[SOLVED] Question about Makefile structure: is it compiling by itself?

Hello guys,

I may have to read about Makefiles quite some more, but I would like at least at hint at what to read about the following behavior at my Makefile:

I have this as my Makefile:

PHP Code:



# Makefile for the SRC folder. 
 
include ../makefile_set.inc 
 
all: double 
 
DOUBLE  = \ 
    c_mtk_double_crs_sparse_matrix_array_print.o \ 
    c_mtk_double_crs_sparse_matrix_block_print.o \ 
    c_mtk_double_crs_sparse_matrix_create_from_1d_array.o \ 
    c_mtk_tool_manager_abort.o \ 
    c_mtk_double_crs_sparse_matrix_free.o \ 
    c_mtk_double_ccs_sparse_matrix_create_from_1d_array.o \ 
    c_mtk_double_ccs_sparse_matrix_array_print.o \ 
    c_mtk_double_ccs_sparse_matrix_free.o \ 
    c_mtk_double_ccs_sparse_matrix_block_print.o 
 
double: $(DOUBLE) 
    @echo -e '----- Compiling the types in double precision: Done!\n'

BUT, when I execute make I get the following:

Code:

ejspeiro@citadel:~/Dropbox/Public/mtk/trunk/cmtk-v1.0/src$ make
cc    -c -o c_mtk_double_crs_sparse_matrix_array_print.o c_mtk_double_crs_sparse_matrix_array_print.c

But HOW? How does my makefile knows that it should execute that particular method for compiling... my problem is that I'm trying to define my own, but I will keep doing that one!

Thanks in advanced!

There are default rules. Try http://www.student.cs.uwaterloo.ca/~isg/res/unix/make/ , http://www.gnu.org/software/make/manual/make.html , etc.
