Compile under gcc about commandcam

[tedburke]

Hi sgame,

I tried pretty hard to compile some really simple DirectShow video capture programs under MinGW, but I completely failed to get it working. It was like banging my head against a wall and I just ran out of steam and gave up. To be honest, it's messy enough compiling DirectShow programs using cl.exe (the compiler behind Visual Studio). I have no idea why this stuff is so complicated. The Video For Windows API was far from perfect, but at least it was fairly easy to get up and running with it. DirectShow is just horrible. If all programming was like this, I would never have got into it at all.

Anyway, if anyone can get CommandCam to compile under MinGW, I'll be interested to see how they did it.

CommandCAM with MINGW
I used DirectX90c.DevPak and Libs uuid/strmiids/oleaut32/ole32 with included MINGW on Codeblocks 13.12.

Thank you dude, does this hack really work with mingw compilation, can you share the file..
