Setup Indy SDK build environment for Windows¶

Build Environment¶

Setup a windows virtual machine. Free images are available at here
Launch the virtual machine
Download Visual Studio Community Edition 2017 (these instructions also work with Visual Studio Professional 2017)
Check the boxes for the Desktop development with C++ and Linux Development with C++
In the summary portion on the right hand side also check C++/CLI support
Click install
Download git-scm for windows here
Install git for windows using:
1. Use Git from Git Bash Only so it doesn’t change any path settings of the command prompt
2. Checkout as is, commit Unix-style line endings. You shouldn’t be commiting anything anyway but just in case
3. Use MinTTY
4. Check all the boxes for:
  1. Enable file system caching
  2. Enable Git Credential Manager
  3. Enable symbolic links
Download rust for windows here
1. Choose installation option 1

cd Downloads

git clone https://github.com/hyperledger/indy-sdk.git

It really doesn’t matter where you put these as long as you remember where so you can set the environment variables to this path

Download http://www.sqlite.org/2017/sqlite-amalgamation-3180000.zip

Create an empty static library project in Visual Studio and add sqlite.c file and 2 headers from extracted archive. Then just build it.

Follow to http://zeromq.org/intro.

Download sources from last stable release for Windows.
Open zeromq-x.x.x/builds/msvc/vs2015/libzmq.sln with Visual Studio
If necessary change solution platforms on x64(if you are working on x64 arch).
On main menu bar choose build->build libzmq.
If build project was successful, two files libzmq.dll and libzmq.lib should appear in path zeromq-x.x.x/bin/x64/Debug/vXXX/dynamic.
rename libzmq.lib to zmq.lib.

Get binary dependencies (libamcl*, openssl, libsodium, libzmq, sqlite3).
Put all *.{lib,dll} into one directory and headers into include/ subdirectory.
Open a windows command prompt
Configure MSVS environment to privide 64-bit builds by execution of vcvars64.bat:
```
"C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\"vcvars64.bat
```
Note that depending on the version of Visual Studio placement of vcvars64.bat can be different. For example, it can be "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\amd64\vcvars64.bat"
Execute "C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvars64.bat"
Point path to this directory using environment variables:
- set INDY_PREBUILT_DEPS_DIR=C:\BIN\x64
- set INDY_CRYPTO_PREBUILT_DEPS_DIR=C:\BIN\x64
- set MILAGRO_DIR=C:\BIN\x64
- set LIBZMQ_PREFIX=C:\BIN\x64
- set SODIUM_LIB_DIR=C:\BIN\x64
- set OPENSSL_DIR=C:\BIN\x64
Set PATH to find .dlls:
- set PATH=C:\BIN\x64\lib;%PATH%
change dir to indy-sdk/libindy and run cargo build (you may want to add --release --target x86_64-pc-windows-msvc keys to cargo)

If your windows build fails complaining on gdi32.lib you should edit

  ~/.cargo/registry/src/github.com-*/openssl-sys-*/build.rs

and add

  println!("cargo:rustc-link-lib=dylib=gdi32");

to the end of main() function.

Then try to rebuild whole project.
