[YOCTO #12791] According to struct elf32_hd, the e_shnum is section header number, and the index is e_shstrndx, not e_shnum. This can fix segmention fault when handle libqb.so.0.18.2 from libqb_1.0.3. It fails to handle libqb.so.0.18.2 and get errors: Symbol section index outside of section numbers Then segmentation fault, this is because the e_shnum is 34, while e_shstrndx is 27 (it would be 33 when no errors), I've checked several elf files to confirm that the ones after e_shstrndx is NULL, so use e_shstrndx should be correct. Fixed: MACHINE="qemux86-64" IMAGE_INSTALL_append = " libqb" #libqp is from meta-openembedded $ bitbake core-image-minimal Segmention fault (From OE-Core rev: b7c291ee6532cba845ee6bfbbaa21076a2b2cbe5) Signed-off-by: Robert Yang <liezhi.yang@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
