Hi guys, I have a program running the program "pfscan" on klee. I can compile pfscan via regular make and then run it, however, when i move to klee, it always gives me an error "Error: failed external call: ftw". The function "ftw" is from "/usr/include/ftw.h" (but klee-uclibc also have one copy in "uclibc_dir/include") and pfscan uses it to extract the search directory and invoke the callback func.
Is klee able to handle this function call? If not, how can i do to figure it out? use similar function to replace "ftw"? I also have a "failed external function call" on the function "fscanf", then i use "fread" instead of "fscanf" and it works. Thank you~! Daniel.
