Contents
All of the source Markdown pages for the Modern C++ Tutorial on https://learnmoderncpp.com/ plus complete, working programs from the course text.
The "headers" subdirectory contains C++ programs with legacy header #includes, whilst the "modules" subdirectory contains the same programs using the import keyword instead. See https://learnmoderncpp.com/2020/09/05/where-are-c-modules/ for more details about C++ compilers which have support for modules.
The "scripts" subdirectory contains a C++ program which extracts all programs from the Markdown source to the above two folders.
Compiling under Windows
Most programs compile successfully under Windows with Visual Studio 2022 (v17.5 or later), some of the modules versions do not currently compile.
The supplied batch scripts build-vs2022-headers.bat and build-vs2022-modules.bat can be used to compile all of the programs within a Visual Studio command prompt, simply run:
C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvars64.bat
or similar in a command window, or create a desktop link, and then run either of the build scripts.
Alternatively, to compile individual programs from within a Visual Studio command prompt run either (modules):
cl /EHsc /std:c++latest /MTd 00-example.cpp
or (headers):
cl /EHsc /std:c++latest 00-example.cpp
substituting the correct file for 00-example.cpp in either case. Note that the modules versions need file std.obj in the current directory, see the build script for how to create this.
Compiling under Linux
To compile individual programs in the "headers" subdirectory under Linux, use:
g++ -std=c++20 -o 00-example 00-example.cpp
or:
clang++ -std=c++20 -o 00-example 00-example.cpp
substituting both occurrencies of 00-example with the correct file name.
Alternatively, run one of the supplied shell scripts build-gcc-headers.sh or build-clang-headers.sh which are supplied in the "headers/build" subdirectory, or build-clang-modules.sh found in the "modules/build" subdirectory.
