When performing the out-of-tree kernel 4.19 building, some error happened saying: cannot touch 'certs/pubring.gpg'. The detail can be checked in Gitee issue #I39160 or Bug 6 of openeuler bugzilla.
This patch will fix that build error.
Hi Zhichang
few days ago, I sent a patch to solve this issue:
https://mailweb.openeuler.org/hyperkitty/list/kernel@openeuler.org/thread/O7...
I know what is the original touch operation for now. Thanks for your information!
Compared with this patch, I prefer the idea of previous implementation. Just because I personally don't like the checking on the existence of 'certs/pubring.gpg' with 'ls' :)
of-course, your patch keeps the certs directory untouched. So, your patch is also OK for me. Otherwise, we probably need to add the empty 'pubring.gpg' to variable of 'clean-files'.
With a small suggestion, what about to use inline command of 'test'?
ifdef CONFIG_PGP_PRELOAD_PUBLIC_KEYS have_pubring_gpg := $(if $(shell test -s $(srctree)/certs/pubring.gpg), -DHAVE_PUBRING_GPG) ifdef have_pubring_gpg AFLAGS_system_certificates.o += $(have_pubring_gpg) $(obj)/system_certificates.o: $(srctree)/certs/pubring.gpg endif endif
Cheers, Erik
Please let me know if you have any comment on it.
Thanks
