Nowadays, on Windows, Net::SSH2 is a much better option and easier to install.

Net::SSH2 is even available via ppm from the sisyphusion repo, and it also ships with the recent Strawberry Perl builds.

Cheers,
Rob

Thanks everyone for your replies. I am trying to install Net::SSH2 module now on windows 2008 R2 OS.

As per the instruction provided in the building guide for Win32, I am kind of stuck in step which build libssh2.

BUILDING_WIN32 document suggests the following approach for building libssh2:




============================================================
* Build libssh2
Download the latest libssh2 from:
    http://libssh2.org/
Unpack it and go into it:
    tar zxvf libssh2-1.4.2.tar.gz
    cd libssh2-1.4.2
Note the directories where you built OpenSSL and zlib, I will use mine
+ in the following example.
Build libssh2:

    ./buildconf
    ./configure --with-openssl --with-libz \
        --with-libssl-prefix=/c/Users/rkitover/src/openssl-1.0.1c \
        --with-libz-prefix=/c/Users/rkitover/src/zlib-1.2.7 \
        --disable-examples-build
    make -j3

The libssh2.a will be in src/.libs .
===========================================================
[download]

when I try to perform ./buildconf on CMD prompt shell, I ended up with below error:

C:\libssh2-1.4.2>sh buildconf
which: libtoolize: unknown command
which: glibtoolize: unknown command
Neither libtoolize nor glibtoolize could be found!
[download]

Later I manually intalled libtooltize tool using 'libtool-1.5.26-setup.exe' and now ending up with below error:

C:\libssh2-1.4.2>sh buildconf
buildconf: line 15: aclocal: command not found
buildconf: line 16: autoheader: command not found
buildconf: line 21: autoconf: command not found
buildconf: line 22: automake: command not found
C:\libssh2-1.4.2>
[download]

I tried installing autoconf and automake similarly but again ending up with multiple compilations issues.
Can anyone suggest how to overcome this issue?
MinGw and MinGW_64 is already configured on host and running fine.
I've successfully done all the previous steps as suggested in http://cpansearch.perl.org/src/RKITOVER/Net-SSH2-0.45/README document

Thanks,
Nikhil.

Any suggestion would be very useful !

Can you guess what this means?

'gzip' is not recognized as an internal or external command, operable program or batch file.

'patch' is not recognized as an internal or external command, operable program or batch file.

I think you need to use  ppm install MinGW before gzip/patch will be available

Thanks for your quick response. MinGw is already installed on host. It gets automatically installed once we open the CPAN for the first time in command prompt. But I installed it again and it got failed on last step:

C:\>ppm install MinGW

I tried again with "perl Makefile.PL machine=none" and got below response now:

MinGw is already installed on host ... Any idea how to overcome this?

Your version of MinGW/gcc is very old, and since the problem is with mingw64 headers, first thing I would try is install a newer MinGW/gcc -- whatever the mingw64 equivalent is of

mingw-get upgrade gcc-core-bin
[download]

I feel your pain unfortunately this module is useless to many people the guy who wrote this needs to remove it or make it clear, the instructions on failure are useless to me and im getting the same as you did you manage to resolve this issue?
