Cgrapher4gcc is a tool from the Kayrebt tool set. Its purpose is to extract automatically pseudo-UML2 activity diagrams from functions of the Linux kernel. The diagrams can be useful for software visualization, static analysis, etc.


Cgrapher4gcc receives two files as parameters : a file containing a list of functions to draw and a file containing a list of files to compile containing those functions (in order to avoid compiling the entire kernel to extract the graph of one or two functions).

Parameters: -s : the file containing the list of source files to compile (default: "sources") -f : the file containing the list of functions to graph (default: "functions") -k: do not remove temporary files at the end of the execution -t : select a different sources tree than the default one -V : select a specific commit in the kernel tree for diagram extraction (default: "master")


Cgrapher4gcc produces a graph under png format for each function in the function list file that was compiled.

Think to check your private token in your account first. You can find more detail in our documentation tab.

This app id is : 34

This curl command will create a job, and return your job url, and also the average execution time

files and/or dataset are optionnal, think to remove them if not wanted
curl -H 'Authorization: Token token=<your_private_token>' -X POST
-F job[webapp_id]=34
-F job[param]=""
-F job[queue]=standard
-F files[0]=@test.txt
-F files[1]=@test2.csv
-F job[file_url]=<my_file_url>
-F job[dataset]=<my_dataset_name>

Then, check your job to get the url files with :

curl -H 'Authorization: Token token=<your_private_token>' -X GET<job_id>
