libcap compile error

[Remco Poelstra]

Hi all,

I’m new with the Yocto project and I’m still trying to find my way.
I’m using a Hachiko board using Architech SDK and have managed to build 
and run the standard image.
As a next step I wanted to include the avahi mdns implementation. In 
order to do so I included IMAGE_INSTALL_append = “ avahi”
When I now run bitbake, I get the following error for libcap_2.22.bb:
| cap_file.c:8:23: fatal error: sys/xattr.h: No such file or directory

The compiler has a switch 
‘--sysroot=/home/architech/architech_sdk/architech/hachiko-tiny/yocto/build/tmp/sysroots/hachiko’, 
which indeed does not include this file.
Is that the location where the file should be? How can I add it? Is this 
a more general bug in Yocto or just my local setup?

Thanks in advance.

Kind regards,

Remco Poelstra

libcap 2.22 is very old, so your SDK must be using a very old release of 
Yocto (2014 or earlier). It's difficult to provide help for that. 
Perhaps you could address your question to the makers of the SDK and 
find out if they have anything more recent?

Thanks for your fast response. I've contacted them to see if they have 
an update.

it seems you might be using uclibc, and xattr is absent in DISTRO_FEATURES, add

DISTRO_FEATURES_append = " xattr"

in your conf/local.conf and see if that helps.

Hi,

This did indeed resolve that issue. Unfortunately it didn't take long 
for another compile error to pop up. I'm investigating my options for 
moving to a more modern Yocto release. I hope that will prove to be more 
useable.
Thanks for the suggestion.

Kind regards,
