Hi Team, I am trying to build toolchain with AARCH64/ARM32 multilib support.
My configuration part of toolchain is as follows: == DEFAULTTUNE = "cortexa72" require conf/machine/include/arm/armv8a/tune-cortexa72.inc # multilib support require conf/multilib.conf MULTILIBS = "multilib:lib32" DEFAULTTUNE:virtclass-multilib-lib32 = "armv7athf-neon" == With this when I tried to build "meta-toolchain", if fails with following error messages: == | ../../../../../../../../../work-shared/gcc-11.4.0-r0/gcc-11.4.0/libsanitizer/sanitizer_common/sanitizer_li nux.cpp: In fu nction '__sanitizer::uptr __sanitizer::GetKernelAreaSize()': | ../../../../../../../../../work-shared/gcc-11.4.0-r0/gcc-11.4.0/libsanitizer/sanitizer_common/sanitizer_linux.cpp:1024:1 : error: r7 cannot be used in 'asm' here | 1024 | } | | ^ *| ../../../../../../../../../work-shared/gcc-11.4.0-r0/gcc-11.4.0/libsanitizer/sanitizer_common/sanitizer_linux.cpp:1024:1: error: r7 cannot be used in 'asm' here* | make[2]: Leaving directory '/b/workspace/yocto/build/tmp/work/armv7at2hf-neon-pokymllib32-linux-gnueabi/lib32-gcc-sanitizers/11.4.0-r0/gcc-11.4.0/build.arm-pokymllib32-linux-gnueabi.arm-pokymllib32-linux-gnueabi/arm-pokymllib32-linux-gnueabi/libsanitizer/sanitizer_common' | make[2]: *** [Makefile:617: sanitizer_linux.lo] Error 1 | make[1]: Leaving directory '/b/workspace/yocto/build/tmp/work/armv7at2hf-neon-pokymllib32-linux-gnueabi/lib32-gcc-sanitizers/11.4.0-r0/gcc-11.4.0/build.arm-pokymllib32-linux-gnueabi.arm-pokymllib32-linux-gnueabi/arm-pokymllib32-linux-gnueabi/libsanitizer' | make[1]: *** [Makefile:531: all-recursive] Error 1 | make: *** [Makefile:418: all] Error 2 | ERROR: oe_runmake failed == Is this a known issue? Is multilib supported for ARM64/32 combination? Or do I need to use seperate machine/toolchain configuration for ARM32 build? Regards, Gaurang Shastri
