file permission error during make after source change

[ckim]

Hello,

I added a debug print code in the source (5.1.0) in hw/arm/virt.c and tried ‘make’,

But it gives me error telling me some files are not writable.

I found those files under aarch64-softmmu and trace are not writeable for normal user.

For example aarch64-softmmu/config-devices.mak.old and trace/generated-tcg-tracers.h-timestamp are two of those files.

What is the proper way of ‘make’ after the source change?

(because I could run ‘make’ and ‘sudo make install’ before, I’m curis why second ‘make’ is not possible)

Thank you
