Linker unable to find object references when using gtest (C++)
0
I decided to get started with unit tests and wrote my first one using gtest. Here's the source:
DetectorTests.cpp:
#include <gtest/gtest.h>
#include <ros_layer/utils/DetectorUtils.h>
class DetectorTests : public ::testing::Test {
public:
DetectorTests() {
}
bool initTestFixture() {
return true;
}
virtual void SetUp() {
ASSERT_TRUE(initTestFixture());
}
virtual void TearDown() {
}
};
// Test where the robot does a vector operation
TEST_F(DetectorTests, testNoDetect) {
// Parameters get set up here
ros::NodeHandle privateNodeHandle("~");
std::shared_ptr<ros_layer::DetectorUtils> distDetector = std::make_shared<ros_layer:DetectorUtils>(privateNodeHandle);
// @to-do set up object parameters before running test
ASSERT_FALSE(distDetector->checkReadings());
}
int main(int argc, char** argv) {
ros::init(argc, argv, "detection_action_test");
::testing::InitGoogleTest(&argc, argv);
return RUN_ALL_TESTS();
}
My CMakeLists.txt has the following lines:
find_package(GTest REQUIRED)
catkin_add_gtest(detector-test test/DetectorTests.cpp)
target_link_libraries(detector-test ${catkin_LIBRARIES})
When I run CMake with the arguments to run the tests though, I get this error while linking:
In function `construct<ros_layer::DetectorUtils, ros::NodeHandle&>':
/code/include/c++/4.8/ext/new_allocator.h:120: undefined reference to `ros_layer::DetectorUtils::DetectorUtils(ros::NodeHandle&)'
CMakeFiles/detector-test.dir/test/DetectorTest.cpp.o: In function `destroy<ros_layer::DetectorUtils>':
/code/include/c++/4.8/ext/new_allocator.h:124: undefined reference to `ros_layer::DetectorUtils::~DetectorUtils()'
If I remove all the unit test related code and just write c++ with the DetectorUtils object being created, I have no trouble at all. What's causing this error and how do I resolve it?

I'm not familiar with ROS, so just a general advice: check the place in your code whereros_layer::DetectorUtils::DetectorUtils(ros::NodeHandle&)is actually defined, check that it is defined in some object file and check the order of libraries given to the linker.

It's defined. When I create the object using the same line without any gtest stuff in the code, it compiles just fine.

If it is the linking problem, the exact command line for linking (make VERBOSE=1) could be helpful.

Solved it. target_link_libraries in my CMakeLists needed to have the library that DetectorUtils is defined in. Here's the updated line:
target_link_libraries(dragging-test ROSLayerLibrary ${catkin_LIBRARIES})
