Hi There, Following the instruction from TI
https://software-dl.ti.com/processor-sdk-linux-rt/esd/AM64X/latest/exports/docs/linux/Overview_Building_the_SDK.html I've successfully set up a yocto project for the AM64x. Toolchain used is 9.2-2019.12 Now I need to add support for multilib32 because I have some software that can be compiled only 32 bit. I added the following lines to conf/local.conf # Define multilib target require conf/multilib.conf MULTILIBS = "multilib:lib32" DEFAULTTUNE_virtclass-multilib-lib32 = "armv7athf-neon" And I am able to build a few packages with lib32- successfully, however, lib32-libtool-cross fails at the configure stage: --host is set to the value armmllib32-linux-gnueabi ERROR: lib32-libtool-cross-2.4.6-r0 do_configure: configure failed ERROR: lib32-libtool-cross-2.4.6-r0 do_configure: Execution of '/home/build/tisdk/build/arago-tmp-external-arm-glibc/work/armv7at2hf-neonmllib32-linux-gnueabi/lib32-libtool-cross/2.4.6-r0/temp/run.do_configure.29261' failed with exit code 1: automake (GNU automake) 1.16.1 Copyright (C) 2018 Free Software Foundation, Inc.

Manually running the configure command with -host=arm-none-linux-gnueabihf is working properly. Following suggestion by Richard Purdie https://lists.yoctoproject.org/g/poky/message/12535 Adding TARGET_VENDOR = "-oe" To conf/local.conf didn't do the trick. So I modified sources/meta-arago/meta-arago-distro/conf/distro/include/toolchain-arm.inc -TARGET_VENDOR = "" +TARGET_VENDOR = "-oe" And then bitbake lib32-libtool-cross finished successfully, but when trying to build the entire image libtool-cross failed with ## ------------------------- ## ## Configuring libtool 2.4.6 ## ## ------------------------- ## checking for GNU M4 that supports accurate traces... /home/build/tisdk/build/arago-tmp-external-arm-glibc/work/aarch64-oe-linux/libtool-cross/2.4.6-r0/recipe-sysroot-native/usr/bin/m4 checking whether /home/build/tisdk/build/arago-tmp-external-arm-glibc/work/aarch64-oe-linux/libtool-cross/2.4.6-r0/recipe-sysroot-native/usr/bin/m4 accepts --gnu... yes checking how m4 supports trace files... --debugfile checking for a BSD-compatible install... /home/build/tisdk/build/arago-tmp-external-arm-glibc/hosttools/install -c checking whether build environment is sane... yes checking for aarch64-oe-linux-strip... aarch64-none-linux-gnu-strip checking for a thread-safe mkdir -p... /home/build/tisdk/build/arago-tmp-external-arm-glibc/hosttools/mkdir -p checking for gawk... gawk checking whether make sets $(MAKE)... yes checking whether make supports nested variables... yes checking whether make supports nested variables...

I suspect it will come up in other packages as well. Thanks a lot, Nir.
