From 6dc4627ef4eb40aeb9b328270b189ca27c061f7a Mon Sep 17 00:00:00 2001 From: Brandon Casey Date: Thu, 7 Aug 2008 14:06:26 -0500 Subject: [PATCH] Makefile: add a target which will abort compilation with ancient shells This adds a make target which can be used to try to execute certain shell constructs which are required for compiling and running git. This patch provides a test for the $() notation for command substition which is used in the Makefile and extensively in the git scripts. The make target is named in such a way as to be a hint to the user that SHELL_PATH should be set to an appropriate shell. If the shell command fails, the user should receive a message similar to the following: make: *** [please_set_SHELL_PATH_to_a_more_modern_shell] Error 2 Signed-off-by: Brandon Casey Signed-off-by: Junio C Hamano --- Makefile | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/Makefile b/Makefile index 61fc86d96..90c5a131b 100644 --- a/Makefile +++ b/Makefile @@ -1062,7 +1062,7 @@ export TAR INSTALL DESTDIR SHELL_PATH SHELL = $(SHELL_PATH) -all:: $(ALL_PROGRAMS) $(BUILT_INS) $(OTHER_PROGRAMS) GIT-BUILD-OPTIONS +all:: shell_compatibility_test $(ALL_PROGRAMS) $(BUILT_INS) $(OTHER_PROGRAMS) GIT-BUILD-OPTIONS ifneq (,$X) $(foreach p,$(patsubst %$X,%,$(filter %$X,$(ALL_PROGRAMS) $(BUILT_INS) git$X)), $(RM) '$p';) endif @@ -1075,6 +1075,11 @@ endif $(QUIET_SUBDIR0)perl $(QUIET_SUBDIR1) PERL_PATH='$(PERL_PATH_SQ)' prefix='$(prefix_SQ)' all $(QUIET_SUBDIR0)templates $(QUIET_SUBDIR1) +please_set_SHELL_PATH_to_a_more_modern_shell: + @$$(:) + +shell_compatibility_test: please_set_SHELL_PATH_to_a_more_modern_shell + strip: $(PROGRAMS) git$X $(STRIP) $(STRIP_OPTS) $(PROGRAMS) git$X @@ -1457,6 +1462,7 @@ endif $(RM) GIT-VERSION-FILE GIT-CFLAGS GIT-GUI-VARS GIT-BUILD-OPTIONS .PHONY: all install clean strip +.PHONY: shell_compatibility_test please_set_SHELL_PATH_to_a_more_modern_shell .PHONY: .FORCE-GIT-VERSION-FILE TAGS tags cscope .FORCE-GIT-CFLAGS .PHONY: .FORCE-GIT-BUILD-OPTIONS -- 2.26.2
