@am11 I think this is related to #62486, could you, please, take a look?

[am11]

@gbalykov, yup related to #62486 which fixed armel build but that is not cause of this error on arm64. 🙂

Can you please get some more diagnostics about the failing target:

./build.sh libs.tests -v:diag ...other args... | grep -A10 -E 'DnneCompilerCommand|GetUnixBuildArgumentsForDNNE'

basically we want to see the compiler command. (previously, I had to use similar debugging method for this target with DNNE sources to understand how the command is used in DNNE repo for gcc support: #60757)

I see that it can't find clang10 for some reason, but build of native part is performed with it:

OK, it was not a straightforward one, but I am getting somewhere. First we are missing arm64 tizen tag in containers list, so I built tizen-arm64 rootfs in armel container (which also required patching objcopy in cmake).

Here is the command DNNE's internal target executes:

"/usr/bin/clang-9" -O2 -shared -fpic -D DNNE_ASSEMBLY_NAME=Microsoft.Interop.Tests.NativeExports -D DNNE_COMPILE_AS_SOURCE -I "/root/.nuget/packages/dnne/1.0.27/tools/platform" -I "/root/.nuget/packages/microsoft.netcore.app.host.linux-arm64/6.0.0-rc.1.21411.2/runtimes/linux-arm64/native" -o "/runtime/artifacts/obj/NativeExports/net7.0-Release/linux-arm64/dnne/bin/Microsoft.Interop.Tests.NativeExportsNE.so" --target=aarch64-linux-gnu --gcc-toolchain=/runtime/.tools/rootfs/arm64/usr --sysroot=/runtime/.tools/rootfs/arm64 "/runtime/artifacts/obj/NativeExports/net7.0-Release/linux-arm64/dnne/Microsoft.Interop.Tests.NativeExports.g.c" "/root/.nuget/packages/dnne/1.0.27/tools/platform/platform.c" -lstdc++ "/root/.nuget/packages/microsoft.netcore.app.host.linux-arm64/6.0.0-rc.1.21411.2/runtimes/linux-arm64/native/libnethost.a" --target=aarch64-linux-gnu --gcc-toolchain=/runtime/.tools/rootfs/arm64/usr --sysroot=/runtime/.tools/rootfs/arm64 -Wl,--rpath-link=/runtime/.tools/rootfs/arm64/lib/aarch64-linux-gnu -Wl,--rpath-link=/runtime/.tools/rootfs/arm64/usr/lib/aarch64-linux-gnu

which resulted in:

/usr/bin/ld: unrecognised emulation mode: aarch64linux
Supported emulations: elf_x86_64 elf32_x86_64 elf_i386 elf_iamcu i386linux elf_l1om elf_k1om i386pep i386pe

I think you are on a different environment with clang10 with more than just the rootfs setup, so could be a different error? Could you share the dockerfile or details how your environment is setup, so I can dig deeper?

[am11]

No usable version of clang10 found.

Yup, just drop -clang10 from the command line it will pick it up automagically. If that fixes the build, I can look into why the detection is failing when -clang10 is passed.

[gbalykov]

I use next setup for tizen cross build in docker.

Next script creates ubuntu docker container:

sudo docker pull ubuntu:focal
sudo docker run ubuntu:focal bin/bash -c "apt update; DEBIAN_FRONTEND=noninteractive apt -y install tzdata; apt -y install git sudo curl libxml2-utils rpm2cpio cpio clang-9 llvm-9 clang-10 llvm-10 gcc-arm-linux-gnueabi g++-arm-linux-gnueabi gcc-arm-linux-gnueabihf g++-arm-linux-gnueabihf gcc-aarch64-linux-gnu g++-aarch64-linux-gnu vim cmake liblttng-ust-dev locales libicu-dev zlib1g zlib1g-dev libkrb5-dev libssl-dev; locale-gen en_US.UTF-8"

To build rootfs:

./eng/common/cross/build-rootfs.sh arm64 tizen

To cross build runtime in ubuntu docker container:

ROOTFS_DIR=`pwd`/.tools/rootfs/arm64 ./build.sh --portablebuild false --cross  --arch arm64 --runtimeConfiguration Release --librariesConfiguration Release --subset clr+libs.native /p:EnableSourceLink=false
ROOTFS_DIR=`pwd`/.tools/rootfs/arm64 ./build.sh --cross --arch arm64 --runtimeConfiguration Release --librariesConfiguration Release --subset libs.ref+libs.src+libs.pretest+libs.packages+libs.tests --testscope all /p:EnableSourceLink=false

Yup, just drop -clang10 from the command line

This leads to another error:

  Building native export: "/usr/bin/clang-10" -O2 -shared -fpic -D DNNE_ASSEMBLY_NAME=Microsoft.Interop.Tests.NativeExports -D DNNE_COMPILE_AS_SOURCE -I "/home/runtime/.packages/dnne/1.0.27/tools/platform" -I "/home/runtime/.packages/microsoft.netcore.app.host.linux-arm64/6.0.0-rc.1.21411.2/runtimes/linux-arm64/native" -o "/home/runtime/artifacts/obj/NativeExports/net7.0-Release/linux-arm64/dnne/bin/Microsoft.Interop.Tests.NativeExportsNE.so" --target=aarch64-linux-gnu --gcc-toolchain=/home/runtime/.tools/rootfs/arm64/usr --sysroot=/home/runtime/.tools/rootfs/arm64  "/home/runtime/artifacts/obj/NativeExports/net7.0-Release/linux-arm64/dnne/Microsoft.Interop.Tests.NativeExports.g.c" "/home/runtime/.packages/dnne/1.0.27/tools/platform/platform.c" -lstdc++ "/home/runtime/.packages/microsoft.netcore.app.host.linux-arm64/6.0.0-rc.1.21411.2/runtimes/linux-arm64/native/libnethost.a" --target=aarch64-linux-gnu --gcc-toolchain=/home/runtime/.tools/rootfs/arm64/usr --sysroot=/home/runtime/.tools/rootfs/arm64  -Wl,--rpath-link=/home/runtime/.tools/rootfs/arm64/lib/aarch64-linux-gnu -Wl,--rpath-link=/home/runtime/.tools/rootfs/arm64/usr/lib/aarch64-linux-gnu 
  /usr/bin/aarch64-linux-gnu-ld: cannot find crtbeginS.o: No such file or directory
  /usr/bin/aarch64-linux-gnu-ld: cannot find -lgcc

I see that linker flags are setup in a way, that is not correct for tizen. In eng/common/cross/toolchain.cmake we setup linker flags this way:

    add_toolchain_linker_flag("-B${CROSS_ROOTFS}/usr/lib64/gcc/${TIZEN_TOOLCHAIN}")
    add_toolchain_linker_flag("-L${CROSS_ROOTFS}/lib64")
    add_toolchain_linker_flag("-L${CROSS_ROOTFS}/usr/lib64")
    add_toolchain_linker_flag("-L${CROSS_ROOTFS}/usr/lib64/gcc/${TIZEN_TOOLCHAIN}")

    add_toolchain_linker_flag("-Wl,--rpath-link=${CROSS_ROOTFS}/lib64")
    add_toolchain_linker_flag("-Wl,--rpath-link=${CROSS_ROOTFS}/usr/lib64")
    add_toolchain_linker_flag("-Wl,--rpath-link=${CROSS_ROOTFS}/usr/lib64/gcc/${TIZEN_TOOLCHAIN}")

[am11]

Thanks. Regarding -clang10 detection, we used same mechanism in DNNE as used by mono.proj. Unfortunately, both are missing version parsing as we do

runtime/eng/native/build-commons.sh

Line 311 in 0b17270

__CompilerMajorVersion="${parts[0]}"

(and below for gcc). I will first fix that.

@am11 that's strange. Do you have checked build of dotnet sdk? Release dotnet should not show any asserts. For me this works:

[am11]

You are right about the strange build. I just pushed the "remaining argument" index update ("${@:7}" -> "${@:5}") in #63126 which settles the build flavor. Now the tizen arm64 build is progressing fine, locally. 👍

[am11]

@gbalykov, please try this patch: http://sprunge.us/2kg036

curl -s http://sprunge.us/2kg036 | git apply -

and build libs.tests subset as you normally do with additional __DistroRid=tizen.7.0.0-arm64 environment variable. It's working on my machine ™️ :)

note: I haven't added a support for BEFORE and AFTER keywords in this polyfill macro, since we are currently not using it in toolchain.cmake
