http://tinkering-is-fun.blogspot.com/2009/12/debugging-non-native- programs-with-qemu.html looks like a plausible tutorial for what you need to do with "file" (and has some other commands that might help for dynamically linked libraries). What you want to do when you get to the SIGABRT is tell gdb "bt" to get a backtrace, which if you have the symbol info will give a backtrace of where the guest was.

When running a compilation of DISTRHO-Ports we get: lv2_ttl_generator: pthread_mutex_lock.c:81: __pthread_mutex_lock: Assertion `mutex->__data.__owner == 0' failed. qemu: uncaught target signal 6 (Aborted) - core dumped ./scripts/generate-ttl.sh: line 27: 16524 Aborted $GEN ./$FILE Makefile:62: recipe for target 'gen_lv2' failed make[1]: *** [gen_lv2] Error 134 make[1]: Leaving directory '/home/pi/zynthian-sw/plugins/DISTRHO-Ports' Makefile:104: recipe for target 'lv2' failed make: *** [lv2] Error 2 lv2_ttl_generator source is here: https://github.com/DISTRHO/DISTRHO-Ports/tree/master/libs/lv2-ttl-generator The command that is ruining is lv2_ttl_generator ./TAL-Filter-2.so And ./TAL-Filter-2.so source is here: https://github.com/DISTRHO/DISTRHO-Ports/tree/master/ports/tal-filter-2/source Is there a way to debug what is going on? This runs fine on a Raspberrypi which is armv7 A workaround would also help. Bug in Zynthian: https://github.com/zynthian/zynthian-sys/issues/59 Bug in DISTRHO-Ports: https://github.com/DISTRHO/DISTRHO-Ports/issues/29 Using qemu-arm-static version from master from two days ago: qemu-arm version 2.12.50 (v2.12.0-1182-ga7a7309ca5-dirty), commit: a7a7309ca52c327c6603d60db90ae4feeae719f7 Also saw this in qemu-arm version 2.12.0 (Debian 1:2.12+dfsg-3) Thanks, Guy To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1776478/+subscriptions
