The alternative ld.so patch is set up so the linker will search the nativesdk sysroot before searching the host filesystem. However the patch concatenates <sysroot>/etc and /etc/ld.so.conf leading to a path that does not exist: 3061991 openat(AT_FDCWD, "/buildtools/sysroots/x86_64-pokysdk-linux/etc/etc/ld.so.conf", O_RDONLY) = -1 ENOENT (No such file or directory) In native-nspr, the build uses -lpthread, which triggers a search for librt, but because of the above it drags in the system librt leading to errors as follows: /buildtools/sysroots/x86_64-pokysdk-linux/usr/lib/gcc/x86_64-pokysdk-linux/ 9.3.0/../../../../x86_64-pokysdk-linux/bin/ld: /lib64/librt.so.1: undefined reference to `__clock_getcpuclockid@GLIBC_PRIVATE' update concatenation to correctly construct the path to the nativesdk ld.so.conf [YOCTO #13853] (From OE-Core rev: d085da8300abb72e14957ecedf40189b25088d4b) Signed-off-by: Jeremy Puhlman <jpuhlman@mvista.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.
