Subject: [RFC v3 1/3] kvm: selftests: Fix no directory error when OUTPUT specified
Date: Thu, 26 Mar 2020 11:07:48 +0800	[thread overview]
Message-ID: <20200326030750.173972-2-xiaoyao.li@intel.com> (raw)
In-Reply-To: <20200326030750.173972-1-xiaoyao.li@intel.com>

When build kvm selftests to an specified directory with

	make OUTPUT=/home/lxy/kvm-selftests

it encouters following error：

  /usr/bin/ld: cannot open output file
  /home/lxy/kvm-selftests/x86_64/cr4_cpuid_sync_test: No such file or
  directory
  collect2: error: ld returned 1 exit status
  make: *** [../lib.mk:141:
  /home/lxy/kvm-selftests/x86_64/cr4_cpuid_sync_test] Error 1

Use "mkdir -p" to create the directory to fix this issue.
