Im trying to create an executable from a console application. I have installed mono,cygwin (mingw-gcc, mingw-zlib1, mingw-zlib-devel, pkg-config) and I have added the following lines to my .bashrc file
export PKG_CONFIG_PATH=/cygdrive/c/progra~1/Mono-3.2.3/lib/pkgconfig
export PATH=$PATH:/cygdrive/c/progra~1/Mono-3.2.3/bin
export CC="i686-pc-mingw32-gcc -U _WIN32"
But everytime I try to use mkbundle I receive the following message
Is there a way to make mkbundle work properly on windows.?
(Im using windows 7 x86, mono 3.2.3, the cygwin I found on the official website, xamarin studio 4.2 and net framwork 4)

1. Create: Used to Create a new empty file. Syntax in C language: int create(char *filename, mode_t mode)
To write a C code file in Notepad, type your C code into a blank page in the text editor, and then save the file with a ". c" file extension if the file consists of a C code page, or the ". h" file extension if the file consists of header code.
The Microsoft C/C++ for Visual Studio Code extension supports IntelliSense, debugging, code formatting, auto-completion. Visual Studio for Mac doesn't support Microsoft C++, but does support .

This problem is still presented in the current mono version under the Windows. This happened because of mono team switched default GC to SGEN. So when you try to use mkbundle as you can see in your error mkbundle utility try to find mono-2 library but this lib didn't included in setup and you have a fail. To solve this you should configure mkbundle to use libmonosgen-2.0 instead of mono-2. Let's try to do this.
The key moment is setting this variable:
export PKG_CONFIG_PATH=/cygdrive/c/progra~1/Mono-3.2.3/lib/pkgconfig
If you go to this directory you will see a lot of *.pc files (package config). This files are responsible for configuration of linking libraries during bundling process. For some reasons mono team hard coded package config file and library to mono-2 (see this line 492). How could we fix it without rebuilding mkbundle? The solution is to use the next bundle script:
# Mono paths
mono_version="3.2.3"
export MONO=/cygdrive/c/progra~2/Mono-$mono_version
machineconfig=$PROGRAMFILES\\Mono-$mono_version\\etc\\mono\\4.5\\machine.config
export PATH=$PATH:$MONO/bin
export PKG_CONFIG_PATH=$MONO/lib/pkgconfig
# Compiller
export CC="i686-pc-mingw32-gcc -U _WIN32"
# Output file name
output_name=Prog.exe
# Produce stub only, do not compile
mkbundle --deps --machine-config "$machineconfig" -c Program.exe
# Produce helper object file. You may see errors at this step but it's a side effect of this method.
mkbundle --deps --machine-config "$machineconfig" -oo temp.o Program.exe
# Compile. Pay attention where I use monosgen-2
i686-pc-mingw32-gcc -U _WIN32 -g -o "$output_name" -Wall temp.c `pkg-config --cflags --libs monosgen-2` temp.o
# Copy libmonosgen-2.dll
cp $MONO/bin/libmonosgen-2.0.dll .
# Run
./$output_name
