one of the build steps ruby has is that it generated rb_mjit_header.h during configure using gcc preprocessor using -dD which emits built-in defines as well, problem happens when this header is later included in subsequent compiles, where compiler errors out stating that an existing internal define is redefined | /tmp/20200123-2021083-2c601q.h:13849:9: error: "__has_include" cannot be used as a macro name | 13849 | #define __has_include __has_include | | ^~~~~~~~~~~~~ | compilation terminated due to -Wfatal-errors. Since compiler already will take care of it internally we can edit it out from this header file (From OE-Core rev: b4f0df9a0e998af746bcd84cb81ea4ba0107f989) 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.
