PHP 4.0 Bug #9239: configure tests incorrectly for IPv6

From: rhialto@polderland.nl Operating system: NetBSD any version PHP version: 4.0.4pl1 PHP Bug Type: *Install and Config Bug description: configure tests incorrectly for IPv6 From NetBSD problem report pkg/12199: http://www.NetBSD.org/cgi-bin/query-pr-single.pl?number=12199 Configure uses an incorrect test program to check for availability of IPv6. I noticed this for the php4 package but I'm sure it is a more general configure problem. This is the code that is used: #line 6338 "configure" #include "confdefs.h" #include <sys/socket.h> #include <netinet/in.h> int main() { struct sockaddr_in6 s; int i=AF_INET6; s ; return 0; } What is missing is an #include <sys/types.h>. The compilation fails with messages like configure:6333: checking for IPv6 support configure:6346: cc -c -O2 -I/usr/pkg/include -I/usr/pkg/include conftest.c 1>&5 In file included from configure:6339: /usr/include/sys/socket.h:186: syntax error before `u_char' /usr/include/sys/socket.h:214: syntax error before `u_char' /usr/include/sys/socket.h:216: `int64_t' undeclared here (not in a function) /usr/include/sys/socket.h:216: `u_char' undeclared here (not in a function) /usr/include/sys/socket.h:217: syntax error before `int64_t' and more. This is independent of actual support of IPv6. You need to add #include <sys/types.h>, as always is needed before <sys/socket.h>. See the man page for socket(2), for instance. -- Edit Bug report at: http://bugs.php.net/?id=9239&edit=1
