i just wrote a C program just simple one !

#include <stdio.h>
int main()
   // printf() displays the string inside quotation
   printf("Hello, World!");
   return 0;

and compiled using clang on my iOS device [ iOS 11.3.1 Electra JB

compiled using this method with (SDK 8.1)


and compiled with no problem, but when i run my program in terminal i get

iOS 11 has some problems with this. However, I think @DiDA has a fix.


Alternative: Try signing with extender from Julio (not sure if it supports signing Binary but it's worth a try)

Thank you for your reply, well i will give a try, may @DiDA have another idea !
