PHP 4.0 Bug #6756: sockets.c will not compile on Solaris for several reasons

From: Wolfram.Schmidt@iao.fhg.de Operating system: Solaris 2.6 PHP version: 4.0.2 PHP Bug Type: Compile Failure Bug description: sockets.c will not compile on Solaris for several reasons socket.c fails to compile in line 849 reason: struct sockaddr_un *sun; sun is predefined on SunOS-es. struct sockaddr_un *1; will not compile and won't make sense if it would. Just checked that this is not in CVS yet :-) Ummm... Just recognized that "sun" is used in several functions in socket.c. After having exchanged replaced "sun" with "s_un" the following error occures: "sockets.c", line 1580: undefined struct/union member: msg_control To get the version of of msghdr in <sys/socket.h> which contains msg_control and some other undefined members _XPG4_2 has to be defined which must not be defined directly bit can be obtained via defining _XOPEN_SOURCE and _XOPEN_SOURCE_EXTENDED=1. See <sys/feature_tests.h> defining the two constants in CPPFLAGS and rerunnign configure gives me: ... checking for NSAPI include files... Netscape-Enterprise/3.x style configure: error: ZTS currently requires working POSIX threads. Your system does not support this. Now I'm lost.
