;){kind=small} | Cflow is the program that takes C files and prints out the call graph. |
|
|

|
|
|
;){kind=small} | Some useful options |
|
|
|||||
|
|
|
 | -d to specify the depth |
|
|
|||||
|
|
|
| -r to specify where to root the graph (main is a good place to start) |
|
|
|||||
|
|
|
| -P and -A remove commonly used keywords, like strncmp et al |
|
|
|||||
|
|
|
;){kind=small} | One way to get a reasonable graph is: |
|
|
|||||
|
|
|
| cflow -r main -d 4 $(ALL_INCLUDES) $(LTLIBRARY_SOURCES) > cflow.out cflow2dot < cflow.out > cflow.dot dot -Grankdir=LR -Tps < cflow.dot > cflow.ps |
|

|
| This is in Makefile and using the includes and stuff helps with getting everything we need as cflow is just using CPP and friends to do its work. It's really a compiler that doesn't produce objects as an output. |
