[yocto] [qemu] can't find qemu-native recipe

[Greg Wilson-Lindberg]

Hi Khem,

And just after I hit send I realized that I changed 'SRC_URI' to 'SRC_URII_append_class-native' with the 'II'. I deleted the 'II' and now the file is changed like it should be.

Thanks fo all of your help,

Greg Wilson-Lindberg

Hi Khem,
I found the BBCLASSEXTEND in the qemu.inc file, I also found a line in the .bb file:
SRC_URI_append_class-native = " \

so I changed my SRC_URI to that and I stopped getting the 'can't find file to patch' error, but the file (syscall.c) is not modified.

Here is my qemu_3.0.0.bbappend file, meta-sakura/recipes-devtools/qemu/qemu_3.0.0.bbappend:
FILESEXTRAPATHS_prepend := "${FILE_DIRNAME}/${PN}:"

SRC_URII_append_class-native = "file://syscall.c-add_missing_sockios_header_include.patch"

And here is the patch file .../qemu/syscall.c-add_missing_sockios_header_include.patch:
--- a/linux-user/syscall.c    2019-11-18 09:42:39.000000000 -0800

I am not getting the: 
...tmp/work/x86_64-linux/qemu-native/3.0.0-r0/qemu-3.0.0/linux-user/syscall.c
modified.

I'm obviously missing something. Any help would be greatly appreciated.

Regards,
Greg

I can find a number of recipes that depend in one way or another on 'qemu-native', but I can't find a recipe, class for it or anything that provides it. I can see it being built, and I get an error that indicates that the patch that I have needs to be applied. I can find tmp/work/x86_64-linux/qemu-native/.

there must be BBCLASSEXTEND = "native" in qemu recipe which
essentially automatically extends the recipe for native case

see
