Re: libssh Installation

[Alberto Garcia <agarciaillera@xxxxxxxxx>]

Compiling libssh in Windows:

Download latest version using git:
git clone https://git.libssh.org/projects/libssh.git libssh

Download and install visual studio community 2017
<https://visualstudio.microsoft.com/downloads/> and Cmake
<https://github.com/Kitware/CMake/releases/download/v3.14.0-rc1/cmake-3.14.0-rc1-win64-x64.msi>
.

libssh has some dependencies. The most important one is OpenSSL. You can
get the precompiled headers form here
<https://www.npcglib.org/~stathis/blog/precompiled-openssl/>. Make sure you
download the VS2017 one.

Now you are ready to create the project that you will be able to compile in
VS.

cd libssh
mkdir build
Now open cmake GUI and just set:
source to your libssh path
where to build to the just created build path

And click configure.

Here is a screenshot of my CMake configuration. Make sure you uncheck
WITH_ZLIB (unless you compile it by your own) and set LIB_EAY_RELEASE
to libcryptoMT.lib path and SSL_EAY_RELEASE to libsslMT.lib.

Now you can click on generate and open the project. It will open it up in
VS2017.

Lastly, in VS you should right click on ssh_static (or ssh_shared if you
want to generate a dll) at the Solution Explorer at the right -> properties
-> C/C++ -> Code Generation -> Runtime Librariy -> /MT

and  properties -> C/C++ -> Preprocessor -> Preprocessor definitions ->
properties -> C/C++ -> add HAVE_OPENSSL_CRYPTO_CTR128_ENCRYPT;

Make sure that you select the Configuration (Debug, release...) that you
want to build the library in.

Just right click again in the project name and click on Build.

You will have a .lib (if you built the static version) or a .lib and .dll (
in the case you built the shared one).

You can include those libs plus the include folder in your project and
start using libssh.


Let me know it it is clear enough
