C++11 Examples

Some examples I've made for myself as a reference, in particular the Makefiles (for Linux/OSX and Windows w/ Cygwin)

$ make    # OSX/Linux

$ make -f Makefile.win32 VSVER=11   # Visual Studio 2012
$ make -f Makefile.win32 VSVER=12   # Visual Studio 2013 (default)
$ make -f Makefile.win32 VSVER=14   # Visual Studio 2015

Install a clang-format git post-commit hook to format your code automatically.

$ make install_hooks

Run the programs:

$ make run

clang++ -std=c++11 -MD -MF atomic/atomic.d -O3 -c atomic/atomic.cpp -o atomic/atomic.o
clang -lstdc++ atomic/atomic.o -o atomic/atomic

clang++ -std=c++11 -MD -MF init-once/init-once.d -O3 -c init-once/init-once.cpp -o init-once/init-once.o
clang -lstdc++ init-once/init-once.o -o init-once/init-once

rm -f atomic/atomic init-once/init-once atomic/atomic.o init-once/init-once.o atomic/atomic.d init-once/init-once.d

atomic

Example of C++11 atomic operations.

init-once

Example of C++11 thread-safe static single initialization. Also contains Makefile and scripts to compile with VS11/12/14 from within Cygwin.

filesystem

Example of C++ standard filesystem operations. Finds files older than 48h in your C:\Windows\System32 directory. This also servers as a demo of yield/await added to VS2015SP1.

# from cygwin
$ make filesystem/get_older_files.exe
