Hi there,
I've been trying to compile and use the multimedia/transcode package. It
does not work, because it never exits: e.g "transcode -h" gives the help
message and then stalls forever.
A ktrace reveals this:
444 1 transcode RET write 40/0x28
444 1 transcode CALL write(1,0x80a3000,0x23)
444 1 transcode GIO fd 1 wrote 35 bytes
" -v print version
"
444 1 transcode RET write 35/0x23
444 1 transcode CALL write(1,0x80a3000,1)
444 1 transcode GIO fd 1 wrote 1 bytes
"
"
444 1 transcode RET write 1
444 1 transcode CALL _lwp_wakeup(2)
444 1 transcode RET _lwp_wakeup 0
444 2 transcode RET __sigtimedwait -1 errno 87 Operation Canceled
444 2 transcode CALL __sigtimedwait(0x8095ff0,0xbb7fff2c,0)
444 2 transcode RET __sigtimedwait -1 errno 87 Operation Canceled
444 2 transcode CALL __sigtimedwait(0x8095ff0,0xbb7fff2c,0)
444 1 transcode CALL _lwp_wait(2,0xbfbfd818)
444 2 transcode RET __sigtimedwait 0
444 2 transcode CALL write(2,0xbb7ff7e0,0x2a)
444 2 transcode GIO fd 2 wrote 42 bytes
"
[transcode] (sighandler) SIGINT received
"
It seems that _lwp_wakeup fails in some way therefore I was wondering if
this has to do with the recent changes to libpthread.
TIA,
Vincent
