Question

我在使用Google Test时遇到了麻烦。在Ubuntu 17.04上，我使用命令构建了Google Test：

sudo aptitude install libgtest-dev
cd /usr/src/gtest
sudo cmake -DBUILD_SHARED_LIBS=ON .
sudo make
sudo mv libgtest* /usr/lib

然后我尝试编译非常简单的测试文件：

#include <gtest/gtest.h>
#include <iostream>

int foo()
{
    return 4;
}

TEST(TestFoo, test1)
{
    ASSERT_EQ(foo(), 4);
}

int main(int argc, char *argv[])
{
    ::testing::InitGoogleTest(&argc, argv);
    return RUN_ALL_TESTS();
}

并获得以下错误：

$ g++ -lgtest -o simplesample simplesample.cc
