VLC run on arm bug:can't creat thread(Operation not permit)
Posted: 19 Mar 2010 04:06
hi pal,
I have try to cross compile vlc and run it on arm, I already successfully cross compile it(use uclibc, I'm not sure wther it cause the problem). But when I run it , problems come:
it seems the vlc can not create the thread, so I check the source code, I find following:
VLC use attr struct to create new thread , and change the stacksize,
If I change the code as this
the vlc can run , but it will quit automaticlly without any error. maybe it has relationship whit the thread.......
and plus, I write a threadtest.c file use following code to create thread and it success
I confused.....I doubt that VLC has any user permission to run the program just as create thead? cause VLC can not run with root. Maybe my board have a wrong user permission
