Compiling libssh2 on windows

Some one can help me to compile libssh2 on windows with Visual Studio 2017. The only things I found are too old and outdated.

I downloaded libssh2 from github and run cmake libssh2 and then cmake -P cmake_install.cmake but can't find INSTALL file "libssh2.lib".

And I'm stuck here!

******** Update 1 ***********

Crypto_backend is missing, I trying to compile with openssl and get a lot of unresolved symbols.

******** Update 2 ***********

Ok! I used the cmake-gui and get rid of the unresolved symbols but now I'm having issues with some header files. libssh2 var types are not defined. Some kind of include missing....?

Solution

  • I could compile libssh2 in a Windows 10 environment (I was intrigued).

    Environment:

    • Windows 10 x64.
    • Visual Studio Community 2017 version 15.2 (26430.4) Release.
    • CMake version 3.9.0-rc5 ( I had to uninstall a previous version manually before install the last version because the installer has changed, as the cmake web suggests).
    • Git version 2.10.1.windows.1

    If you request any other crypto backend libraries than WinCNG , I am afraid you need to compile previously that crypto backend library before any attempt to compile libssh2 and make sure CMake find automatically the crypto-backend-library (if not, check for requested cmake variables and fulfill manually).

    Steps in cmd to compile libssh2 using WinCNG and dynamic library option:

    cd where/you/like/to/install
git clone https://github.com/libssh2/libssh2.git
cd libssh2
mkdir dll <-- directory to install libssh2
cmake -DCRYPTO_BACKEND=WinCNG -DBUILD_SHARED_LIBS=ON -DCMAKE_INSTALL_PREFIX=./dll --build .
cmake --build . --target install

    And et voilà, after less than a minute, libssh is created and installed in dll directory.

    I hope that this miniguide could help you.
