代码：

include <gtest/gtest.h>

include <emock/emock.hpp>

class MyUsing { public: int Add(int a, int b) { return a + b; } };

class MyRunner { public: int Run(int a) { MyUsing my; return my.Add(a, a * a); } };

int add_stub(int a, int b) { return a+b; }

class MyRunnerTest : public testing::Test { public: protected: virtual void SetUp(){}; void TearDown() override{}; };

TEST_F(MyRunnerTest, TestRun) { MyRunner my; EMOCK(&MyUsing::Add) .stubs() .will(returnValue(2)); EXPECT_EQ(2, my.Run(1)); }

int main(int argc, char *argv[]) { printf("Running main() from %s\n", FILE); testing::InitGoogleTest(&argc, argv); // ros::init(argc, argv, "gs_map_test");

return RUN_ALL_TESTS(); }

查了一下， u.p = SymbolRetriever::getMethodAddress(u.p, typeid(api), name);\ 这个函数取得的函数地址只有5五位数，非真正有效的内存地址，所以 memcpy直接挂了。

我也遇到同样的问题,根本不能用啊,这个还没有解决吗?
