I am using ubuntu 18.04 terminal

Here's the python script I wrote to find all include files and run clang
-fsanitize

# run with python3 in terminal

import subprocess
import os

relativedir="../bsps/sparc/erc32/btimer"
directory=os.path.join(os.getcwd(),"../")
file="btimer.c"
root_dir="ubsan"

arr=['clang','-target','sparc','-fsanitize=undefined',"-I../../../../../../rtems/5/sparc-rtems5/erc32/lib/include","-I../../../../../../rtems/5/sparc-rtems5/include/"]

for path, subdirs, files in os.walk(directory):
        for subdir in subdirs:
            if(subdir=="include"):
                includepath=os.path.join(path,subdir)
                idx=includepath.find("..")
                arr.append("-I../../../../"+includepath[idx+3:])
arr.append(file)
subprocess.run(arr,cwd=relativedir, stdout=subprocess.PIPE)
#result=subprocess.run(['./a.out'],cwd=relativedir, stdout=subprocess.PIPE)
