Hi,
I'm trying to run SageTV, which is a commercial, closed source
linux media server on -current. It is a Java based application
that uses "native" linux JNI libs for accessing video tuner
cards, so unfortunately I must run the Linux JVM, and not
a native JVM.
I've installed the default linux_base-f10, and the
linux-sun-jdk-1.6.0.22.
When I start the application, it semi-works, but the
clients cannot connect. Using kdump && linux-ktrace,
I think I've narrowed the problem to:
9613 java CALL linux_epoll_create
9613 java RET linux_epoll_create -1 errno 78 Function not implemented
9613 java CALL gettimeofday(0x513c9ea0,0)
9613 java RET gettimeofday 0
9613 java CALL gettimeofday(0x513c9eb4,0)
9613 java RET gettimeofday 0
9613 java CALL write(0x4,0x513c7cb0,0x78)
9613 java GIO fd 4 wrote 120 bytes
"Sun 1/16 12:05:57.648 [MiniUIServer@14b5f4a] MiniUI
ServerSocket died from:java.io.IOException: Function not impleme\
nted"
I've done some googling, and it appears that epoll support
was worked on as a SOC project in 2007 by rdivacky. Eg:
http://p4db.freebsd.org/fileLogView.cgi?FSPC=//depot/projects/soc2007/rdivacky/linux_epoll/sys/compat/linux/linux_epoll.c
Were there problems with this code?
AFAIR it's not complete... Roman (CCed)?
Last, is there any workaround to be able to use a linux
jvm? Perhaps by using a different linux base? What
would I be giving up?
Normally it is a combination of linux_base and the sysctl
compat.linux.osrelease. In our kernel there is a difference between
setting osrelease to 2.4 or to 2.6. For the glibc in the linux_base
there _may_ be a difference even in the 3rd number (depends upon how
the glibc is compiled). This can enable/disable some features glibc
tries to use. AFAIR linux_base-f10 needs 2.6.x, IIRC fc6 is the latest
version you can use with 2.4.x.
Bye,
Alexander.
