Hi, I'm currently trying to port OpenJDK7 (ie. icedtea) to Debian GNU/kFreeBSD [1]. Debian GNU/kFreeBSD is a port that consists of GNU userland using the GNU C library on top of FreeBSD kernel with classic Debian package management software :) There is in fact two ports : kfreebsd-i386 and kfreebsd-amd64. My current WiP patch [2] consist mostly in : - Alter build system to consider GNU/kFreeBSD like mostly linux (ie. add many ifdef __GLIBC__) - Steal BSD network stack impl for bsd-port hg repository - Use sysctl call instead of sysinfo() - Disable build of alsa and sctp I'm able to compile a stage1 jdk (openjdk-boot) but first invocation of this jdk (with ZeroVM of course) just fail badly : # # A fatal error has been detected by the Java Runtime Environment: # # Internal Error (os_linux_zero.cpp:260), pid=96754, tid=1026 # fatal error: caught unhandled signal 11 # # JRE version: 7.0_136-b136 # Java VM: OpenJDK Zero VM (21.0-b07 interpreted mode linux-i386 ) # Derivative: IcedTea7 2.0pre # Distribution: Debian GNU/kFreeBSD unstable (sid), package 7~b136-2.0~pre1-3 I've attached hs_err_pid96754.log and put a GDB output online [3] => Did someone have a clue about this issue ? Or maybe a process to track down this segv signal ? PS: Please keep debian-bsd@l.d.o and 567992@b.d.o in CC.
