I have a directory of .pc files, and I am trying to compile to .o files with a Makefile. Oracle Pro*C precompiles the .pc files into .c. Then gcc compiles the .c files to .o. These are the rules:
%.c: %.pc
$(PROC) $(PROCPLSFLAGS) INCLUDE=$(SRCHOME) iname=$<
%.o: %.c
$(CC) $(INCLUDE) $(CFLAGS) $(PRECOMPPUBLIC) -c $<
The problem occurs when I try to build a .o file. The .c file is generated correctly, but the $(CC) line cannot find the .c file until I run make a second time. When I run the Makefile without any arguments to build the entire directory, I need to run make twice for each .pc file in the directory. How can I fix the Makefile so that it only needs to run once?
