Module: sip-router Branch: master Commit: 51690b9e45be569ca87e6d0af9e288a3656249f3 URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=51690b9… Author: Andrei Pelinescu-Onciul <andrei(a)iptel.org> Committer: Andrei Pelinescu-Onciul <andrei(a)iptel.org> Date: Wed Jun 24 21:11:24 2009 +0200 makefile: auto-generate autover.h based on the git sha Automatically re-generate autover.h each time some change in the repository happens. The file will contain a macro (REPO_VER) set to the first 6 letters of the git sha. This allows unique identification for the git branch and commits from which the code was generated. If the code is not compiled from a git repository, use "unknown" for the REPO_VER. --- Makefile | 25 ++++++++++++++++++++++++- Makefile.targets | 2 +- 2 files changed, 25 insertions(+), 2 deletions(-) diff --git a/Makefile b/Makefile index 2dc955b..68eff8c 100644 --- a/Makefile +++ b/Makefile @@ -77,7 +77,7 @@ endif auto_gen=lex.yy.c cfg.tab.c #lexx, yacc etc -auto_gen_others=cfg.tab.h # auto generated, non-c +auto_gen_others=cfg.tab.h autover.h # auto generated, non-c COREPATH=. #include source related defs @@ -394,8 +394,13 @@ modules_search_path=$(subst $(space),:,$(strip\ $(foreach m,$(modules_dirs),$($(m)_target)))) # $(addprefix $(modules_target),$(modules_dirs)))) +# special depends for main.o +main.o: autover.h main.o: DEFS+=-DMODS_DIR='"$(modules_search_path)"' +#special depends for core_cmd.o +core_cmd.o: autover.h + include Makefile.shared ifeq ($(config_mak),1) @@ -445,6 +450,24 @@ modules-cfg modules-list modules-lst: rm -f modules.lst $(MAKE) modules.lst +ifneq ($(wildcard .git),) +# if .git/ exists +repo_ver=$(shell git rev-parse --short=6 HEAD 2>/dev/null || echo "unknown" ) +autover_h_dep=.git +else +# else if .git/ does not exist +repo_ver="unknown" +autover_h_dep= +endif + +autover.h: $(autover_h_dep) + @echo "generating autover.h ($(autover_h_dep)) ..." + @echo "/* this file is autogenerated by make autover.h" >$@ + @echo " * DO NOT EDIT IT" >>$@ + @echo " */" >>$@ + @echo "" >>$@ + @echo "#define REPO_VER \"$(repo_ver)\"" >>$@ + .PHONY: all all: $(NAME) every-module diff --git a/Makefile.targets b/Makefile.targets index 0416b80..9ba0ef8 100644 --- a/Makefile.targets +++ b/Makefile.targets @@ -35,7 +35,7 @@ doc_targets:= README man install-doc install-man install-ser-man \ # auxiliary: maintance, debugging, etc. (don't affect code/objects) aux_targets:= TAGS tar dist cfg-defs cfg config config.mak print-modules \ dbg dbinstall librpath.lst makecfg.lst modules.lst modules-cfg \ - modules-list modules-lst mk-install_dirs + modules-list modules-lst mk-install_dirs autover.h # other targets that don't produce code in the current directory ("external") ext_targets:= every-module $(modules_dirs) libs utils \ install-cfg install-utils install-modules-all install-every-module\
