(In reply to comment #0) > dbus-1.4.0 fails to compile by default on Solaris with below shown errors. I think this is Bug #33465; my patch there is probably a cleaner way to fix this. > #0 0xfffffd7fff293b3b in .memsetbyte32sse2 () from /lib/64/libc.so.1 > #1 0xfffffd7ff9827d20 in _dbus_read_socket_with_unix_fds (fd=<value optimized > out>, buffer=<value optimized out>, > count=<value optimized out>, fds=<value optimized out>, n_fds=<value > optimized out>) at dbus-sysdeps-unix.c:292 This might be Bug #33466; could you try building dbus with GNU ld, or without --gc-sections (currently requires patching configure.in)? Otherwise, I have no idea what's going on there. You could try compiling without optimization to see if you can get a better backtrace? No more info provided in > 3.5 years, closing WORKSFORME. |

Created attachment 40584 [details] complete dbus segfault backtrace dbus-1.4.0 fails to compile by default on Solaris with below shown errors. I observed that this was failing because some of the struct/union member's were available conditionally in sys/socket.h. I was able to get past these errors by patching dbus/dbus-sysdeps-unix.c with below shown patch. This worked well and compilation was successful but after this I found issues with dbus while using it. one of my application's is segfaulting. I have posted backtrace of the core file which indicated an issue with dbus especially at _dbus_read_socket_with_unix_fds at line number 292 of dbus-sysdeps-unix.c compilation erros. <<< >>> make[3]: Entering directory `/var/tmp/navulurubuilds/dbus-1.4.0/dbus' CC libdbus_1_la-dbus-sysdeps-unix.lo "dbus-sysdeps-unix.c", line 283: undefined struct/union member: msg_controllen "dbus-sysdeps-unix.c", line 283: warning: implicit function declaration: CMSG_SPACE "dbus-sysdeps-unix.c", line 287: undefined struct/union member: msg_control "dbus-sysdeps-unix.c", line 287: warning: implicit function declaration: alloca "dbus-sysdeps-unix.c", line 287: improper member use: msg_controllen "dbus-sysdeps-unix.c", line 288: improper member use: msg_control "dbus-sysdeps-unix.c", line 288: improper member use: msg_controllen "dbus-sysdeps-unix.c", line 288: warning: improper pointer/integer combination: arg #1 <<< >>> sys/socket.h <<< >>> #if defined(_XPG4_2) || defined(_KERNEL) void *msg_control; /* ancillary data */ socklen_t msg_controllen; /* ancillary data buffer len */ int msg_flags; /* flags on received message */ #else caddr_t msg_accrights; /* access rights sent/received */ int msg_accrightslen; #endif /* defined(_XPG4_2) || defined(_KERNEL) */ }; <<< >>> Patch applied to dbus/dbus-sysdeps-unix.c << >> +#ifdef __sun +#define _XPG4_2 +#endif << >> backtrace of core << >> #0 0xfffffd7fff293b3b in .memsetbyte32sse2 () from /lib/64/libc.so.1 #1 0xfffffd7ff9827d20 in _dbus_read_socket_with_unix_fds (fd=<value optimized out>, buffer=<value optimized out>, count=<value optimized out>, fds=<value optimized out>, n_fds=<value optimized out>) at dbus-sysdeps-unix.c:292 #2 0xfffffd7ff981ddb9 in do_reading (transport=<value optimized out>) at dbus-transport-socket.c:800 #3 0xfffffd7ff981e4f7 in socket_do_iteration (transport=<value optimized out>, flags=<value optimized out>, timeout_milliseconds=<value optimized out>) at dbus-transport-socket.c:1162 #4 0xfffffd7ff981ca21 in _dbus_transport_do_iteration (transport=<value optimized out>, flags=<value optimized out>, timeout_milliseconds=<value optimized out>) at dbus-transport.c:981 #5 0xfffffd7ff97fa65c in _dbus_connection_do_iteration_unlocked (connection=<value optimized out>, pending=<value optimized out>, flags=<value optimized out>, timeout_milliseconds=<value optimized out>) at dbus-connection.c:1207 #6 0xfffffd7ff97fc562 in _dbus_connection_block_pending_call (pending=<value optimized out>) at dbus-connection.c:2416 #7 0xfffffd7ff97fdfb3 in dbus_connection_send_with_reply_and_block (connection=<value optimized out>, message=<value optimized out>, timeout_milliseconds=<value optimized out>, error=<value optimized out>) at dbus-connection.c:3559 #8 0xfffffd7ff97f8b17 in dbus_bus_register (connection=<value optimized out>, error=<value optimized out>) at dbus-bus.c:698 #9 0xfffffd7ff97f8658 in dbus_bus_get (type=<value optimized out>, error=<value optimized out>) at dbus-bus.c:491 #10 0xfffffd7ff98b2bd5 in get_ior (start_if_not_found=38161477, failure_log=0x300000000000000) at gconf-internals.c:2444 << >> << >> (gdb) up #1 0xfffffd7ff9827d20 in _dbus_read_socket_with_unix_fds (fd=<value optimized out>, buffer=<value optimized out>, count=<value optimized out>, fds=<value optimized out>, n_fds=<value optimized out>) at dbus-sysdeps-unix.c:292 << >> Can some quickly look at this and help me here?
