To get a verbose output for CMake, you can use the "-DCMAKE_VERBOSE_MAKEFILE=ON" flag when generating the build system with CMake. This flag will cause CMake to generate makefiles that provide more detailed output during the build process, including the exact commands being executed and their output. This can be useful for troubleshooting build issues and understanding the build process better.

How to get a verbose output for cmake on Linux?
To get a verbose output for cmake on Linux, you can use the following command:
1
|
cmake --debug-output <path/to/source>
|
This command will provide detailed information on the cmake configuration and build process, including verbose output for each step. You can also use the -H flag to specify the path to the CMake project directory and the -B flag to specify the path to the build directory.
Additionally, you can set the CMAKE_VERBOSE_MAKEFILE variable to ON in your CMakeLists.txt file to get verbose output during the build process:
1
|
set(CMAKE_VERBOSE_MAKEFILE ON)
|
This will display all commands that are executed during the build process.
What is the syntax for enabling verbose output in cmake?
To enable verbose output in CMake, you can use the "-DCMAKE_VERBOSE_MAKEFILE=ON" option when generating the build system. This can be done by running cmake with this additional flag like:
1
|
cmake -DCMAKE_VERBOSE_MAKEFILE=ON /path/to/source
|
Alternatively, you can set the environment variable CMAKE_MAKE_PROGRAM to the make program you are using (e.g., "make VERBOSE=1") or run make with the VERBOSE=1 option to enable verbose output.
1
|
make VERBOSE=1
|
These options will display more detailed information about the build process, such as what commands are being executed and the output of those commands.
How to enable verbose logging for cmake configuration process?
To enable verbose logging for the CMake configuration process, you can add the following command line option when running CMake:
1
|
cmake --trace <path_to_CMakeLists.txt>
|
This will enable verbose logging and provide detailed information about the configuration process. Additionally, you can also use the following command line options to further customize the logging level:
1 2 |
cmake --trace-redirect=log.txt <path_to_CMakeLists.txt> cmake --trace-format=summary <path_to_CMakeLists.txt> |
These options will redirect the verbose output to a file called log.txt and format the output in a summarized manner, respectively.
Alternatively, you can also set the CMake variable CMAKE_MESSAGE_LOG_LEVEL to a higher value (e.g. DEBUG) in your CMakeLists.txt file to enable verbose logging for the specific project.
1
|
set(CMAKE_MESSAGE_LOG_LEVEL "DEBUG")
|
This will output detailed information about the configuration process for that specific project.
How to get real-time output while running cmake with verbose mode?
You can get real-time output while running cmake in verbose mode by using the following command in the terminal:
1
|
cmake --verbose=1 path_to_source_directory
|
This command will run cmake in verbose mode and display real-time output as the build progresses. You can adjust the verbosity level by changing the value after the --verbose flag (e.g. --verbose=2 for more detailed output).
