LD_LIBRARY_PATH leaks into host executables too, and breaks them as they are not uninative-enabled. E.g. on ubuntu 18.04 trying to run host bash with a sysroot that was built on Fedora 33: akanavin@ubuntu1804-ty-3:/home/pokybuild/yocto-worker/oe-selftest-ubuntu/build/build-st-24341/tmp/work/x86_64-linux/gnupg-native/2.3.1-r0/recipe-sysroot-native$ LD_LIBRARY_PATH=./usr/lib /bin/bash /bin/bash: ./usr/lib/libtinfo.so.5: no version information available (required by /bin/bash) /bin/bash: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.33' not found (required by ./usr/lib/libtinfo.so.5) This was seen e.g. here: https://autobuilder.yoctoproject.org/typhoon/#/builders/87/builds/2090/steps/14/logs/stdio (From OE-Core rev: 0e9850486b74a3de934527ca1077df001d3a8d22) 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.
