Hi, I am trying to run a pthread based application on the AMD au1500 mips processor for linux version 2.4.21pre. The pthread_create function does not return, i am attaching the strace of the process, where pthread_create() is the call after the write statement "Creating a thread". The thread seems to go into a sigsuspend mode after doing a clone() and it never seems to return from there and so the thread creation operation does not complete. Are there any patches that i need to apply or Are there any specific define flags to be enabled for compilation. Please let me know if i can run thread applications on mips. Thanks and Regards, rahul write(1, "Creating a thread\n", 18Creating a thread ) = 18 getrlimit(RLIMIT_STACK, {rlim_cur=8192*1024, rlim_max=RLIM_INFINITY}) = 0 setrlimit(RLIMIT_STACK, {rlim_cur=2044*1024, rlim_max=RLIM_INFINITY}) = 0 brk(0x10003000) = 0x10003000 pipe([721840640, 4230684]) = 4 clone(child_stack=0x100027a8, flags=CLONE_VM|CLONE_FS|CLONE_FILES|CLONE_SIGHAND) = 385 [pid 384] write(5, "\200\373\363*\5\0\0\0\0\0\0\0\377\377\377\377 y\377\177".. ., 148 <unfinished ...> [pid 385] rt_sigprocmask(SIG_SETMASK, ~[TRAP 33], <unfinished ...> [pid 384] <... write resumed> ) = 148 [pid 385] <... rt_sigprocmask resumed> NULL, 16) = 0 [pid 384] rt_sigprocmask(SIG_SETMASK, NULL, <unfinished ...> [pid 385] read(4, <unfinished ...> [pid 384] <... rt_sigprocmask resumed> [32], 16) = 0 [pid 385] <... read resumed> "\200\373\363*\5\0\0\0\0\0\0\0\377\377\377\377 y\ 377\177"..., 148) = 148 [pid 384] write(5, "\300\235\272*\0\0\0\0\0\0\0\0\244|\265*\260\345\300*\0"... , 148 <unfinished ...> [pid 385] poll( <unfinished ...> [pid 384] <... write resumed> ) = 148 [pid 385] <... poll resumed> [{fd=4, events=POLLIN, revents=POLLIN}], 1, 2000) = 1 [pid 384] rt_sigprocmask(SIG_SETMASK, NULL, <unfinished ...> [pid 385] getppid( <unfinished ...> [pid 384] <... rt_sigprocmask resumed> [32], 16) = 0 [pid 385] <... getppid resumed> ) = 384 [pid 384] sigsuspend(~[HUP INT QUIT TRAP IOT EMT FPE KILL SEGV USR1] <unfinish ed ...> [pid 385] read(4, "\300\235\272*\0\0\0\0\0\0\0\0\244|\265*\260\345\300*\0"..., 148) = 148 [pid 385] old_mmap(0x7f600000, 2097152, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_PR IVATE|MAP_ANONYMOUS, -1, 0) = 0x7f600000 [pid 385] mprotect(0x7f600000, 4096, PROT_NONE) = 0 [pid 385] clone(child_stack=0x7f7ffbe0, flags=CLONE_VM|CLONE_FS|CLONE_FILES|CL ONE_SIGHAND|0x21) = 386 [pid 386] getpid() = 386 [pid 386] rt_sigprocmask(SIG_SETMASK, [32], NULL, 16) = 0 [pid 386] rt_sigprocmask(SIG_SETMASK, NULL, [32], 16) = 0 [pid 386] sigsuspend(~[HUP INT QUIT ILL IOT BUS SEGV TSTP] <unfinished ...> [pid 385] kill(383, SIGRT_0) = -1 ESRCH (No such process) [pid 385] poll([{fd=4, events=POLLIN}], 1, 2000) = 0 [pid 385] getppid() = 384 [pid 385] poll( <unfinished ...>
