R12 (12.1.1) On Windows - Install Cygwin


Cygwin (pronounced  SIG-win) is a Unix-like environment and command-line interface for Microsoft Windows.
Cygwin provides native integration of Windows-based applications, data, and other system resources with applications, software tools, and data of the Unix-like environment. Thus it is possible to launch Windows applications from the Cygwin environment, as well as to use Cygwin tools and applications within the Windows operating context.
Cygwin is free software and is not supported unless you purchase a support contract from a third party providing Cygwin support.
Cygwin is required for the installation and maintenance of the Oracle E-Business Suite (EBS). You can use the MKS toolkit also for maintaining EBS.

Perform the following steps to download and install the Cygwin software.
1- Log in as the Admin User  
Log in as a local administrative user (the user who runs the Rapid Install.). 
2- Create a Cygwin directory
Create the directory where you plan to install Cygwin (called the Root Directory). This directory cannot be under Program Files, or any other directory with blank spaces in its name. In addition, it cannot be under the APPL_TOP.
3- Download the Cygwin Software 
Perform the following to download the Cygwin software:
  • Navigate to http://www.cygwin.com and click on "Install or Update Now!" to download setup.exe to your machine.
  • Run setup.exe and click Next, which will bring up the Choose Installation Type screen.
  • Choose Option 2, Download without Installing.
  • Click on Next to go through the next few screens, where you will be asked to choose the directory to store the packages (called the Local Package Directory), your Internet connection type, and a download site.


  • Ensure that the 'Hide Obsolete Packages' check box is unselected.
  • Click on Next again to download the full set of files (required with the latest Cygwin 1.7.1 or higher for use with EBS R12) 
4-Install Cygwin
Once the download is complete, perform the following steps to install Cygwin:


  • Launch setup.exe again to conduct the install.
  • From the Choose Installation Type screen, choose Option 3, Install from Local Directory.
  • Click Next, and specify the Root Directory where you wish to install Cygwin (created in Step 2), and DOS as the Default Text File Type.
  • Click Next and specify the same Local Package Directory from Step 3.
  • Click Next to get to the Select Packages screen.



    • Ensure that the 'Hide Obsolete Packages' check box is unselected.
    • Click on Next again to conduct the installation
    5- Verify Package Versions 
     Verify that the versions of packages such as cygwin and make are supported for use with Oracle E-Business Suite Release 12 .
    If the make utility is not the correct version (3.80 for Cygwin), perform the following to update the specific package:
    Copy the gnumake executable built in the previous step to the Cygwin bin directory

     6- Download and install MinGW make if required
     If you don't have or are unable to obtain the version of Cygwin make noted above, use the following instructions to obtain the MinGW make (3.81) utility instead:

    • Go to: http://sourceforge.net/projects/mingw/files/
    • Scroll down and select the MinGW -> make folder on this web page
    • Open make-3.81-20090914-mingw32
    • Copy make-3.81-20090914-mingw32-bin.tar.gz to a location on your local hard drive and extract the files
    • Copy the file MINGW32-MAKE.EXE executable to the bin subdirectory under your cygwin Home and rename it as gnumake.exe
    7- Add Cygwin Bin Directory to Path 
    Add the cygwin bin directory to the system path. For instance:

    C:\> set path = %path%;C:\cygwin\bin
