Using cygwin and mingw together - windows

I want to use mingw compiler and some mingw stuff from mingw-get
I want to use bash and unix tools that shipped with cygwin. Because MSYS has some deficiencies.
I also want to be able to "switch" from using cygwin-gcc to mingw one and back with same bash session if possible.
I have C:\cygwin and C:\mingw installed and working

The MinGW compiler is available as a Cygwin package. The MinGW-w64 compilers are also available as Cygwin packages. In this way you can use Cygwin for the Linux environment, but also compile executables that do not rely on the Cygwin dll.
I recommend uninstall MinGW completely, and start using Cygwin in this way.

C:\cygwin64\bin does not have gcc.exe, g++.exe

I am using Mingw with code:blocks for years but now I need to to use cygwin64 with code blocks.
So I installed cygwin64 (for 64-bit windows) and the folder C:\cygwin64\bin does not have gcc.exe or g++.exe, while I installed them along with other packages indicated here (NOTE: I do not know if the command prompt runs the gcc/g++ from mingw or from cygwin?)
I do not know if the gcc.exe or g++.exe did not get installed because i also have mingw.
There are many youtube tutorials for this, but they all download the 32-bit version of cygwin. I would like to use the 64-bit. Has anyone done this?
Note that i followed the code:blocks wiki on how to install cygwin, but it does not say whether I need to install the 32 or 64-bit, and there are many points where it says " add [Cygwin]\usr\X11R6\bin (if required)" and ""-3" may need to be changed to "-4"". Unclear documentation!
the gcc compiler is included in the gcc-core package
$ cygcheck -p bin/gcc
Found 10 matches for bin/gcc
gcc-core-10.2.0-1 - gcc-core: GNU Compiler Collection (C, OpenMP)
...
This is valid for both 32bit and 64bit versions of Cygwin.
Fixed it by uninstalling the cygwin64 altogether, and I installed the cygwin 32-bit version. Tutorials on how to install 32-bit version can be found here and here This also installed gcc.exe, g++.exe files in the C:\cygwin\bin folder.

Cross Debug Win32 Mingw32 C/C++ program on Linux and Wine using GDB

I installed mingw-w64 and gdb-mingw-w64 on Ubuntu 14.10 using:
sudo apt-get install mingw-w64
sudo apt-get install gdb-mingw-w64
I'm able to compile C/C++ programs and run them from Wine or on Windows machine.
I installed mingw32 version of gdb to be able to debug windows app compiled with Mingw.
I tried to use recent versions of Netbeans 8, Code::Blocks 13.12, Eclipse Luna and was able to configure Mingw toolchain to be used with IDE for building win32 application from Linux.
I also tried to configure the same way in those IDEs to use Mingw version of GDB (gdb-mingw-w64) the same way as standrad GDB was sued for non-mingw GCC toolchain but was never able to make it work :(
How can I debug such C/C++ program compiled with Mingw from Linux?
How to configure in any of IDEs listed above?
Thank you!

Installing OpenAL (or a similar package) on W7

I want to install OpenAL Haskell bindings for Windows. When I try cabal install alut I get:
Resolving dependencies...
Configuring OpenAL-1.4.0.2...
cabal: The package has a './configure' script. This requires a Unix
compatibility toolchain such as MinGW+MSYS or Cygwin.
Installing MSYS or Cygwin is absolutely not an option. runghc setup configure on the source yields the same thing. This leads me to the following:
How can I install OpenAL with just an installation of the Haskell Platform? I know mingw comes with the Haskell Platform on Windows. Can I use just that to execute this script?
Is there a package that can play audio that installs with cabal on Windows 7 AND Unix based systems?
The source contains hundreds of directives designed for the configure script, which doesn't work on Windows. Is there a version of the source which is platform specific, ie, the script has already been run in a windows environment?
Edit: Context for the problem:
I have a Haskell program, which among other things, plays sound. It is going to be used for demonstration/interactive presentation to students. The computers in the lab run Windows 7. They have the Haskell Platform installed, but not MSYS or Cygwin. I have about 45 minutes to complete this, which doesn't leave time for the installation of needlessly complex and essentially pointless software. If I could get Windows-compatible source code, I could just distribute it with the program I wrote. All the packages I need besides this one will cabal install just fine; this is also a good introduction to package management.
Edit2: cabal install fails with Cygwin installed, as does runghc setup configure

How to build GCC 4.7 on Windows?

How to build GCC 4.7 on Windows?
You are not finding instructions on how to do this because you cannot natively use gcc in Windows. Your options are either to use gcc through Cygwin [installation instructions] or install the MinGW port [installation instructions].
You can also find links to these projects on the Installing GCC: Binaries page.
Well, gcc 4.7 has not yet been released (it will be released in a few months, i.e. spring 2012).
If your system is Windows then I am sorry for you, Linux is so much better :-) More seriously, you should search for cygwin gcc. I cannot help you in that case.
What did you try? Building GCC (even on Linux) is not an easy task. Some hints (which I guess are also relevant to cygwin & windows).
Always configure and build the compiler in a build tree outside of the source tree. (this is a common mistake).
take care of the many dependencies (and their versions), like the Parma Polyhedra Library, Cloog, etc ...
some features of GCC are not available on Windows. In particular plugins.
I would suppose that installing the binary of an older variant of cygwin gcc (and all the related packages) will help.
But really, I know nothing about Windows. And if you really want a very recent GCC and you cannot install Linux (or build GCC cygwin), you might perhaps consider running Linux in an emulator or virtual machine.

How to compile a Windows binary in Ubuntu?

I have a Qt application that I can compile in Ubuntu 10.04 64-bit and on Windows. However, I would like to avoid switching to Windows every time I want to compile the Windows version.
Is there a way I can compile a Windows Qt executable in Ubuntu with mingw32 or something?
Further, is there a way to integrate that compiler into Qt Creator?
There is a PPA (Personal Package Archive) for some people who are cross-compiling Qt and related software on Ubuntu for Windows. The PPA contains both the cross-compilers and the dependencies you will need to cross-compile Qt programs. If you look at the source packages there, I think you will be able to figure out how to configure your projects and build them.
If you most of your time spend coding with Qt on Linux (for example, Ubuntu), you may produce some experiment: install Wine, install Qt SDK for Windows with Wine and tried to build some simple project!
And if you don't like crazy things, which I wrote above, just use VirtualBox.
