So I'm having a hard time getting DirectX 11 and MinGW to cooperate. MinGW seems to come with some DX11 headers, but I wasn't able to get anything to compile since it couldn't even seem to find a class definition for ID3D11Device.

With some help online I managed to come up with this:

Using this, I managed to compile a simple 32-bit hello world DirectX 11 program which sets up a device and swap chain and back buffer. However, if I compile it as 64-bits, it crashes when I call:


DXGI_SWAP_CHAIN_DESC scd;
ZeroMemory(&scd, sizeof(DXGI_SWAP_CHAIN_DESC));

scd.BufferCount = 1;
scd.BufferDesc.Format = DXGI_FORMAT_R8G8B8A8_UNORM;
scd.BufferUsage = DXGI_USAGE_RENDER_TARGET_OUTPUT;
scd.OutputWindow = hWnd;
scd.SampleDesc.Count = 4;
scd.Windowed = true;

D3D11CreateDeviceAndSwapChain(NULL,
D3D_DRIVER_TYPE_HARDWARE,
NULL, 0,
NULL, 0,
D3D11_SDK_VERSION,
&scd, &swapchain,
&dev, NULL,
&devcon); //crash


Any ideas on how I can get these two to work together better? I really[/d] don't want to have to deal with VC++.

I don't think that you can leave 11th argument NULL.
Also - have you checked that debug logging with DirectX Control Panel doesn't display some obvious error message?

But you really should try using VC++. It's nice IDE, especially when you need to debug code.

That wasn't the issue.

So, I should drop the compiler I'm used to, the one that is free with outstanding support for C++11 and virtually no bugs, and switch to VC++ Express, a non-optimizing compiler with few C++11 features and several bugs that I've personally encountered? I'm not exactly excited about the thought of that.

Edit: OK, I stand corrected, it's supposedly a "fully optimizing" compiler, but I believe GCC still wins by far when it comes to the performance of the code generated by it's auto vectorization.

smart move.. and very nice results. congrats.

Wow. You are incredibly ignorant and arrogant. Thanks for the help buddy.

If the original poster wants to discuss DX11 + MinGW64, then by all means, let him have his topic. There's plenty of room for DX11 + VS2010 threads as well.

Let's not throw in comments based on FUD. GCC is not virtually bug-free: there are 842 outstanding unfixed bugs in the GCC C++ compiler frontend alone. Visual Studio is not bug-free either.

Believing "GCC wins by far in performance" does not make it a correct statement either. It might. Or it might not. Instead of believing, it is better to profile, but unfortunately, there are not that many great sources available that would accurately profile these compilers. Two sources I found

• http://www.g-truc.net/post-0372.html : VC2010 beats GCC by a large margin.
  
• http://www.willus.com/ccomp_benchmark2.shtml?p1 : GCC beats VC2010 in 6 out of 10 tests.
  

I do not mean to derail, now please let's stick to the original topic.

virtually no bugs

You are being silly:
http://gcc.gnu.org/b...&resolution=---
http://gcc.gnu.org/b...&resolution=---
http://gcc.gnu.org/b...&resolution=---
http://gcc.gnu.org/b...&resolution=---

Every software has a bugs. And GCC is no exception from that. I develop with both - gcc and msvc compilers. And both have bugs. Different ones, of course, but they have bugs. Actually in my experience GCC has far more bugs (and worse ones) than MSVC.

Well, I have yet to encounter any serious bug myself in the latest GCC, and with the rate at which new versions and bug fixes are released, I wouldn't expect it to be much of a problem if I did. Visual Studio? Well, if you find a bug (which I have, several), you can wait a couple years and hope their next product comes with a fix. And that doesn't even address the overwhelming lack of support for C++11.

In any case I shouldn't have to defend my personal preference for what is a great compiler. Visual Studio isn't even available on the other platforms I use, and MinGW makes working in Windows easy and consistent. There is really no reason somebody shouldn't be able to compile D3D11 applications with it.

Hi I have the solution to your problem.

I done the same thing a few months back.
What I had to do was download the official windows dx sdk and put the defines as you have done above.
I then had to get the directx dll files and use this
http://sourceforge.n...w64/wiki/gendef
And then from that I created library files to link with.

Lucky for you ruben seems to have added this to his latest personal build.

http://sourceforge.n...ubenvb/4.7.0-1/
Get the gcc build

Best of luck.. post back if you run into any problems
