I'm starting Tier-2 builds for this architecture and have found that jemalloc is not happy with this target. It might be related, but I'm unsure. http://tasty.ysv.freebsd.org/build.html?mastername=11arm-default&build=2015-11-01_18h49m25s Specifically, I see a failure patten in jemalloc that yeilds error messages like: <jemalloc>: /usr/local/poudriere/jails/11arm/usr/src/lib/libc/../../contrib/jemalloc/include/jemalloc/internal/arena.h:715: Failed assertion: "binind < NBINS || binind == BININD_INVALID" or <jemalloc>: /usr/local/poudriere/jails/11arm/usr/src/lib/libc/../../contrib/jemalloc/include/jemalloc/internal/arena.h:1217: Failed assertion: "arena_mapbits_allocated_get(chunk, pageind) != 0" These builds are done via the newly implemented qemu-user-static support for armv4/5, so it may be related to something unimplemented. But I haven't dug into this any further. sean > >> >> since CLANG was upgraded to 3.7 I'm not abel to compile anything >> on my Dreamplug anymore: >> >> FreeBSD clang version 3.7.0 (tags/RELEASE_370/final 246257) >> 20150906 Target: arm--freebsd11.0-gnueabi Thread model: posix >> configure:3562: $? = 0 configure:3551: cc -v >&5 FreeBSD clang >> version 3.7.0 (tags/RELEASE_370/final 246257) 20150906 Target: >> arm--freebsd11.0-gnueabi Thread model: posix configure:3562: $? = >> 0 configure:3551: cc -V >&5 cc: error: argument to '-V' is >> missing (expected 1 value) cc: error: no input files >> configure:3562: $? = 1 configure:3551: cc -qversion >&5 cc: >> error: unknown argument: '-qversion' cc: error: no input files >> configure:3562: $? = 1 configure:3582: checking whether the C >> compiler works configure:3604: cc conftest.c >&5 cc: error: >> unable to execute command: Bus error (core dumped) cc: error: >> clang frontend command failed due to signal (use -v to see >> invocation) >> >> Unfortunately I don't have any debugging symbols enabled in world >> (yet - it's compiling), only in the kernel, so I can't get a >> proper backtrace: >> >> root@dreamplug:~ # gdb /usr/bin/cc cc.core GNU gdb 6.1.1 >> [FreeBSD] Copyright 2004 Free Software Foundation, Inc.
