Re: [yocto] How to use *.bb file to select different kernel config/feature?

They can take a variety of overrides, one of which is the machine name. So yes, you could append a kernel feature only for your $MACHINE with the line above. But you must be using a kernel recipe that inherits kernel-yocto for the feature to be processed. KERNEL_CONFIG_box1=" cfg/box1_defconfig.cfg" Assuming KERNEL_CONFIG is a valid variable in your layers, this would also work. But if you are using configuration fragments and kernel-yocto, that isn't a variable that is used. Bruce this instruction could work?or any suggestion.

There is work ongoing to allow BSPs to extend runqemu so this could work, but for now if you wish to run images in qemu frequently then it's recommended to use the qemux86-64 machine, as it will include a few pieces (kernel modules, graphics drivers, etc) which increase performance inside qemu.

[yocto] libnetconf recipe configure error
Hi all
I write a libnetconf recipe BB file to handle this package.
Like this:
DESCRIPTION = "libnetconf is a NETCONF library."
HOMEPAGE = "https://github.com/CESNET/libnetconf";
SECTION = "devel"
LICENSE = "BSD"
LIC_FILES_CHKSUM =
"file://${WORKDIR}/git/COPYING;md5=22c218798908f95216326c4df42637b5"
DEPENDS += "libssh libxml2 libxslt openssl "
SRC_URI = "git://github.com/CESNET/libnetconf.git;procotol=https"
SRCREV="d4585969d71b7d7dec181955a6753b171b4a8424"
S = "${WORKDIR}/git"
inherit autotools
END##
The problem is libxslt. The libnetconf depends on it. Although I have put
libxslt into DEPENDS, the 'configure' of libnetconf can't finish.
I find all libxslt content was built, locate at sysroot like '/usr/lib/...'
and '/use/include/libxslt/...'
Is there something wrong of my BB file or libxslt NOT build correctly?
Btw. The libxml2 is very fine.
