cross compiling with meson is easier than the plain makefile build method that libucontext has, there were bunch of problems passing compiler and make variables, compounded by the fact that makefile decided on some compiler flags internally and thought that cflags are synthesized completely in makefile and not passed from environment like OE is doing. As a result some features were not being compiled in e.g. function name aliases were missing meson, on the other hand is cleaner and we have to add a patch to support cpu architecture on meson cmdline, everything else pretty much works out of box (From OE-Core rev: 6e186e75d62e1afabd19a339924b66eac1418274) Signed-off-by: Khem Raj <raj.khem@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.
