Yocto compilation

sergio_dorazio — Wed, 24 Jul 2019 14:44:37 GMT

Hi,

I am using yocto project for compile my linux on IMX6ULL EVK.

I am starting from Image 'core-image-base' and I am adding some modules with command IMAGE_INSTALL_append = "lighttpd curl libstdc++ bluez5" in local.conf file.
I build with bitbake command and I have a file system with new modules.

But when I run these mudules there are errors: some library file not found because the folder 'modules' in '~/imx-yocto-bsp/Linux-RCA2/tmp/deploy/images/imx6ull14x14evk' is not update with new modules, infact the date of this folder is old.

What is the command for update this folder ?

By.

Sergio.

The library files not found are for example : mod_proxy.so, mod_status.so, .....

Try cleaning and rebuilding, and see if that helps:

bitbake -c clean core-image-base

bitbake -c cleansstate core-image-base

bitbake core-image-base

You can always brute force build everything by deleting the tmp/, cache/ and sstate-cache/ folders and rebuilding. Not a very good solution though, it builds everything from scratch again.

Hello Sergio,

The cleanall command should clean up the entirety of the downloaded sources and compiled binaries, which would force everything to be build again.

I hope this helps!
