I want to set up an environment on my PC (Win7x64) that I will be able to combine these projects and compile them into one executable:
FFmpeg
AMV codec tools
For this I need an environment that can compile/debug both the above projects (creating a Windows compatible exe).
Any ideas?

eclipse is recommended with official wiki

Please note: Although I'm specifically talking about the Eclipse CDT plugin, I'm almost 100% confident that any Windows/C/MinGW programmer can answer this question.
I'm on Windows 7 and am trying to write and compile a simple "Hello, C!" C application using Eclipse's CDT plugin. I'm reading their docs which state that having GCC installed is a prerequisite.
I just installed MinGW, making sure to include the following packages:
mingw-developer-toolkit
mingw32-base
mingw32-gcc-g++
msys-base
Back in the CDT docs (under the section titled Windows configuration), it states that I need to add g++, make and GDB to my PATH.
I'm wondering where MinGW installs these utilities, so that I can add them to my system PATH, and make the Eclipse CDT recognize their location at startup.
When using the Eclipse CDT plugin, you need GCC and its 3 specific utilities installed locally. These three utilities are: g++, make and gdb.
On Windows you can choose to install these utilities via Cygwin or MinGW. For a MinGW-based solution, go to their site and download the MinGW Package Manager. Then open the manager and install the following packages:
mingw-developer-toolkit
mingw32-base
mingw32-gcc-g++
msys-base
Then go to File >> Apply Updates and apply them. This will install the 3 utilities to the following directories on your machine:
C:\MinGW\bin\g++
C:\MinGW\bin\gdb
C:\MinGW\msys\1.0\make
Add these 3 binaries to your system PATH, restart Eclipse and you are all set.
I am newbie in cygwin. However, I have used mingw so far, but it is not supporting fork(), so I need to switch to cygwin.
Does cygwin support opencv and how (reference)?
I'm the maintainer of http://hvrl.ics.keio.ac.jp/kimura/opencv/. I fixed the bug in loading jpeg files. Please check my new patch.
I just installed opencv with cygwin, all recent distributions. I found ** THIS LINK ** very helpful. You're suppose to install first ffmpeg, then to patch opencv 2.4.2 distribution (!!) and, eventually, to install opencv.
To make it work with pkg-config I had to modify ${OPENCV_ROOTDIR}\lib\pkgconfig and to filter windows path syntax to unix path syntax. pkg-config is not mandatory but it simplifies application development (when correctly installed).
After some effort all this works; but if I can open pgn image files I can't open jpeg image files... Still investigating...

This is what i currently have installed on my home computer:
http://www.eclipse.org/downloads/packages/eclipse-ide-cc-developers-includes-incubating-components/indigosr2
Now, that was a pain to setup because you needed to use Cygwin to install a bunch of stuff in order for Eclipse to compile and run a C project. I found this the other day:
http://www.eclipse.org/cdt/
Does Eclipse CDT come with everything it needs to compile and run a C program or does it still depend on external files? Does it come with a standard library?
You do not have to use Cygwin and you can use alternatives such as mingw (it is simpler for most people to install). Checkout this tutorial for detailed description how to setup on Windows:
http://www.banym.de/eclipse/install-eclipse-cdt-on-windows-7
Compiler is responsible for standard library and in the case mentioned above it is mingw.

I have install the C/C++ CDT Version of Eclipse.
After making a HelloWorld.c file and get the code in there I get an error of "Launch failed. Binary not found".
I found in google that my Eclipse miss the compiler and I install MinGW on my computer and add the path to env variables (tested it with "gcc -v" in cmd and succeded).
But poorly it get the same Launch Failed error - any ideas, what step I forgot?
Some things to check:
1.) MinGW tools are installed as well. Make sure you have the C compiler and the Make program
2.) Check your Environment variables. Make sure both the compiler and Make are on the path.
3.) Eclipse is a temperamental beast at times, don't lose heart :-)
4.) If you're looking for a good IDE (without care for ideological concerns), might be worth looking at Bloodshed C++ IDE and Visual C++ 2010 express (or whatever they call their free version).
5.) Check the options menu in Eclipse to make sure it's looking at the correct environment variables for finding the Path.
IMHO, the simplest setup for eclipse on windows these days is cygwin - it seems to have been updated more recently than mingw, and works better.
Go to http://www.cygwin.com/, download the installer, select the default directory of c:\cygwin. Select 'All users'.
When it offers a list of packages, select 'gcc', 'binutils' and 'make' under the 'devel' category.
Add c:\cygwin\bin to your windows environment PATH.
Make sure Eclipse knows where to find your gcc compiler. An easier way would be to use EasyEclipse until you are more comfortable with your dev env.
I needed to move from the MinGW gcc to the CygWin gcc - all the C++2011 works and others say it is a better option too. Download the CygWin binaries etc. and then open up Eclipse.
In project properties, C/C++ Build -> Environment and set the CYGWIN_HOME variable. This worked fine for me on Eclipse Kepler Windows 7 (64Bit)
I also put the cygwin bin directory at the front of my Windows PATH variable.

You can try installing wascana. It automatically set up GNU compiler for you on Windows.
The question is in the title. Using GCC version 3.4.5 on Windows Vista and a recent version of the Eclipse C/C++ IDE (not sure what version exactly because it's hard to figure out which version is the one for the whole IDE, but I downloaded it two weeks ago so it can't be that old).
This depends on the build system you use, but you can always try adding the "CFLAGS=-std=c99" as a build and/or environment variable the the builder.
