Building `libssh2` for Windows (Win32/Win64) is a lot harder than I hoped for

Posted by jpluimers on 2017/05/09

Building libssh2 for Windows (Win32/Win64) is a lot harder than I hoped for.

There were no instructions on their website, there was the occasional “use CMake” at #IRC and that was about it.

Of course running just CMake doesn’t work and getting it working involves a lot of non-descriptive error messages, cursing and fruitless searches for them just bumping into “me too” threads not really providing the solution.

I tried building OpenSSL but after building, no `lib` directory appears so I cannot satisfy the dependencies. Not sure what OpenSSL would bring as I could not find any documentation about it either, so I’ll leave it at that.

Might be that `make test` for OpenSSL doesn’t succeed because some vague non-explained error which is odd when doing this on an almost prestine VS 2015 Community Edition VM.

But I’ll take that up with the OpenSSL people one day.

Oh the joy of Open Source…

Below are the steps (below the –more– mark a gist with the most recent version).

The core are these:

  • you need git, Visual Studio and CMake
  • use CMake to generate project files, msbuild to build (CBuild cannot build any more)
  • After a Win64 build you have to reset the platform to create a Win32 build

These links helped a lot some in the positive, others in the negative sense:

  1. Install Visual Studio 2015 community edition from https://www.visualstudio.com/en-us/downloads/download-visual-studio-vs.aspx (as of writing:http://download.microsoft.com/download/D/2/3/D23F4D0F-BA2D-4600-8725-6CCECEA05196/vs_community_ENU.exe or http://download.microsoft.com/download/b/e/d/bedddfc4-55f4-4748-90a8-ffe38a40e89f/vs2015.3.com_enu.iso )
  2. Download CMake via https://cmake.org/download/ back then https://cmake.org/files/v3.6/cmake-3.6.2-win64-x64.msi
  3. Install and ensure to add CMake to the PATH for all users:

Steps for now (I’m not happy at all on how to get rid of VCRUNTIME140.DLL):

  1. Install Visual Studio 2015 community edition from https://www.visualstudio.com/en-us/downloads/download-visual-studio-vs.aspx (as of writing: http://download.microsoft.com/download/D/2/3/D23F4D0F-BA2D-4600-8725-6CCECEA05196/vs_community_ENU.exe or http://download.microsoft.com/download/b/e/d/bedddfc4-55f4-4748-90a8-ffe38a40e89f/vs2015.3.com_enu.iso )
  2. Download CMake via https://cmake.org/download/ back then https://cmake.org/files/v3.6/cmake-3.6.2-win64-x64.msi
  3. Install and ensure to add CMake to the PATH for all users:

The above trick will create a libssh2.dll that is statically linked with libvcruntime.lib instead of vcruntime.lib which means you do not need to have VCRUNTIME140.DLL or VCRUNTIME140D.DLL on your system.

############################################################################
Summary of testing libssh2 client against opensuse Tumbleweed openssh server
############################################################################
– Server side opensuse Tumbleweed with sshd OpenSSH_7.2p2, OpenSSL 1.0.2j-fips 26 Sep 2016
– default mode (no modifications in /etc/ssh/sshd_config)
– secure mode (applying https://github.com/comotion/gone/blob/github/modules/ssh)
– Client side Windowx 86 with x86 libssh2 dll versions
– libssh2_1.2.6
– libssh2_1.7.0_DEV (without OpenSSL means WinCNG)
– libssh2_1.8.1_DEV (without OpenSSL means WinCNG; with OpenSSL has more ciphers/MACs but requires extra DLLs)
Summary:
– plain libssh2_1.7.0_DEV and libssh2_1.8.1_DEV won't connect to default/secure sshd as there is no matching cipher (so key exchange is working)
– libssh2_1.2.6 only connects to default as secure has too few ciphers
– secure sshd with added “aes256-cbc“ might work for the plain libssh2 DLLs, but there are aes-cbc attacks since 2008: http://www.kb.cert.org/vuls/id/958563
– libssh2_1.8.1_DEV with OpenSSL connects fine
https://www.libssh2.org/
Capabilities and Features
– Key Exchange Methods: diffie-hellman-group1-sha1, diffie-hellman-group14-sha1, diffie-hellman-group-exchange-sha1, diffie-hellman-group-exchange-sha256
– Hostkey Types: ssh-rsa, ssh-dss
– Ciphers: aes256-ctr, aes192-ctr, aes128-ctr, aes256-cbc (rijndael-cbc@lysator.liu.se), aes192-cbc, aes128-cbc, 3des-cbc, blowfish-cbc, cast128-cbc, arcfour, arcfour128, none
– Compression Schemes: zlib, zlib@openssh.com, none
– MAC hashes: hmac-sha2-256, hmac-sha2-512, hmac-sha1, hmac-sha1-96, hmac-md5, hmac-md5-96, hmac-ripemd160 (hmac-ripemd160@openssh.com), none
– Authentication: none, password, public-key, hostbased, keyboard-interactive
– Channels: shell, exec (incl. SCP wrapper), direct-tcpip, subsystem
– Global Requests: tcpip-forward
– Channel Requests: x11, pty, exit-signal, keepalive@openssh.com
– Subsystems: sftp(version 3), publickey(version 2)
– SFTP: statvfs@openssh.com, fstatvfs@openssh.com
– Thread-safe: just don't share handles simultaneously
– Non-blocking: it can be used both blocking and non-blocking
– Your sockets: the app hands over the socket, calls select() etc.
– Crypto backends: OpenSSL, libgcrypt, mbedTLS or WinCNG (native since Windows Vista): builds with either
