Is there a tutorial about aie environment configuration?

Hi, I'm new to this project, and I have some troubles when compiling aie.cpp. Could you kindly tell me a tutorial or how to configure the relevant environment about aie especially the header and libraries path?

Hi and welcome!
Which aie.cpp are you referring to exactly? Are you trying to build LLVM? You need to configure the build using cmake, and then use ninja/make to build. Some minimal cmake configuration could look like:

mkdir build;
cd build;
cmake -G Ninja -C ../clang/cmake/caches/Peano-AIE.cmake ../llvm

You can then build clang using ninja clang.
I hope this helps!

I have successfully built the project. However, I don't know how to correctly compile the cpp file, since I'm confused about the including path to support AIE Intrinsic API. It should use the environment of Vitis? Could you kindly tell me how to configure the include and library environment? Thanks.

Hello,
I'm also getting troubles to compile a simple cpp file with the AIE API headers. My cpp file is simply:

#include <iostream>
#include <cstring>
#include <aie_api/aie.hpp>

using namespace aie;

int main() {

    if(arch::is(arch::AIE)) {
        std::cout << "Running on AIE\n";
    } else if(arch::is(arch::AIE_ML)) {
        std::cout << "Running on AIE-ML\n";
    }

   return 0;
}

The error Im getting is: error: ‘arch’ has not been declared

For the environement: Im using a Ryzen AI 7 with XDNA 1 (AIE-ML) NPU architecture on an Ubuntu 24.04 with a fresh XRT installation that perfectly works.

my cmakelist file is

cmake_minimum_required(VERSION 3.15...3.31)

project(AMD_NPU VERSION 1.0
                DESCRIPTION "C++ Access to NPU using XRT with XDNA drivers"
                LANGUAGES C CXX)

# Required Projects
find_package(XRT REQUIRED)

# Find XRT and AIE API
set(XRT_INCLUDE_DIR "/opt/xilinx/xrt/include")
set(XRT_LIB_DIR "/opt/xilinx/xrt/lib")

# Test
add_executable(test src/test.cpp)

# Include XRT headers
target_include_directories(test PRIVATE ${XRT_INCLUDE_DIR} ${CMAKE_SOURCE_DIR}/include)

# Link against XRT libraries$
target_link_directories(test PRIVATE ${XRT_LIB_DIR})
target_link_libraries(test PRIVATE xrt_coreutil xrt++)

My general problem is that I don't get if I should use Vitis or not with this API. My toolchain (MLIE-AIE) says no, but it seems that the AIE_ARCH cannot be defined without AIE tools.

Thanks.
