Next, if I set MACOSX_DEPLOYMENT_TARGET="11.0" in ~/.profile, bootstrap fails:

    configure:3441: checking whether the C compiler works
    configure:3463: gcc -isysroot /nonexistent    conftest.c  >&5
    clang: warning: no such sysroot directory: '/nonexistent' [-Wmissing-sysroot]
    ld: library 'System' not found
    clang: error: linker command failed with exit code 1 (use -v to see invocation)
    configure:3467: $? = 1

see log here:

https://github.com/mansourmoufid/pkgsrc-macos-test/actions/runs/16911956796/job/47915741117

So I unset MACOSX_DEPLOYMENT_TARGET just before bootstrapping.

(MACOSX_DEPLOYMENT_TARGET is not the same thing as the SDK version, it's the equivalent of clang's -mmacos-version-min. See here: https://clang.llvm.org/docs/CommandGuide/clang.html#envvar-MACOSX_DEPLOYMENT_TARGET )

The bootstrap is successful, but then building any package fails with:

    ERROR: This package has set PKG_FAIL_REASON:
    ERROR: Unable to find macOS SDK at /nonexistent
    ERROR: Check MACOSX_DEPLOYMENT_TARGET points to a valid SDK

see log here:

https://github.com/mansourmoufid/pkgsrc-macos-test/actions/runs/16912926065/job/47919232854

So I define the OSX_SDK_PATH variable in mk.conf:

    .if ${OPSYS} == "Darwin"
    SDKROOT!=                      xcrun --sdk macosx --show-sdk-path
    OSX_SDK_PATH=                  ${SDKROOT}
    .endif
