Host OS: Ubuntu 16.04 LTS x86\_64  
Target: ConnectCore i.MX6UL Starter  
Target OS: Embedded Linux  
Build Environment: DEY-2.2 | cortexa7hf-neon-dey-linux-gnueabi dey-2.2-r3 toolchain  
Issue: Can’t find libbeecrypt.so shared library

I installed the pre-compiled toolchain following this link:

> **[ConnectCore 6UL SBC Express | DEY-2.2](https://docs.digi.com/resources/documentation/digidocs/90001548/)**

Then exported the toolchain environment by:

# . /opt/dey/2.2-r3/environment-setup-cortexa7hf-neon-dey-linux-gnueabi

When trying to cross compile my application, the linker real-ld says that the -lbeecrypt library is not found.  
-lbeecrypt is included in my LDFLAGS Makefile.

On the environment-setup-cortexa7hf-neon-dey-linux-gnueabi, the linker is configured as the following:

# export SDKTARGETSYSROOT=/opt/dey/2.2-r3/sysroots/cortexa7hf-neon-dey-linux-gnueabi

# export LD=“arm-dey-linux-gnueabi-ld --sysroot=$SDKTARGETSYSROOT”

I tried to search for libbeerypt.so on the cross compile toolchain installed under:  
/opt/dey/2.2-r3  
It’s neither under sysroots/cortexa7hf-neon-dey-linux-gnueabi/lib directory nor sysroots/cortexa7hf-neon-dey-linux-gnueabi/usr/lib directory.  
Where (lib and usr/lib) I can find all other libraries that I need to compile my application, included in my LDFLAGS Makefile.

But I can find the beecrypt sources under:  
sysroots/cortexa7hf-neon-dey-linux-gnueabi/usr/src/debug/rpm/5.4.16-r0/rpm-5.4.15/beecrypt

My question is how to build these beecrypt sources to generate a libbeecrypt.so shared library included in lib or usr/lib directories ?  
This way the linker real-ld can match with -lbeecrypt library.

Thanks in advance for your help.

Regards.

try to add it to your workspace project for your platform, bitbake it, then do “bitbake -c populate\_sdk dey-image-qt”  
This should generate both target images and sdk that include the library. Once its there you can find where it goes if you still want to.

Hi Leonid,

Thanks for your answer.

I did it but a bit differently.

On my dey-image-tiny, I added the beecrypt package to the IMAGE\_INSTALL, then bitbake this image.

After flashing the target with this new image, I found under /usr/lib directory these two shared libraries:  
libbeecrypt.so.7 & libbeecrypt.so.7.0.0 .

I took the libbeecrypt.so.7, renamed it to libbeecrypt.so and put it in the cross compile toolchain under:  
/opt/dey/2.2-r3/sysroots/cortexa7hf-neon-dey-linux-gnueabi/usr/lib/

It worked, because I have no more the error telling that the linker real-ld couldn’t find -lbeecrypt .

Regards.
