A recent commit in GLIBC [1] got rid of _LIB_VERSION, which makes Perl's build fail: | pp.c:47:5: error: unknown type name '_LIB_VERSION_TYPE'; did you mean '__VERSION__'? | _LIB_VERSION_TYPE _LIB_VERSION = _IEEE_; | ^~~~~~~~~~~~~~~~~ | __VERSION__ | pp.c:47:38: error: '_IEEE_' undeclared here (not in a function); did you mean '_SIZET_'? | _LIB_VERSION_TYPE _LIB_VERSION = _IEEE_; | ^~~~~~ | _SIZET_ | make[1]: *** [pp.o] Error 1 The current config.sh enables d_libm_lib_version for everyone, with special cases left to undefine it as fixup (such as MUSL [2]). Since this may only affect some BSDs and Cygwin [3], it follows that the opposite (defining it) should be a fixup for those special cases.

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.
