"$?" not picking up files


hi,
I am new to shell scripting and need help.
I have the following command in makefile;

$(CC) -DLOGFLAG=1 $(CFLAGS) -o $@ -c $?

when I run the make file, I get the output like

gcc -Wall -DLOGFLAG=1 -I../ -I/appl/oraclient/product/11g/precomp/public -w -I/opt/profile/OraAlert_test/code/pwutils -I/opt/profile/OraAlert_test/code/jslib/src -o oraGen.o -c /opt/profile/OraAlert_test/code/database/src

$@ is substituted by the name of .o file. I expect @? to pick up the name of C file. but it is picking up only the location of the C file and not the exact file. How can this be solved?

Thanks.

probably you wanted to write $< instead of $?, but it also depends on the target: line of your makefile

Hi pan64,
Even after replacing $? by $< , I get the same error.

This is complete line in the makefile:

$(MCB_OBJS) $(ARC_OBJS) $(SYS_OBJS) $(SCRIPT_OBJS) $(ALERTDOBJS): $(SRCDIR)$(@:.o=.c)
$(CC) -DLOGFLAG=1 $(CFLAGS) -o $@ -c $<

see man page of gnu make, maybe this will work:
Code:
(MCB_OBJS) $(ARC_OBJS) $(SYS_OBJS) $(SCRIPT_OBJS) $(ALERTDOBJS): %.o: $(SRCDIR)%.c
<tab>$(CC) -DLOGFLAG=1 $(CFLAGS) -o $@ -c $(SRCDIR)$<
I do not know if $(SRCDIR) - the red text - required, so try
