Linux, по какой-то причине, все еще использует SUSv1 для этого API, где nftw () все еще считается расширением.
На странице руководства Linux , include должно быть:
#define _XOPEN_SOURCE 500
#include <ftw.h>

Hmm. Your code works for me. Check your include paths, maybe? Though this is a system header, so it should be pretty hard to miss this. Or were you accidentally compiling a version that didn't have the #include line?
$ gcc -o ftw ftw.c
$ ./ftw my-directory

... etc ...
edit: The test above was done on Mac OS X. In a (now deleted) comment the OP mentioned he was on Debian, for which the man page mentions that #define _XOPEN_SOURCE 500 is necessary, as Juliano points out.
