无法在 Apple Silicon 上使用 Boost.Test 在 cmake 项目中构建测试套件

Question

我在 Apple Silicon 电脑上关注 JetBrains's tutorial。我用 MacPorts 安装了 boost (sudo port install boost)，版本是 1.71 构建 tests.cpp 文件失败，出现以下错误：

ld: warning: ignoring file /opt/local/lib/libboost_unit_test_framework-mt.dylib, building for macOS-x86_64 but attempting to link with file built for macOS-arm64

我在 tests.cpp 中的代码：

#define BOOST_TEST_MAIN
#define BOOST_TEST_MODULE my_unit_tests
#define BOOST_TEST_DYN_LINK

#include <boost/test/unit_test.hpp>
#include "../calc.h"

BOOST_AUTO_TEST_SUITE(my_testsuite)

    BOOST_AUTO_TEST_CASE(addvalues_zero)
    {
        BOOST_TEST(add(0, 0) == 0);
        BOOST_TEST(add(-5, 5) == 0);
    }

    BOOST_AUTO_TEST_CASE(addvalues_negpos)
    {
        BOOST_TEST(add(-5, 10) == 5);
        BOOST_TEST(add(-10, 5) == -5);
        BOOST_TEST(add(5, 10) == 15);
    }

BOOST_AUTO_TEST_SUITE_END()

我在 test/CMakeLists.txt 中的代码：

set(Boost_USE_STATIC_LIBS OFF)
find_package(Boost REQUIRED COMPONENTS unit_test_framework)

include_directories(${Boost_INCLUDE_DIR})

add_executable(test tests.cpp)
target_link_libraries(test ${Boost_LIBRARIES})
target_link_libraries(test test_lib)

我在 cmake-build-debug 文件夹中有这个库，并且我在主 CMakeLists.txt 中包含了测试子项目。

Answer 1

添加

set(CMAKE_OSX_ARCHITECTURES, arm64)

在根CmakeLists.txt的最开始。

Answer 2

也许你也需要这个：

set(CMAKE_SYSTEM_PROCESSOR arm64)
set(CMAKE_OSX_ARCHITECTURES arm64)

顺便说一句，如果您遇到这些错误，可能是您使用了过时的 macOS 版本，或者您没有下载 XCode。
