Makefile doesn't update $< variable

Hello guys,

I could use advise from more experienced guys about my Makefile. In short, the problem with my Makefile is that $< doesnt change
inside my rule.

Here is my Makefile:

Code:

# Makefile for CORE

CC = gcc.exe
AS = as.exe
AR = ar.exe

INCLUDE = \
-I../lib/tomcrypt/inc \
-I../lib/tommath/inc \
-I../lib/hal_dev/traces_gnu/inc \


CFLAGS = -DCORE_SW_VERSION='"CORE.07.01.04.01.03.01.R"' -D__HAL_DBG__ -D__MQX_FIO__ -O1 -g3 -Wall -c -fmessage-length=0  -std=c99 -fgnu89-inline -mno-volatile-cache $(INCLUDE)


OBJDIR = $(shell pwd)
SOURCEDIR = ../sources
PATTERN = ..

#this scans for .c files, and there is a lot of them
CSRC := $(shell find $(SOURCEDIR) -name '*.c')

#I have also tried with CSRC = $(shell find $(SOURCEDIR) -name '*.c'), same thing

OBJ = $(CSRC:.c=.o)
OBJS = $(patsubst ../%,$(OBJDIR)/%,$(OBJ)) 



.PHONY: all
all: $(OBJS)	
	../libprocess.sh dev traces_gnu 16.01.06.01.06.00 dummy
	$(AR) -q CORE.07.01.04.01.03.01.R.a $(OBJS)	
	../release.sh dev dev CORE.07.01.04.01.03.01.R traces_gnu CORE.07.01.04.01.03.01.R.a GNU dummy

.PHONY: csrc
csrc: $(CSRC)
	$(CC) $(CFLAGS) $(CSRC)

.PHONY: asm
asm: $(SSRC)
	$(AS) $(SSRC)

.PHONY: clean
clean:
	rm -f $(OBJS)
	
$(OBJS): $(CSRC)		
	mkdir -p $(dir $@)	
	$(CC) $(CFLAGS) $< -o $@

------------------------

Now, I have printed $< inside my $(OBJS) rule and I can see that this doesn't change, that it's always first file in the line of the strings.
Do you see where is the mistake? Thanks!

Why updating atime doesn't update ctime?

Hi, ctime is the inode change time. If reading a file, its atime will be updated, which should cause inode member i_atime changed, which is an inode change. So ctime should also be updated. But if I try to ls a directory on redhat, only the directory atime gets updated, not ctime. Why? THANKS!

xmkmf

XMKMF(1)						      General Commands Manual							  XMKMF(1)

NAME

       xmkmf - create a Makefile from an Imakefile

SYNOPSIS

       xmkmf [ -a ] [ topdir [ curdir ] ]

DESCRIPTION

       The xmkmf command is the normal way to create a Makefile from an Imakefile shipped with third-party software.

       When  invoked with no arguments in a directory containing an Imakefile, the imake program is run with arguments appropriate for your system
       (configured into xmkmf when X was built) and generates a Makefile.

       When invoked with the -a option, xmkmf builds the Makefile in the current directory, and then automatically executes ``make Makefiles'' (in
       case  there are subdirectories), ``make includes'', and ``make depend'' for you.  This is the normal way to configure software that is out-
       side the X Consortium build tree.

       If working inside the X Consortium build tree (unlikely unless you are an X developer, and even then this option is never really used), the
       topdir  argument  should be specified as the relative pathname from the current directory to the top of the build tree.	Optionally, curdir
       may be specified as a relative pathname from the top of the build tree to the current directory.  It is necessary to supply curdir  if  the
       current	directory  has	subdirectories, or the Makefile will not be able to build the subdirectories.  If a topdir is given, xmkmf assumes
       nothing is installed on your system and looks for files in the build tree instead of using the installed versions.
