From cc976614f59bd8e45de8ce988a6bcb5de711d994 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 30 Dec 2019 22:20:06 +0900 Subject: [PATCH 1/2] gen_initramfs_list.sh: fix 'bad variable name' error Prior to commit 858805b336be ("kbuild: add $(BASH) to run scripts with bash-extension"), this shell script was almost always run by bash since bash is usually installed on the system by default. Now, this script is run by sh, which might be a symlink to dash. On such distributions, the following code emits an error: local dev=`LC_ALL=C ls -l "${location}"` You can reproduce the build error, for example by setting CONFIG_INITRAMFS_SOURCE="/dev". GEN usr/initramfs_data.cpio.gz ./usr/gen_initramfs_list.sh: 131: local: 1: bad variable name make[1]: *** [usr/Makefile:61: usr/initramfs_data.cpio.gz] Error 2 This is because `LC_ALL=C ls -l "${location}"` contains spaces. Surrounding it with double-quotes fixes the error. Fixes: 858805b336be ("kbuild: add $(BASH) to run scripts with bash-extension") Reported-by: Jory A.

Since this is a build time dependency for a build tool, we need to depend on the native version of libelf-dev so add the appropriate annotation.
