Cygwin tutorial yo install#

Existing Cygwin installation maybe effected by major releases, however if you are installing Cygwin for the first time (clean and fresh installation) then just ignore the setup alert.įinally, select the Cygwin packages you want to install in your computer’s Cygwin installation environment. If there are major release upgrade, it is common to see screens like this. You can always add on more packages to your Cygwin installation later.Ĭygwin setup downloads the latest files and packages from online mirror sites and install them in your local computer. However, by default only a base set of packages are installed.

Download the latest installation file of Cygwin from here and then proceed as illustrated here.Ĭygwin environment and all subsequent updates will be installed via Cygwin Net Release setup program, ensure all packages are install. Follow the tutorials based on these screenshots.

Here is an easy way to install and make Cygwin run in Windows 7 64-bit platform, and how to run Linux applications inside the Windows OS. Read Tutorial: How to install ns-3 in Windows 7 using Cygwin by Jason. In order to run or install native Linux or Unix based simulators like NS2 or NS3 (Network Simulators) and OMNeT++ (not a native though) in Windows (without installing Linux), you will need Cygwin.

Wine, WINdows Emulator, on the other hand is just the reverse application to Cygwin – Wine allows us to run applications developed primarily for Windows OS in other operating systems, say Mac OS or Linux. There is a native integration of Windows-based applications and softwares to work in Linux or Unix like environment, thus it is not necessary to install Linux only to fun your simulating program. Cygwin eliminates the overhead of installing an entire Linux OS for running certain applications. This script could certainly be a lot more robust but it gets the job done for me.Cygwin is a development environment similar to Unix one and has command-line interface to work like in Linux but inside the Microsoft Windows Operating System. This uses the cygwin command, cygpath to convert to a windows style pathname and then convers \ to / before calling perl. # finally the command is to call perl with the name of the script and the args. # shell makes a first pass at removing the \. # but then we have to swap \ for / (extra \ needed because the # cygpath does the /cygwin/d/ to d:/ conversion If test "`echo $var | grep '/'`" = "$var" # This routine translates the path name to something of type d:/ # So, we put #!/usr/local/bin/perl in the perl script and this is called # "cygwin style" paths to the program in the #! statement and ActiveState # This is necessary to make perl work with cygwin. The first line of my perl scripts looks like: To fix this problem, I use an intermediate shell script instead of the perl exectuable which takes the filename passed, converts it to a windows style pathname and then calls perl to process the script. If you are running from DOS everything is ok as this looks like:Ĭ:/perl/bin/perl.exe d:/parris/perl/Ĭ:/perl/bin/perl.exe /cygdrive/d/parris/perl/Īnd Perl balks with "no such file" because it can't resolve this pathname. When you try to run a script relying on the #!c:/perl/bin/perl.exe syntax to specify the program that should process the script the shell (in this case cygwin's bash) effectively executes a command like:Ĭ:/perl/bin/perl.exe absolute_script_name The very quick work around which I used for a long time was to always call perl scripts with absolute, windows-style path names (so cygwin does no conversion.) That is:ĭoesn't, even though d:/parris/perl is in the path. ActiveState's perl does not understand this UNIX style names. The problem basically boils down to the fact that cygwin attempts to offer a UNIX like file-system structure where absolute path names start with / instead of a windows style (e.g. The cygwin folks also recommend getting a cygwin implementation of Xemacs. I had already invested time in building my tools based on ActiveState (which has a richer set of add-ins, like modules). This page offers some tips on getting ActiveState's PERL to work within a cygwin environment.įirst, many folks recommend using a cygwin version of Perl if you are going to use cygwin as it avoids some of the problems I have addresed below. Many are also using cygwin to have a UNIX-like environment. Some of us are using PERL on our Windows boxes to process data, etc.
