c++ - 未找到 Gtest 入口点

问题描述

我正在尝试使用 gtest 来测试共享库。我使用 CMake 并且每次构建和编译都没有任何错误，但是 hello_test.exe 退出并出现错误：

未找到入口点。在动态链接库中找不到过程入口点 _ZNKSt7__cxx112basic_stringlcSt11char_traitslcESalcEE4findEPKcyy。

我在通过 rdp 连接的 Windows Server 2016 Standard 上（看起来像 windows10）

我使用 MinGW 8.1.0 (x86_64/win32/seh) 作为编译器。

CMake 3.17.3

我试图在另一台计算机上复制这个环境并且一切正常，所以我需要一些帮助来找到这个环境中缺少的东西，以便我可以修复它。

我看过这个问题

在动态链接库中找不到过程入口点_ZNSt7__cxx1112basic_stringIcSt11char_traitsIcESaIcEEC1Ev

但我查了一下，我的 cxx 编译器是 g++
找不到过程入口点 __gxx_personality_v0

这个答案有效，但为什么 cmake 没有正确链接呢？

这是 MWE。cmake 文件夹包含 https://github.com/robotology/idyntree/tree/master/cmake中的两个实用程序
