ICU library libicudata is created with a wrong endianness if the host and target have different endianness. (e.g. build ICU for qemuppc on x86-64 host) See upstream bug report: http://bugs.icu-project.org/trac/ticket/11758 The discussion in oe-core mailing list: https://www.mail-archive.com/openembedded-core@lists.openembedded.org/msg65155.html The root cause is the native pkgdata can not generate correct icu data for different endianness. By default, this data is built into the shared library libicudata that would cause it corrupt. But ICU also provides additional options for loading the data. With option --with-data-packaging=archive, ICU outputs a single icudt.dat file which can be loaded by the library. See document: http://userguide.icu-project.org/icudata So for big endian system, we can use the separated data file which re-generates by icupkg and set the correct ICU_DATA environment variable to make sure the library can load the data without problems.

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.
