To print the result of a shell script in CMake, you can use the execute_process command provided by CMake. This command allows you to execute a shell command and capture its output. You can then use the OUTPUT_VARIABLE option to store the output in a variable, which can be printed later on in your CMake script.
Here is an example of how you can print the result of a shell script in CMake:
1 2 3 4 5 6 7 |
execute_process( COMMAND sh -c "echo Hello, World!" OUTPUT_VARIABLE output OUTPUT_STRIP_TRAILING_WHITESPACE ) message("The result of the shell script is: ${output}") |
In this example, the shell script echo Hello, World! is executed using the sh -c command. The output of the script is stored in the variable output, which is then printed using the message command.
By following this approach, you can easily print the result of a shell script within your CMake scripts.

What is the best way to print the result of a shell script in CMake?
One way to print the result of a shell script in CMake is to use the execute_process command. Here is an example of how you can run a shell script and print its output in CMake:
1 2 3 4 5 6 7 8 9 10 |
execute_process(COMMAND sh -c "your_shell_script.sh" OUTPUT_VARIABLE SCRIPT_OUTPUT RESULT_VARIABLE SCRIPT_RESULT ERROR_VARIABLE SCRIPT_ERROR) if(SCRIPT_RESULT EQUAL 0) message(STATUS "Shell script output: ${SCRIPT_OUTPUT}") else() message(STATUS "Error running shell script: ${SCRIPT_ERROR}") endif() |
In this example, the execute_process command is used to run the shell script and capture its output, result, and any errors. The ${SCRIPT_OUTPUT} variable holds the output of the script, which can then be printed using the message command. The ${SCRIPT_RESULT} variable holds the return code of the script, which can be used to check if the script ran successfully. If the return code is not 0, an error message is printed instead.
What is the procedure for displaying the output of a shell script in CMake?
To display the output of a shell script in CMake, you can use the execute_process command. Here is a simple example of how you can do this:
1 2 3 4 5 6 7 8 9 10 11 |
# Define the shell script command set(SHELL_SCRIPT_COMMAND "sh" "-c" "echo 'Hello, World'") # Execute the shell script command and capture the output execute_process( COMMAND ${SHELL_SCRIPT_COMMAND} OUTPUT_VARIABLE SHELL_SCRIPT_OUTPUT ) # Display the output message("Output of shell script: ${SHELL_SCRIPT_OUTPUT}") |
In this code snippet, we first define the shell script command that we want to execute as a list of strings. We then use the execute_process command to execute the shell script command and capture the output in the SHELL_SCRIPT_OUTPUT variable. Finally, we use the message command to display the output of the shell script.
You can customize this example to execute any shell script command and display its output in CMake.
What is the proper method for outputting the result of a shell script in CMake?
One way to output the result of a shell script in CMake is to use the execute_process command. This command allows you to run a shell command and capture its output.
Here is an example of how you can use execute_process to run a shell script and output its result in CMake:
1 2 3 4 5 6 7 8 9 10 |
execute_process(COMMAND sh myscript.sh OUTPUT_VARIABLE SCRIPT_OUTPUT RESULT_VARIABLE SCRIPT_RESULT ) if(SCRIPT_RESULT EQUAL 0) message(STATUS "Script output: ${SCRIPT_OUTPUT}") else() message(WARNING "Script failed with result ${SCRIPT_RESULT}") endif() |
In this example, execute_process runs the shell script myscript.sh and captures its output in the variable SCRIPT_OUTPUT. It also captures the result of the script execution in the variable SCRIPT_RESULT. If the script executes successfully (i.e. SCRIPT_RESULT is 0), the result is output using message(STATUS). Otherwise, a warning message is output.
This method allows you to run shell scripts and capture their output within your CMake scripts.
How to handle the output of a shell script in CMake?
To handle the output of a shell script in CMake, you can use the execute_process command. Here is an example of how you can use this command to run a shell script and capture its output:
1 2 3 4 5 6 7 8 9 |
execute_process(COMMAND /path/to/your/script.sh OUTPUT_VARIABLE SCRIPT_OUTPUT RESULT_VARIABLE SCRIPT_RESULT) if(SCRIPT_RESULT EQUAL 0) message("Shell script executed successfully. Output: ${SCRIPT_OUTPUT}") else() message("Shell script failed to execute. Return code: ${SCRIPT_RESULT}") endif() |
In this example, the execute_process command is used to run the shell script script.sh and capture its output in the variable SCRIPT_OUTPUT. The return code of the script is stored in the variable SCRIPT_RESULT. You can then use an if statement to check if the script executed successfully or not, and print the output or return code accordingly.
What is the simplest way to capture and print the output of a shell script in CMake?
One simple way to capture and print the output of a shell script in CMake is to use the execute_process command. Here's an example that demonstrates how to achieve this:
1 2 |
execute_process(COMMAND bash -c "ls -l" OUTPUT_VARIABLE output) message("The output of ls -l is: ${output}") |
In this example, the execute_process command is used to run the shell script ls -l, which lists the files in the current directory. The OUTPUT_VARIABLE option is used to capture the output of the shell script in the variable output. Finally, the message command is used to print the output to the console.
