I'm trying to copy the ios build.sh example usage to use for tvos and I've gotten pretty far, but need some help here:

Basically, I stripped out the same parts of the Xcode.xip for AppleTVOS that I stripped out for iPhoneOS and then made adjustments to the ios_toolchain/build.sh for tvos. It looks like I got pretty far, but maybe I deluding myself.

Also, it appears that the wrapper.c needs adjustment:

    env(&sdk, "IOS_SDK_SYSROOT", sdkpath);
    env(&cpu, "IOS_TARGET_CPU", TARGET_CPU);

    env(&osmin, "IPHONEOS_DEPLOYMENT_TARGET", OS_VER_MIN);
    unsetenv("IPHONEOS_DEPLOYMENT_TARGET");

    snprintf(osvermin, sizeof(osvermin), "-miphoneos-version-min=%s", osmin);

Would it work if I just change those values to APPLETVOS|appletvos?

Finally, I just noticed this at the bottom of my build.sh execution:

*** checking toolchain ***
clang-12: warning: using sysroot for 'AppleTVOS' but targeting 'iPhone' [-Wincompatible-sysroot]
/usr/bin/ld: unrecognized option '-dynamic'
/usr/bin/ld: use the --help option for usage information
clang-12: error: linker command failed with exit code 1 (use -v to see invocation)

I assumed this is coming from this line in build.sh:

echo "int main(){return 0;}" | $TRIPLE-clang -xc -O2 -o test - 1>/dev/null || exit 1

I can't reproduce the variable-sized error. I have tested clang 3.5, 3.6, 3.7, 3.8, 3.9, 4.0.1, 5.0.2, 6.0.1, 7.0.1, 8.0.0, 9.0.0, 10.0.0, 11.0.0, and git ...

What's your OS and your compiler version?

It's -mtvos-version-min=x.x, I think.

I'm very sorry for not getting back to you sooner.

I'm using Apple's llvm https://github.com/apple/llvm-project.git rev
8b8cdf9a9dc095e53269eaf5acfd803ee28c9083

I build it, then build a new version of it with the just built version (so llvm with llvm)

    mkdir llddir && cd lldir &&\
    git init &&\
    git remote add origin https://github.com/apple/llvm-project.git &&\
    git fetch origin 8b8cdf9a9dc095e53269eaf5acfd803ee28c9083 &&\
    git reset --hard FETCH_HEAD && \
    mkdir -p llvm/build clang/build1 clang/build2 &&\
    cd llvm/build &&\
    cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_BUILD_TYPE=Release \
      -DLLVM_ENABLE_ASSERTIONS=OFF -DLLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN=1 &&\
    make -j$(nproc --all) install &&\
    cd ${LLDIR}/clang/build1 &&\
    cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_BUILD_TYPE=Release \
      -DLLVM_ENABLE_ASSERTIONS=OFF -DLLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN=1 &&\
    make -j$(nproc --all) clang &&\
    cd ../build2 &&\
    CC=${LLDIR}/clang/build1/bin/clang CXX=${LLDIR}/clang/build1/bin/clang++ \
      cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local -DCMAKE_BUILD_TYPE=Release \
      -DLLVM_ENABLE_ASSERTIONS=OFF -DLLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN=1 &&\
    make -j$(nproc --all) install &&\

The OS is Debian buster-20201209-slim and I start out with g++ and llvm-dev installed via apt. I use the above llvm build with my ios (cctools-port) and mac (osxcross) builds too and it has worked fine.

Thank you, sir.

Pulling in your patch 14ab64360c and changing -miphoneos-version-min to -mtvos-version-min has me building successfully.
