Building from source basics in Linux CLI - Practice Problems & Coding Challenges

Challenge - 5 Problems

💻 Command Output

What is the output of the configure script?

You run ./configure in a source directory. What output indicates the script completed successfully?

Linux CLI

./configure

A Configuration complete. Now run 'make' to build.

B Error: missing dependencies. Cannot continue.

C Segmentation fault (core dumped)

D bash: ./configure: No such file or directory

💡 Hint

Look for a message that tells you the next step after configuration.

The configure script checks your system and prepares the build. A successful run ends with a message telling you to run 'make'. Errors or missing files show different messages.

💻 Command Output

What does 'make install' do?

After building software with make, you run make install. What is the expected output?

Linux CLI

make install

A Cleaning up temporary build files

B Compiling source code into object files

C Downloading dependencies from the internet

D Copying files to system directories like /usr/local/bin

💡 Hint

Think about what 'install' means in this context.

'make install' copies the built program files to system folders so you can run them easily. It does not compile or download anything.

📝 Syntax

Which command correctly cleans build files?

You want to remove all files created during the build process using make. Which command is correct?

A make remove

B make delete

C make clean

D make uninstall

💡 Hint

The standard target to clean build files is named after a common English word for tidying.

'make clean' is the standard command to delete temporary build files. 'make uninstall' removes installed files, not build files.

🔧 Debug

Why does './configure' fail with 'No such file or directory'?

You run ./configure but get the error: bash: ./configure: No such file or directory. What is the most likely reason?

Linux CLI

./configure

A You do not have permission to run the script

B The configure script is missing from the source directory

C The script has a syntax error

D Your shell does not support ./ commands

💡 Hint

Check if the file exists in the folder.

This error means the file named 'configure' is not found in the current directory. It might be missing or you are in the wrong folder.

🚀 Application

Order the steps to build software from source

Put these commands in the correct order to build and install software from source.

A 1,2,3,4

B 2,1,3,4

C 1,3,2,4

D 4,1,2,3

💡 Hint

Think about preparing, building, installing, then cleaning.

First, configure prepares the build. Then make compiles. Next, make install copies files. Finally, make clean removes build files.
