Hey, guys!
I've just posted a video in which I show an easy way to include Assembly into C++. What do you think about it? I think it might help novice people get into Assembly.

Converting assembly language into its C/gcc/asm("") directive style include is interesting for sure, though I am not sure I would classify it as easy. Lots of possibilities to screw up this fragile process.

Admittedly Windows is not my thing anymore, but can't fasm produce a Windows object file that could be ABI compliant and linkable to an otherwise normal C/C++ project like I do for Linux?

If I followed that correctly, your method includes asm as inline asm() blocks in C++ projects? That's more flexible than linking against MS COFF functions in ways since you have to deal with the calling conventions. On the other hand, you have to have some C++ where you can plop the inlined asm.

Vid has an example using the MS COFF function linking method:

which is similar to the Linux HeavyThing method. Using the function linking method, you can call functions and access variables even from other asm, without C++. I've found it very useful, but inlining asm using automation is worth exploring too.
