commit: c353acba28fb3fa1fd05fd6b85a9fc7938330f9c From: Sascha Hauer <[email protected]> Date: Thu, 4 Oct 2012 17:11:17 -0700 Subject: kbuild: make: fix if_changed when command contains backslashes
The call if_changed mechanism does not work when the command contains backslashes. This basically is an issue with lzo and bzip2 compressed kernels. The compressed binaries do not contain the uncompressed image size, so these use size_append to append the size. This results in backslashes in the executed command. With this if_changed always detects a change in the command and rebuilds the compressed image even if nothing has changed. Fix this by escaping backslashes in make-cmd Signed-off-by: Sascha Hauer <[email protected]> Signed-off-by: Jan Luebbe <[email protected]> Cc: Sam Ravnborg <[email protected]> Cc: Bernhard Walle <[email protected]> Cc: Michal Marek <[email protected]> Cc: <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]> --- scripts/Kbuild.include | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/scripts/Kbuild.include b/scripts/Kbuild.include index 6a3ee98..afa4459 100644 --- a/scripts/Kbuild.include +++ b/scripts/Kbuild.include @@ -209,7 +209,7 @@ endif # >$< substitution to preserve $ when reloading .cmd file # note: when using inline perl scripts [perl -e '...$$t=1;...'] # in $(cmd_xxx) double $$ your perl vars -make-cmd = $(subst \#,\\\#,$(subst $$,$$$$,$(call escsq,$(cmd_$(1))))) +make-cmd = $(subst \\,\\\\,$(subst \#,\\\#,$(subst $$,$$$$,$(call escsq,$(cmd_$(1)))))) # Find any prerequisites that is newer than target or that does not exist. # PHONY targets skipped in both cases. -- 1.7.3.4 -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
