Re: [linux-yocto] how to add recipe-sysroot-native to PKG_CONFIG_PATH for linux-yocto
Yes, kallsyms is a helper program for handling symbols during kernel build and is not itself transferred to target. For the kernel, it is essentially used for the target, but its compilation process needs native tools like kallsyms. Is this case not be considered in Yocto at the beginning? Anyway, I will look for a suitable place to adjust the settings of the PKG_CONFIG_PATH variable, or bypass the call to pkg-config, thank you.

Re: [linux-yocto] how to add recipe-sysroot-native to PKG_CONFIG_PATH for linux-yocto
Hi Alex, thank you so much for your quick reply.
In fact, I just modified the linux-yocto_5.0.bb file directly:
~/code/poky_new/poky$ git diff meta/recipes-kernel/linux/linux-yocto_5.0.bb
Diff --git a/meta/recipes-kernel/linux/linux-yocto_5.0.bb

Related dependencies, such as pkgconfig, glib-2.0 and zlib, have been added
above, since kallsyms was built during kernel compilation, I think they
should are all build-time native dependencies.
The key point now is that the PKG_CONFIG_PATH variable contains the
relevant directory for the recipe-sysroot, but the required glib-2.0.pc
file is placed naturally under the recipe-sysroot-native subdirectory.
So I need to find a way to add the recipe-sysroot-native subdirectory to
PKG_CONFIG_PATH, so that pkg-config tool can find the glib-2.0.pc file.

Re: [linux-yocto] how to add recipe-sysroot-native to PKG_CONFIG_PATH for linux-yocto
You probably need to add a dependency on glib-2.0 to your recipe, then
the needed pkgconfig will be in the target sysroot.
If you can copy-paste the entire recipe, that would help.

[linux-yocto] how to add recipe-sysroot-native to PKG_CONFIG_PATH for linux-yocto
Hi all:
I'm adding some kernel extensions to poky. In summary, I need to extend
kallsyms, and the new functionality depends on glib-2.0.
So I added pkg-confi in the ./scripts/Makefile:
HOSTCFLAGS_kallsyms.o := $(shell pkg-config --cflags glib-2.0)
-I$(srctree)/scripts
HOSTLDLIBS_kallsyms := $(shell pkg-config --libs glib-2.0) -ldw
But when compiling with bitbake, the following error occurs:
| Package glib-2.0 was not found in the pkg-config search path.
| Perhaps you should add the directory containing `glib-2.0.pc'
| to the PKG_CONFIG_PATH environment variable
| No package 'glib-2.0' found
Extrat the setting of PKG_CONFIG_PATH from temp/run.do_compile:
Export
PKG_CONFIG_PATH="/home/hchan/code/poky_new/poky/build_ctd/tmp/work/qemux86_64-poky-linux/linux-yocto/5.0.7+gitAUTOINC+d26eec23cf_891531d68e-r0/recipe-sysroot/usr/lib/pkgconfig
:/home/hchan/code/poky_new/poky/build_ctd/tmp/work/qemux86_64-poky-linux/linux-yocto/5.0.7+gitAUTOINC+d26eec23cf_891531d68e-r0/recipe-sysroot/usr/share/pkgconfig"
Look at the recipe-sysroot directory, where there is no corresponding
glib-2.0.pc file, but in the recipe-sysroot-native directory, there is:
./recipe-sysroot-native/usr/lib/pkgconfig/glib-2.0.pc
So my question is how to insert recipe-sysroot-native directory to
PKG_CONFIG_PATH variable?
I am not particularly familiar with poky/bitbake at the moment. By
searching, I found these assignments. But not sure where to add it, and how
to add:
Hchan@hchan-ThinkPad:~/code/poky_new/poky$ grep --color -rnH 'export
PKG_CONFIG_PATH=' ./meta*
./meta/recipes-devtools/pkgconfig/pkgconfig/pkg-config-native.in:3:export
PKG_CONFIG_PATH="@PATH_NATIVE@"
./meta/recipes-devtools/qemu/qemu.inc:85: export
PKG_CONFIG_PATH=$PKG_CONFIG_PATH:$BHOST_PKGCONFIG_PATH
./meta/classes/toolchain-scripts.bbclass:49: echo 'export
PKG_CONFIG_PATH=$SDKTARGETSYSROOT'"$libdir"'/pkgconfig:$SDKTARGETSYSROOT'"$prefix"'/share/pkgconfig'
>> $script
./meta/classes/toolchain-scripts.bbclass:72: echo 'export
PKG_CONFIG_PATH=${PKG_CONFIG_PATH}' >> $script
