Unable to free const pointers in C

Question

How can I free a const char*? I allocated new memory using malloc, and when I\'m trying to free it I always receive the error \"incompatible pointe

Several people have posted the right answer, but they keep deleting it for some reason. You need to cast it to a non-const pointer; free takes a void*, not a const void*:

free((char*)str);
