Hi,

I am trying to create some sample unit tests for the package library I am creating. It looks like the library is being created but I get an undefined reference error. it looks like the test code couldn't link to the library.

I have a near empty class that has a function that returns a string and a test that checks the value of the returned string. The cmakelist file and package file are shown below:

thanks. i will use that when i link packages.

My bad. I actually had a mistake in the code. Forgot to put namespace in the cpp file. Sorry about that. The linking see

[ROS2] correct way to link to created library in gtest Hi, I am trying to create some sample unit tests for the package

I am trying to create a new package and some unit tests for that package. In the cmake option, I put the find_package(ament_gtest REQUIRED) line to make sure that the system can use gtest. However, it looks like cmake can't find the ament_gtest package and I am getting the following error

--- stderr: configurator
CMake Error at CMakeLists.txt:43 (find_package):
  By not providing "Findament_gtest.cmake" in CMAKE_MODULE_PATH this project
  has asked CMake to find a package configuration file provided by
  "ament_gtest", but CMake did not find one.

  Could not find a package configuration file provided by "ament_gtest" with
  any of the following names:

    ament_gtestConfig.cmake
    ament_gtest-config.cmake

  Add the installation prefix of "ament_gtest" to CMAKE_PREFIX_PATH or set
  "ament_gtest_DIR" to a directory containing one of the above files.  If
  "ament_gtest" provides a separate development package or SDK, be sure it
  has been installed.

sorry I was a bit slow to pick up what your original answer meant. It now works if I change the name in the CMakeList.
