Running make in this directory will generate a number of PDF graphs.
|
||||||
|
In the callgraph, the arrows means "calls". In the dependency graphs,
|
||||||
|
the arrows means "requires" (or "depends upon").
|
||||||
|
|
||||||
|
callgraph.pdf This shows the callgraph, i.e., what functions each
|
||||||
|
function in the program calls.
|
||||||
|
module_dependencies.pdf This shows the dependencies between the modules.
|
||||||
|
file_dependencies.pdf This shows the dependencies between the files.
|
||||||
|
makefile_dependencies.pdf This shows the dependencies required by make when
|
||||||
|
building the program.
|
||||||
|
build_dependencies.pdf This is like makefile_dependencies.pdf but shows
|
||||||
|
the operations performed to generate the new file.
|
||||||
|
|
||||||
|
callgraph.d This shows the callgraph in text format.
|
||||||
|
files.d This shows the file dependencies in text format.

modules.d This shows the module dependencies in text format.
