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!

pdl::pptemplate

pptemplate(3)						User Contributed Perl Documentation					     pptemplate(3)

NAME

       pptemplate - script to generate Makefile.PL and PP file skeleton

SYNOPSIS

	       # generate Makefile.PL and mymodule.pd in CWD
	       pptemplate PDL::MyModule;

DESCRIPTION

       The pptemplate script is the easiest way to start a new module for PDL that contains PP code (see also PDL::PP). The usage is simply

	 pptemplate modulename;

       As a result pptemplate will generate a perl Makefile for the new module (Makefile.PL) that contains the minimal structure to generate a
       module from PP code and also a skeleton file for your new module.

       The file will be called mymod.pd if you called "pptemplate" as

	 pptemplate PDL::CleverAlgs::Mymod;

       I suppose you can work out the naming rule ";)". If not resort to experimentation or the source code.

       "pptemplate" will refuse to overwrite existing files of the same name to avoid accidents. Move them out of the way if you really want to
       scrap them.

   Options
       Currently there is only the "-i" option which switches "pptemplate" into the so called internal mode.  It should only be used when you are
       starting a new module within the main PDL tree that is supposed to be part of the PDL distribution and the normal PDL build process, e.g.

	  cd PDL/IO;
	  mkdir Mpthree; cd Mpthree;
	  pptemplate -i PDL::IO::Mpthree;

BUGS

       Maybe ";)".  Feedback and bug reports are welcome.
