LiteSpeed QUIC (LSQUIC) Client Library - Building for Windows

Description

This document is intended to supplement the document README.md at the root of the distribution of the LiteSpeed QUIC (LSQUIC) Client Library to build the library and programs in a Windows environment.

The addition of Windows support to the LSQUIC Client was a contribution from the user community and this document was based on our experiences of validating the code. As for the overall implementation, do not hesitate to report bugs back to us. Even better, continue to send us fixes and improvements - it makes the code better for everyone.

Preliminaries

It it recommended that the installer have experience with Windows development, Visual Studio, and open source projects in Windows. These instructions assume a general build, primarily for 64-bit, both of a debug and a release version.

Some open source code required to be installed to build the code include:

The Git version control system executable for Windows.
A version of the Visual Studio development environment for Windows.
The Windows SDK and C++ must be installed from it. The Visual Studio Community Edition will be just fine.
cmake for Windows. Download and install the version appropriate for the development/target platform (32 vs 64-bits, etc.).
The Windows vcpkg package manager. It can be cloned from here. Clone it at the same level to be used to clone/develop the lsquic-client. The package must be compiled following the instructions on the git repository.
Perform builds using the Developer Command Prompt for Visual Studio instead of the regular cmd.exe.
Once the package manager has been built, it must be used to install and build some open source projects. Before doing that, an environment variable must be defined which specifies how the package should be built. The easiest way would be to add it into the system environment variables in the System applet of the Windows Control Panel. This example assumes 64-bit static libraries will be built, which is what is generally recommended:
```
VCPKG_DEFAULT_TRIPLET=x64-windows-static
```
From the command line, once the variable above has been defined, install both zlib and libevent. Note that libevent may also automatically install openssl. If it does not, it may need to be manually specified to properly link the lsquic-client executables.
```
vcpkg install zlib:x86-windows-static
vcpkg install libevent:x64-windows-static
vcpkg integrate install
```

Clone and compile boringssl. It can be cloned from here.

git clone https://boringssl.googlesource.com/boringssl
cd boringssl
cmake -DCMAKE_GENERATOR_PLATFORM=x64 --config Debug -DBUILD_SHARED_LIBS=OFF -DOPENSSL_NO_ASM=1 .
msbuild ALL_BUILD.vcxproj
set boringssl=%cd%

Visual Studio can be run, and the project opened within the boringssl directory. Set the solution configuration to Debug and the solution platform to 64-bit. Compile the project.
Repeat the cmake and compile steps replacing Debug with Release.

Make and Compile LSQUIC-Client

Clone lsquic-client:

git clone https://github.com/litespeedtech/lsquic-client.git
cd lsquic-client

Configure the build using cmake (you can specify Release instead of Debug to build an optimized version of the library, but that won't build tests):

cmake -DCMAKE_GENERATOR_PLATFORM=x64 -DBUILD_SHARED_LIBS=OFF ^
     -DVCPKG_TARGET_TRIPLET=x64-windows-static -DCMAKE_BUILD_TYPE=Debug ^
     -DCMAKE_TOOLCHAIN_FILE=c:/tools/vcpkg/scripts/buildsystems/vcpkg.cmake ^
     -DBORINGSSL_DIR=%boringssl% .

Compile everything (add /m flag if you have processors to spare):

msbuild ALL_BUILD.vcxproj

http_client.exe should be found in the Debug (or Release) directory.

Run tests (assuming Debug build):

msbuild RUN_TESTS.vcxproj

Have fun,

LiteSpeed QUIC Team.
