You probably need to set QEMU_EXTRAOPTIONS, ideally in the BSP. See qemu.bbclass and meta-intel for examples. 66332 2 richard.purdie 2016-09-19 16:26:15 +0000 Talking with Otavio, this has the e5500 64 bit processor so its probably using the wrong system qemu and the wrong cpu option as far as I can tell. 66335 3 otavio 2016-09-19 18:59:02 +0000 I played with it a little and got it using the right params however it still fails badly. | /home/otavio/src/yocto/build/tmp/work/ppce6500-oel-linux/gobject-introspection/1.48.0-r0/build/tmp-introspectyx4v7knq/GLib-2.0: Invalid ELF image for this architecture | If the above error message is about missing .so libraries, then setting up GIR_EXTRA_LIBS_PATH in the recipe should help. | (typically like this: GIR_EXTRA_LIBS_PATH="${B}/something/.libs" ) | Command '['/home/otavio/src/yocto/build/tmp/work/ppce6500-oel-linux/gobject-introspection/1.48.0-r0/build/g-ir-scanner-qemuwrapper', '/home/otavio/src/yocto/build/tmp/work/ppce6500-oel-linux/gobject-introspection/1.48.0-r0/build/tmp-introspectyx4v7knq/GLib-2.0', '--introspect-dump=/home/otavio/src/yocto/build/tmp/work/ppce6500-oel-linux/gobject-introspection/1.48.0-r0/build/tmp-introspectyx4v7knq/functions.txt,/home/otavio/src/yocto/build/tmp/work/ppce6500-oel-linux/gobject-introspection/1.48.0-r0/build/tmp-introspectyx4v7knq/dump.xml']' returned non-zero exit status 1 | Makefile:3518: recipe for target 'GLib-2.0.gir' failed | make[2]: *** [GLib-2.0.gir] Error 1 66364 4 ross.burton 2016-09-20 16:07:29 +0000 "Invalid ELF image for this architecture" I'm guessing that is from qemu, so can you verify that the binaries are the right type. Maybe there's a bug in qemu's ELF parser? 66412 5 otavio 2016-09-21 11:36:22 +0000 I found that the e5500 is provided by the QEMU PPC64 emulation and it turns to need to use the 32bit ABI for calling (using the qemu-ppc64abi32). However, even doing so, it fails: | qemu: uncaught target signal 4 (Illegal instruction) - core dumped | Illegal instruction (core dumped) So my guess is that the generated code is indeed invalid. 88467 6 akuster808 2020-10-22 08:27:01 +0000 Is this being seen on current Master (3.2) ? 94282 7 randy.macleod 2022-10-27 15:27:14 +0000 Won't fix, so long ppc...
