The latest version of Edouard Alligands talk on Multiplatform development with C++:

Multiplattform C++

by Edouard Alligand

From the talk description:

C++ is a multiplatform language, yet many difficulties arise when you want the same code to compile properly and function identically on different platforms. If you put aside the obvious system programming related obstacles, and the differences you might have between compilers (especially when it comes to supporting C++11 and C++14), you come to the surprising conclusion that what is truly hard is all the “little things” you didn’t anticipate.
