[devel] clang 17 and stddef.h

[Vitaly Lipatov]

Подскажите, как такое может быть:

$ cat z.c
#include <stdlib.h>
#include <unistd.h>
#include <string.h>

     int main(void)
     {
         return mkstemp("abc");
     }


$ clang z.c
In file included from z.c:1:
/usr/include/stdlib.h:32:10: fatal error: 'stddef.h' file not found
    32 | #include <stddef.h>
       |          ^~~~~~~~~~
1 error generated.

$ clang -v
ALT Linux Team clang version 17.0.1

(это в hasher так, а в системе с Сизифом собирается)

Странно. АУМВР:

  % clang --version
  ALT Linux Team clang version 17.0.2
  Target: x86_64-unknown-linux-gnu
  Thread model: posix
  InstalledDir: /usr/bin
  % cat x.c
  #include <stdlib.h>
  #include <unistd.h>
  #include <string.h>
  
      int main(void)
      {
          return mkstemp("abc");
      }
  % rm -f a.out
  % clang x.c && file --mime a.out
  a.out: application/x-pie-executable; charset=binary

В нашем сообществе, как я понимаю, принято говорить в таких ситуациях
"Попробуйте ещё раз. :)".
