[Help, please] Problems building source code on Windows

[phamhoanganhbk]

Hi everyone, I tried to build source code on Windows. (specifically the code sample slam_icp_simple_example). Step 1: Download source code git clone https://github.com/MRPT/mrpt.git --recursive Step 2: Use CMake GUI to generate project files for VS2022 But it always has GLFW library path problem even though I tried many ways to install it.

Selecting Windows SDK version 10.0.19041.0 to target Windows 10.0.22000. CMake Error at C:/Program Files/CMake/share/cmake-3.25/Modules/CMakeFindDependencyMacro.cmake:47 (find_package): By not providing "Findglfw.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "glfw", but CMake did not find one. Could not find a package configuration file provided by "glfw" with any of the following names: glfwConfig.cmake glfw-config.cmake Add the installation prefix of "glfw" to CMAKE_PREFIX_PATH or set "glfw_DIR" to a directory containing one of the above files. If "glfw" provides a separate development package or SDK, be sure it has been installed. Call Stack (most recent call first): C:/Program Files/mrpt-2.5.6/lib/cmake/mrpt-nanogui/mrpt-nanogui-config.cmake:43 (find_dependency) C:/Program Files/CMake/share/cmake-3.25/Modules/CMakeFindDependencyMacro.cmake:47 (find_package) C:/Program Files/mrpt-2.5.6/lib/cmake/mrpt-gui/mrpt-gui-config.cmake:43 (find_dependency) CMakeLists.txt:26 (find_package) Configuring incomplete, errors occurred! See also "D:/github/mrpt/samples/slam_icp_simple_example/build/CMakeFiles/CMakeOutput.log".

Could you give me some advice, please ? (I have successfully tested it on Ubuntu) Many thanks,

Hi,

If you git cloned the sources, why is cmake detecting what seems to be an already built version under C:/Program Files/mrpt-2.5.6/... ??

If you formerly installed mrpt in Windows with the installer, please uninstall it first (through the usual "Control Panel -> Apps" ), remove the cmake build directory, open cmake-gui again, select as source dir the place where you cloned the repo, and as build directory a new, empty directory somewhere else, and try again...

It's supposed to build ok, including nanogui, under Windows on our CI pipeline so it should work... let me know if you still have problems after following those steps.

Hi @jlblancoc Thank you for your reply. I uninstalled the mrpt installer and then i removed the cmake build directory of slam_icp_simple_example (because i just want to run the sample, i don't know if i need to build the mrpt project first?). Then it came up with another error

Hi, I have solved the problem. For those new (like me) on Windows who want to test the samples Step 1: Download source code (not Installer) Step 2: CMake GUI, follow the author's instructions. But pay attention to click on MRPT_BUILD_EXAMPLES (I forgot in this step). Step 3: Link *.dll libraries to sample projects.
