    LLVM `llvmSupportHost.h` on C++ MacOS ARM64 does not exist (CMake) - Stack Overflow

    programmeradmin0浏览0评论

    I can't include the llvm/Support/Host.h header in C++ even after specifying:

    find_package(LLVM REQUIRED CONFIG)

include_directories(${LLVM_INCLUDE_DIRS})
add_definitions(${LLVM_DEFINITIONS})

set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -L/opt/homebrew/opt/llvm/lib -Wl,-rpath,/opt/homebrew/opt/llvm/lib -lLLVM")

target_link_libraries(Vast PRIVATE ${LLVM_LIBRARIES})

include_directories(/opt/homebrew/opt/llvm/include)

    Every other header file works just fine, it's just Host.h that is not budging.

    Due to that, or maybe something else, trying to do

    llvm::sys::getDefaultTargetTriple())

    Gives an error, with it complaining that it cannot resolve the symbol getDefaultTargetTriple

    To avoid that I also tried:

    llvm::Triple triple(Module->getTargetTriple());

llvm::outs() << "Target triple: " << triple.str() << "\n";

    Which, gave nothing, it just prints:

    Target triple:

    Is there something I'm missing?

    • Could you post the C++ code that tries to include the header? like #include <llvm/Support/Host.h> – GandhiGandhi Commented Feb 6 at 15:49
    • Also FYi if its "the linker complaining that it cannot resolve the symbol", that means the library containing that symbol isn't linked against the binary. llvm is split into a few libraries, and that symbols is included in the "support" library. I'd be suspicious of what LLVM_LIBRARIES contains; I don't see it set. – GandhiGandhi Commented Feb 6 at 15:59
    • @GandhiGandhi Complete mishap on my part. the #include is just that, #include "llvm/Support/Host.h" and the error has been added to the question – Silicon Commented Feb 6 at 16:11
    • Next time that could be relevant info. Including with quotes " has slightly different file lookup rules than including with angle bracket <> – GandhiGandhi Commented Feb 7 at 16:21

    Reset to default 0

    Back, 5 hours later that is. Turns out the answer is that Host.h is not located within llvm/Support, but instead llvm/TargetParser/Host.h, and with that, you can use the llvm::sys::getDefaultTargetTriple().
