perl-cross is a build system overlay from buildroot project that aims to bring a bit of sanity to cross-building perl. The advantage of using that is that we can drop a lot of custom patches (that no one really understands), and simplify the perl recipe as well. Also the build time goes down from several minutes to about 30 seconds. The whole thing becomes maintainable again, in my opinion. When rewriting the recipe I had two goals in mind: 1. Stay with upstream defaults as much as possible 2. Add custom patches only when their necessity was proven through testing. http://arsv.github.io/perl-cross/ (From OE-Core rev: 52f2828314f851263ca3a6beb41ec936fab4d3ab) Signed-off-by: Alexander Kanavin <alex.kanavin@gmail.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.
