            Bug ID: 15271
              Host: Qemu
             Build: Ubuntu 22 X86_64
           Summary: no start-qemu.sh

Created attachment 9481
  --> https://bugs.busybox.net/attachment.cgi?id=9481&action=edit
usage: make BR2_EXTERNAL=/mnt/ramdisk/my_external_tree -C buildroot
my_qemu_x86_defconfig

Buildroot can't produce start-qemu.sh with my my_qemu_x86_defconfig. Why?

git clone https://github.com/buildroot/buildroot
make qemu_x86_defconfig -C buildroot
make -C buildroot

There is buildroot/output/images/start-qemu.sh (and also rootfs.ext2 bzImage).
Ok. Next:

make clean -C buildroot
#copy linux.config with new name
cp /mnt/ramdisk/buildroot/board/qemu/x86/linux.config
/mnt/ramdisk/my_external_tree/board/my_company/my_board/my_linux.config

#copy qemu_x86_defconfig with new name
cp /mnt/ramdisk/buildroot/configs/qemu_x86_defconfig
/mnt/ramdisk/my_external_tree/configs/my_qemu_x86_defconfig

nano /mnt/ramdisk/my_external_tree/configs/my_qemu_x86_defconfig
# and change BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE like this
BR2_LINUX_KERNEL_CUSTOM_CONFIG_FILE="/mnt/ramdisk/my_external_tree/board/my_company/my_board/my_linux.config",
save

make BR2_EXTERNAL=/mnt/ramdisk/my_external_tree -C buildroot
my_qemu_x86_defconfig
make -C buildroot

There is no buildroot/output/images/start-qemu.sh ("No Qemu cmd line found,
can't test"). There are buildroot/output/images/bzImage and
buildroot/output/images/rootfs.ext2 only. Why?

And also I see another thing like a bug:
--make clean doesn't remove .br2-external files--

After my success building
make clean -C buildroot
make BR2_EXTERNAL=/mnt/ramdisk/my_external_tree -C buildroot
my_qemu_x86_defconfig
make -C buildroot

I try
make clean -C buildroot

But in /mnt/ramdisk/buildroot/output/ there are 9 .br2-external... files. Why 
make clean -C buildroot
doesn't remove this files?
