    @SGaist Hi,

    This is my CMakeLists.txt

    cmake_minimum_required(VERSION 3.16)

project(BLETester VERSION 1.1 LANGUAGES CXX)

set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_VERBOSE_MAKEFILE ON)

find_package(Qt6 6.4 REQUIRED COMPONENTS Quick Bluetooth Positioning Location Widgets)

qt_standard_project_setup()

qt_add_executable(BLETester
    main.cpp
    mainwindow.cpp
    bleinterface.cpp
    mainwindow.h
    bleinterface.h
    characteristicinfo.cpp characteristicinfo.h
    aes.c aes.h aes.hpp
)

set_target_properties(BLETester PROPERTIES
    MACOSX_BUNDLE_GUI_IDENTIFIER my.example.com
    MACOSX_BUNDLE_BUNDLE_VERSION ${PROJECT_VERSION}
    MACOSX_BUNDLE_SHORT_VERSION_STRING ${PROJECT_VERSION_MAJOR}.${PROJECT_VERSION_MINOR}
    MACOSX_BUNDLE TRUE
    WIN32_EXECUTABLE TRUE
)

if (APPLE)
    if (IOS)
        set_target_properties(BLETester PROPERTIES MACOSX_BUNDLE_INFO_PLIST "${CMAKE_CURRENT_SOURCE_DIR}/Info.plist")
    endif()
endif()

target_link_libraries(BLETester
    PRIVATE
        Qt::Bluetooth
        Qt::Core
        Qt::Gui
        Qt::Qml
        Qt::Quick
        Qt::Positioning
        Qt::Location
        Qt::Widgets
)

install(TARGETS BLETester
    BUNDLE DESTINATION .
    LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR}
    RUNTIME DESTINATION ${CMAKE_INSTALL_BINDIR}
)

    And included in bleinterface.h:

    #include "aes.hpp"

    And used in bleinterface.cpp:

    AES_init(0);
AES_ECB_encrypt(in_Buffer, key, output_Buffer, value[2]);

    Thank you.

    @vcasado said in Undefined symbols for arm64:

    aes.h aes.hpp

    are aes.h and aes.hpp same? It is rare to define two files like that.

      @JoeCFD No, the .hpp is like a wrapper that contains:

      #ifndef _AES_HPP_
#define _AES_HPP_

#ifndef __cplusplus
#error Do not include the hpp header in a c project!
#endif //__cplusplus

extern "C" {
#include "aes.h"
}

#endif //_AES_HPP_

      But in the CMakeLists.txt, the .h is included so it does not report that file not found when compiling

        I know nothing about this, but are you sure the 2 undefined references with those parameters are really supposed to be in Tiny AES's library aes.h? When I look at e.g. https://morioh.com/p/67a35723557d or https://github.com/kokke/tiny-AES-c/blob/master/aes.h I do not see either of them?

          @JonB You are right, now the usage in bleinterface.cpp is:

              struct AES_ctx ctx;
    AES_init_ctx(&ctx, key);

    for (int i = 0; i < 4; ++i)
    {
        AES_ECB_encrypt(&ctx, in_Buffer + (i * 16));
    }

          And the error is:

          Undefined symbols for architecture arm64:
  "_AES_ECB_encrypt", referenced from:
      BLEInterface::onCharacteristicChanged(QLowEnergyCharacteristic const&, QByteArray const&) in bleinterface.o
  "_AES_init_ctx", referenced from:

            I also know nothing about cmake :) Can you at least show the full linker command line it uses, let's see whether libaes.a is even there? Assuming it comes with a library not just source code you compile into yours. I also know nothing about Android/iOS building!

              @JonB There is no compiled library, that is why I am compiling it as it would be more sources of my project

                You have locked your project to C++ only. Remove that and rebuild.

                    I'm purely guessing, but chage this? E.g. ... LANGUAGES CXX C?
