Hi I am adding ICU to my build. I am bitbaking my own recipe.

bitbake dai-image-hello

In this i just added one hello world source, freetyp62 and ICU packages.

In ICU total 7.so files will be generated. When I chacked in the build folder

when I do bitbake -c compile icu and bitbake icu

Build/tmp/work/cortexa7hf-vfp-neon-poky-linux-gnueabi/icu/54.1/ all the 7 libraries got generated

libicudata.so.54.1 libicui18n.so.54.1 libicuio.so.54.1 libicule.so.54.1 libiculx.so.54.1 libicutu.so.54.1 libicuuc.so.54.1

When I do bitbake dai-image-hello only 5 so files are getting copied to rootfs.

libicudata.so.54.1,libicui18n.so.54.1,libicuio.so.54.1, libicutu.so.54.1, libicuuc.so.54.1

dai-image-hello.bb is my image bitbake file contents are

include recipes-core/images/core-image-base.bb

IMAGE_INSTALL += " \
   helloworld \
   icu \
   freetype \
"

export IMAGE_BASENAME = "dai-image-hello"

attached are the ICU related bb files and include files

Original Attachment has been moved to: icu.inc.zip

Original Attachment has been moved to: icu_54.1.bb.zip

Hi igorpadykov‌

The links doesn't provide any solution. I already have experience in working with ICU on UBUNTU machine. I am trying to port the same thing with I.Mx6 using yocto.

the problem is in the final rootfs ICU header files and some of the ICU shared libraries are not installed even though there is no error in compiling the package. Out of 8 libraries only 5 are getting installed.

i got the solution

I came to know that recipes and packages differ. I searched for ICU packages and gave the correct package name which installs all the libraries

After reading from the below link i got the right package and then everything got installed

Thank you
