Hello Chris, Please see my inline comments.
Best Regards, Zhenhua From: yocto-boun...@yoctoproject.org [mailto:yocto-boun...@yoctoproject.org] On Behalf Of Chris Trobridge Sent: Monday, April 25, 2016 11:01 PM To: yocto@yoctoproject.org Subject: Re: [yocto] [Fwd: gobject introspection release notes] Any ideas as to why "qemu-ppc64 crashes out immediately"? I can confirm the build ends in a segfault when I tried building gobject-introspection for the t1042d4rdb-64b machine. [Luo Zhenhua-B19537] This is a gobject-introspection support issue of QEMU PPC64, the fix is not available now, you can use the following workaround to bypass the issue. http://git.yoctoproject.org/cgit.cgi/meta-fsl-ppc/tree/README#n18 I did get one qemu crash recorded by Fedora but the actual crash dumps (appended) are for a PowerPC. That said, given the dump, either the processor got nowhere or they are likely corrupt. The invalid access reported is roughly to the stack but with the upper 32-bits zeroed. If I configure bitbake for a 32-bit build (t1042d4rdb) then the build fails with "Unable to find CPU definition" (cpu e5500) so a 32-bit build is out of the question too. The command line from the wrapper is: PSEUDO_UNLOAD=1 qemu-ppc -r 2.6.32 -cpu e5500 -L /home/chris/yocto/build/tmp/sysroots/t1042d4rdb -E LD_LIBRARY_PATH=$GIR_EXTRA_LIBS_PATH:.libs:/home/chris/yocto/build/tmp/sysroots/t1042d4rdb//usr/lib:/home/chris/yocto/build/tmp/sysroots/t1042d4rdb//lib "$@" [Luo Zhenhua-B19537] Please fetch the latest commit, the issue is fixed by http://git.yoctoproject.org/cgit.cgi/poky/commit/?h=krogoth&id=27e202f2d9114a64b67c83eb7eafeb12de5ceea7. The cpu is supported by the fedora qemu-ppc64, but not qemu-ppc - ie it's a 64-bit processor that's not supported in 32-bit mode. This is not massively urgent for me but it may be important in the future and I am curious as to whether the problem is in the qemu emulation or in the emulated code.
