C++ 20 (2a) New Features - How to Build Examples

The video tutorial guides viewers through building examples using CMake, focusing on different sections that require specific GCC versions. It starts with building Section 2 using GCC 9 and then transitions to Section 4, which requires GCC 10. The tutorial covers downloading prerequisites, configuring, and compiling with GCC 10. It emphasizes the importance of compiling each section separately due to different compiler requirements. The video concludes with a brief introduction to the next topic on string formatting using the new CD format.

What is the primary reason for building sections one by one in the tutorial?

• To save time during the build process

• To ensure each section uses the correct compiler version

• To reduce the size of the build directory

• To avoid downloading unnecessary libraries

Why is GCC 10 specifically required for Section 4?

• It has better library support

• It is the default compiler for all sections

• It is faster than GCC 9

• It supports the new comparison operator

What is the purpose of disabling Multilib during the GCC compilation?

• To enable support for multiple architectures

• To make the compilation process faster

• To reduce the number of required libraries

• To ensure compatibility with older systems

Where will the newly compiled GCC be installed?

• In the temporary build directory

• In the directory specified during the configure step

• In the system's default directory

• In the home directory

What is the size of the resulting build directory after compilation?

• 7.8 gigabytes

• 9.4 gigabytes

• 5.2 gigabytes

• 12.1 gigabytes

What should be done after compiling each section to ensure proper functionality?

• Compile each section separately

• Compile all sections together

• Reinstall all libraries

• Use the same compiler for all sections

What is the next topic to be covered after the compilation process?

• Debugging compiled code

• Advanced CMake techniques

• String formatting using new CD format

• Optimizing build performance
