To print the working directory in CMake, you can use the following command:
1
|
message(STATUS "Current working directory: ${CMAKE_CURRENT_SOURCE_DIR}")
|
This will display the current working directory in the CMake output when the project is being configured or built.

How to troubleshoot issues related to locating and printing the working directory in CMake?
- Check the CMakeLists.txt file: Look for any commands or functions related to setting the working directory or printing it. Make sure the syntax is correct and there are no typos.
- Use message() command: Add a message() command in the CMakeLists.txt file to print out the current working directory. This can help identify any issues with the working directory.
- Use get_filename_component() function: Use the get_filename_component() function to get the absolute path of the current working directory. Make sure to store the result in a variable and print it to verify if it is correctly obtained.
- Check CMake cache variables: Check if any cache variables are affecting the working directory setting. These variables can override default settings and cause issues with locating and printing the working directory.
- Verify the build directory: Make sure you are running CMake in the correct build directory where the executable is generated. If you are running CMake in a different directory, it may not be able to locate the working directory correctly.
- Use message() command with variables: Use the message() command with variables to print out the values of any variables related to the working directory. This can help identify if the variables are set correctly.
- Check the output of CMake: Look at the output of the CMake command to see if there are any errors or warnings related to locating or printing the working directory. Address any issues that are raised in the output.
- Consult the CMake documentation: If you are still unable to troubleshoot the issue, consult the CMake documentation or seek help from the CMake community forums. There may be specific guidelines or tips for handling working directory related issues in CMake.
What is the best practice for printing the working directory in CMake?
The best practice for printing the working directory in CMake is to use the message() command to display the current working directory. Here is an example of how you can print the working directory in CMake:
1
|
message("Current working directory: ${CMAKE_CURRENT_SOURCE_DIR}")
|
This will display the current working directory in the CMake output when the CMake script is run. This can be useful for debugging and confirming that the correct working directory is being used in your CMake project.
What is the difference between the working directory and the source directory in CMake?
In CMake, the working directory is the directory from which the CMake command is executed. This is where the build system will create the build files and generate the build artifacts.
The source directory, on the other hand, is the directory containing the CMakeLists.txt file and the source code of the project. This is where all the source files that need to be built are located.
In summary, the working directory is where the build happens, while the source directory is where the source code is located.
