyway, do not forget many packages are available in the OpenSTLinux distribution through apt-get commands directly from your board.

    I tried also the process to add the libmodbus :

    libmodbus add to weston image.

    in conf/local.conf

    IMAGE_INSTALL_append += "libmodbus"

    bitbake st-image-weston

    ==> result package

    /tmp-glibc/deploy/deb/cortexa7t2hf-neon-vfpv4/libmodbus5_3.1.6-r0.0_armhf.deb

    /usr/lib/libmodbus.so.5

    according to your trace, I check also if the file "lzma.h" exist:  

    tmp-glibc/sysroots-components/x86_64/xz-native/usr/include/lzma.h
