Hi, More and more users complain with 0.9.27 bugs which are solved by mob. They often tell us they are using ./tcc –v => 0.9.27 which is meaningless as 0.9.27 is anything form last >3y old official 0.9.27 to mob. To improve this, I would like to add the git last date (or anything that can easily identify the source code version used to compile tcc). ./tcc –v jullien@sims4:~/tinycc $ ./tcc -v tcc version 0.9.27 (ARM eabihf Linux - git version Thu Mar 18 22:54:24 2021) When tcc is compiled from a tarball (w.o. git info) it will tell: jullien@sims4:~/tinycc $ ./tcc -v tcc version 0.9.27 (ARM eabihf Linux - unknown git version) Can I push this patch? jullien@sims4:~/tinycc $ git diff diff --git a/Makefile b/Makefile index 6d09b65..691a2d3 100644 --- a/Makefile +++ b/Makefile @@ -24,6 +24,12 @@ CFLAGS += -I$(TOP) CFLAGS += $(CPPFLAGS) VPATH = $(TOPSRC) +TCC_GIT_DATE=$(shell which gut > /dev/null 2>&1 && git log -1 --format=%ad --date=local || echo no) + +ifneq ($(TCC_GIT_DATE),no) + CFLAGS += -DTCC_GIT_DATE="\"$(TCC_GIT_DATE)\"" +endif + ifdef CONFIG_WIN32 CFG = -win ifneq ($(CONFIG_static),yes) diff --git a/tcc.c b/tcc.c index bd9ce2f..36f4af1 100644 --- a/tcc.c +++ b/tcc.c @@ -181,6 +181,12 @@ static const char version[] = " NetBSD" #else " Linux" +#endif +#ifdef TCC_GIT_DATE + " - git version " + TCC_GIT_DATE +#else + " - unknown git version" #endif ")\n" ; |
