[ast-developers] gcc -I/usr/include/ast no longer works in ast-open.2014-07-21

[Lionel Cons]

Our nextgen-grid group ran into serious trouble with the new ast-open
package - /usr/include/ast can no longer be put in front of
/usr/include for most projects.

example:
$ cat x.c
#include <sys/types.h>
#include <netinet/in.h>
#include <arpa/nameser.h>
#include <resolv.h>
int
main ()
{
/*
 * Use volatile, or else optimization can cause false positives.
 */
void (* volatile p)() = (void (*)())res_search;
  ;
  return 0;
}
$ gcc -std=gnu99 -m64 x.c -lresolv
$ echo $?
0

So this works fine.

BUT:

$ gcc -std=gnu99 -m64 -D_LARGEFILE64_SOURCE -I/usr/include/ast x.c
-lresolv -last

$ grep -r _ast_intmax_t  /usr/include/ast | fgrep define
/usr/include/ast/ast_common.h:#define _ast_intmax_t             _ast_int8_t
$ grep -r _ast_int8_t /usr/include/ast | fgrep define
/usr/include/ast/ast_common.h:#define _ast_int8_t               long
/usr/include/ast/ast_common.h:#define _ast_intmax_t             _ast_int8_t

So the basic problem is prototype mismatch - resolvepath() is obvious
and the other is long long vs long.

Glenn, Roland, we need an urgent patch. Whatever you have, please. The
whole project group is stalled after the upgrade ;-(
