Building SSF for Windows

Get build dependencies

SSF depends on Boost and OpenSSL libraries. You can choose to build dependencies yourself, or install prebuilt library packages.

Using prebuilt packages

Obtain installers for the libraries and install them:

  • Boost 1.65.1:

Install boost_1_65_1-msvc-14.1-32.exe (32-bit) or boost_1_65_1-msvc-14.1-32.exe (64-bit) from http://sourceforge.net/projects/boost/files/boost-binaries. Replace msvc-14.1 with your version of Visual Studio.

You will then need to point the cmake BOOST_ROOT variable to the location of the boost install (By default: C:\local\boost_1_65_1).

  • OpenSSL 1.0.2m:

Install Win32OpenSSL-1_0_2m.exe (32-bit) or Win64OpenSSL-1_0_2m.exe (64-bit) from https://slproweb.com/products/Win32OpenSSL.html

NOTE: OpenSSL versions 1.1 is currently incompatible with Boost. The latest compatible prebuilt version of OpenSSL is 1.0.2l.

If you have not installed OpenSSL in the default directory (C:\OpenSSL-Win32 for C:\OpenSSL-Win64), you will need to point the cmake variable OPENSSL_ROOT_DIR to the install location.

Building dependencies yourself

Boost and OpenSSL dependencies will need to be built manually. Convenience scripts for automatically building these can be found in the builddeps directory.

7-Zip is required to decompress the source tarballs.

First prepare a build directory, download boost and openssl source and place them inside the build directory:

C:\Users\user> mkdir C:\build
C:\Users\user> cd C:\build

Boost 1.65.1 can be downloaded from https://dl.bintray.com/boostorg/release/1.65.1/source/boost_1_65_1.tar.bz2 and OpenSSL 1.0.2m from https://www.openssl.org/source/openssl-1.0.2m.tar.gz

Building boost

Build Boost using build_boost.bat

C:\build> C:\path_to_ssf_source\builddeps\build_boost.bat C:\Users\user\Downloads\boost_1_65_1.tar.bz2 1_65_1 32 C:\boost

Pass 32 for 32-bit or 64 for 64-bit builds. Boost headers and libraries will be installed in C:\boost

NOTE: build_boost.bat will build a version of Boost without C++ RTTI support, when generating the project files prior to building SSF, make sure DISABLE_RTTI is set to ON.

NOTE: build_boost.bat will only build static/runtime static versions of the boost libraries.

Building OpenSSL

A Perl distribution is required for building OpenSSL, you can get Strawberry Perl 5.26.0.2 from http://strawberryperl.com.

The netwide assembler is also required for building OpenSSL. Grab and install NASM from http://www.nasm.us/.

Make sure perl.exe and nasm.exe can be found in your environment before running the following commands (adjust Path if needed).

C:\build> C:\path_to_ssf_source\builddeps\build_openssl.bat C:\Users\user\Downloads\openssl-1.0.2m.tar.gz 1.0.2m 32 C:\openssl

Pass 32 for 32-bit or 64 for 64-bit builds. OpenSSL headers and libraries will be installed in C:\openssl

NOTE: build_openssl.bat will only build the static/runtime static version of OpenSSL.

Building SSF

SSF requires CMake and Visual Studio 2017 (2015 should work as well)

If you obtained the source for the git repository, make sure the submodules are checked out:

C:\path_to_ssf_source> git submodule update --init

Generate the project files with CMake in your build directory. Point the BOOST_ROOT and OPENSSL_ROOT_DIR variables to the correct location (or leave empty for default settings).

C:\build> cmake C:\path_to_ssf_source -DBOOST_ROOT=C:\local\boost_1_65_1  -DOPENSSL_ROOT_DIR=C:\OpenSSL-Win32 -DUSE_STATIC_LIBS=ON

Various parameters can be customized when generating the project files:

  • USE_STATIC_LIBS: ON or OFF to enable/disable linking statically against boost and OpenSSL. On windows, you want this to be ON in most of the cases.
  • USE_STATIC_RUNTIME: ON or OFF to enable/disable linking statically against the C++ runtime library (msvcrt). This is set automatically to the same value as USE_STATIC_LIBS.
  • BUILD_UNIT_TESTS: ON or OFF to enable/disable building SSF unit tests.
  • DISABLE_RTTI: ON or OFF to disable/enable C++ Run-Time Type Information. RTTI is enabled by default. Only disable RTTI if boost libraries have been built without RTTI.
  • DISABLE_TLS: ON or OFF to disable/enable TLS layer. Network traffic will use raw TCP and be left unsecured. Provided for testing purpose only.

Proceed to build SSF:

C:\build> cmake --build . --config Release

Binaries are located in: src\client\Release\ssf.exe, src\client\Release\ssfcp.exe and src\server\Release\ssfd.exe.

Replace Release with Debug for debug binaries.
