我是谷歌测试框架的新手，并试图探索它。我尝试了一些简单的例子，一切都奏效了。
但是当我用 gtest 测试我的 OpneCV 程序（opencv 目前没有使用任何功能，只添加了头文件）时，它给了我段错误。举个例子
#include<iostream>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
//for gtest API
#include "gtest/gtest.h" ///for google test framework
int main( int argc, char** argv )
{
testing::InitGoogleTest(&argc, argv);
return RUN_ALL_TESTS();
}
TEST(Test, EqualityCheck) {
ASSERT_EQ(1,1)<<"Test Passed";
}
如果在没有 openCV 链接的情况下编译它，那么一切正常
g++ -o out cv_gtest.cpp -I/usr/local/include -I./inc /usr/local/lib/libgtest.a
但是如果使用 opencv 链接编译，我们会在运行时出现 seg 错误
g++ -o out cv_gtest.cpp -I/usr/local/include -I./inc /usr/local/lib/libgtest.a `pkg-config opencv --cflags --libs`
输出：
