Question

我正在用 C++ 开发一个项目并编写单元测试并使用 Google 测试库。我使用的是带有 M1 芯片的 MacBook Pro。我通过自制软件安装了 Google Test。在自制的 GTest 页面上，提到 Gtest 与 Apple Silicon 兼容。

Apple Silicon Big Sur ✅ 我正在使用 CLion。

这是我的 CMakeLists.txt 的样子：

cmake_minimum_required(VERSION 3.19)
project(GTest)

include_directories(/opt/homebrew/Cellar/googletest/1.10.0/include)
link_directories(/opt/homebrew/Cellar/googletest/1.10.0/lib)
set(CMAKE_CXX_STANDARD 14)

add_executable(GTest main.cpp)

target_link_libraries(GTest libgmock_main.a)

我需要 .dylib 才能在 arm64 上工作吗？不久前我试图链接 libpq 静态库，它给了我相同的链接错误。然后我尝试链接 .dylib 而不是 .a 并且它在 arm64 上工作。但是我在 lib 目录中没有看到 GTest 的动态库。

以下是通过 homebrew 安装 GTest 后的所有库：

libgmock_main.a
libgtest_main.a
libgmock.a
libgtest.a

我得到的链接错误是：

make: *** [GTest] Error 2

这是我为测试 Google 测试而编写的简单代码：

#include <iostream>
#include <gtest/gtest.h>
using namespace std;

string getStr(string str)
{
    return "1";
}

TEST(TestGetStr, First)
{
    ASSERT_STREQ("2", getStr("Arun").c_str());
}

int main()
{
    ::testing::InitGoogleTest();
    return RUN_ALL_TESTS();
}

在 M1 芯片上通过 Google 测试库编写单元测试时找不到架构 arm64 的符号
