Creates a graph of dependencies from GNU-Make ( )

Output is a graphviz-dot file ( ), a Gexf-XML file ( ) or a list of the deepest independent targets that should be make.

sub-makefiles are not supported.


  • 2014-12-31 added option --format, removed otpions 'x' and 'd'
  • 2014-12-22 added 'deep' output. I need this when I'm working on a cluster and I need to know the deepest independent targets that should be make.
  • 2014-10-07 print version
  • 2014-10-06 added --root option
  • 2014-09-17 added long_opt , options basename and suffix
  • 2014-09-16 fixed new format for GNU make v4.0






  • -h|--help help (this screen)
  • -f|--format (format)

make2graph only parses english messages from GNU make. If you're using another locale, you should set LC_ALL=C.

Deep output

deep output was needed when using a cluster: I needed a list of all deepest independant targets that must be re-built.

For the following Makefile

NUMS=1 2 3 4 5
.PHONY:all clean 
%.c: %.b
	echo "$<" > $@

%.b: %.a
	echo "$<" > $@

	echo "$@" > $@

all:$(addsuffix .c,${NUMS})

	rm -f $(foreach P,a b c,$(addsuffix .${P},${NUMS})) 

make a few targets:

$ make  1.a 2.a 3.b 4.c 
echo "1.a" > 1.a
echo "2.a" > 2.a
echo "3.a" > 3.a
echo "3.a" > 3.b
echo "4.a" > 4.a
echo "4.a" > 4.b
echo "4.b" > 4.c
rm 3.a 4.a 4.b

deep output :

$ make -nd  all  | ./make2graph --format e

build other targets

$ make  1.b 3.c
echo "1.a" > 1.b
echo "3.b" > 3.c

new deep output :

$ make -nd  all  | ./make2graph --format e





@yokofakun Using your, and Graphviz 2.36 for OS X. Large graph. How can I scale it better?

try the gexf+ #gephi output or another grafviz algo like neato
