Building Sai Builder for windows

The overall flow is

  • build lws - build libgit2 - build sai-builder piggybacking on pthreads built for lws

Building lws

Refer to the instructions in lws for how to install cmake, git and the toolchain on windows also used in the next steps here.

For windows + sai-builder, the following lws cmake config is suitable

> cmake .. -DLWS_WITH_JOSE=1 -DLWS_HAVE_PTHREAD_H=1 -DLWS_EXT_PTHREAD_INCLUDE_DIR="C:\Program Files (x86)\pthreads\include" -DLWS_EXT_PTHREAD_LIBRARIES="C:\Program Files (x86)\pthreads\lib\x64\libpthreadGC2.a" -DLWS_WITH_MINIMAL_EXAMPLES=1 -DLWS_WITH_THREADPOOL=1 -DLWS_UNIX_SOCK=1 -DLWS_WITH_STRUCT_JSON=1 -DLWS_WITH_SPAWN=1 -DLWS_WITH_SECURE_STREAMS=1 -DLWS_WITH_DIR=1

Building libgit2

> git clone https://github.com/libgit2/libgit2.git
> cd libgit2 ; mkdir build ; cd build
> cmake .. -DBUILD_CLAR=OFF
> cmake --build . --config DEBUG

I couldn't get runas to do anything useful, I opened an Admin-privileged cmd window and did

> cd \Users\agreen\libgit2\build
> cmake --install . --config DEBUG
> exit

Building Sai-builder

> git clone https://warmcat.com/repo/sai
> cd sai ; mkdir build ; cd build
> cmake .. -DSAI_MASTER=0 -DSAI_LWS_INC_PATH="\Users\agreen\libwebsockets\build\include" -DSAI_LWS_LIB_PATH="\Users\agreen\libwebsockets\build\lib\Debug\websockets_static.lib" -DLWS_OPENSSL_INCLUDE_DIRS="\Program Files\OpenSSL\include" -DSAI_GIT2_INC_PATH="\Program Files (x86)\libgit2\include" -DSAI_GIT2_LIB_PATH="\Program Files (x86)\libgit2\lib\git2.lib" -DSAI_EXT_PTHREAD_INCLUDE_DIR="C:\Program Files (x86)\pthreads\include" -DLWS_OPENSSL_LIBRARIES="\Program Files\OpenSSL\lib\libcrypto.lib;\Program Files\OpenSSL\lib\libssl.lib"  -DSAI_EXT_PTHREAD_LIBRARIES="C:\Program Files (x86)\pthreads\lib\x64\libpthreadGC2.a"

Configuring Sai-builder

>net user sai /add

As administrator

> mkdir \ProgramData\sai\builder

Then create the config JSON in \ProgramData\sai\builder\conf, using the platform name windows-10.
