<h1>Setting SWT windows native build setup</h1>

<h3>Software needed for setting up windows native build</h3>
<ol>
<li><p> Microsoft 'Visual Studio - Community 2019' and 'Windows 10 SDK', link to <a href="https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=Community&rel=16">download page</a></p>
	<ul>
	<li>Run the web installer.
	<li>Go to "Desktop development with C++".
	<li>Select/turn the check-box ON for below items from the list:
		<ul>
		<li>VC++ 2019 v141 toolset(x86, x64)
		<li>Windows 10 SDK (10.0.16299.0) for Desktop C++
		</ul>
		<p>Note: [Version numbers (v141, 10.0.16299.0) mentioned above get revised as per latest Microsoft 'Visual Studio' update.]</p>
	</ul>
<li><p> JDK8 64bit link to <a href="http://www.oracle.com/technetwork/java/javase/overview/java8-2100321.html">Oracle JDK</a> or <a href="https://developer.ibm.com/javasdk/downloads/">IBM JDK</a></p>
<li> Cygwin [Optional for local setup]</p>
</ol>
<p>Note: [Eclipse SWT Windows moved to latest "Win10 SDK" and "Visual Studio 2019 community edition" 
via bugzilla <a href="https://bugs.eclipse.org/bugs/show_bug.cgi?id=572308">bug 572308</a>]</b></p>

<h3>Steps to set up Windows native build:</h3>
<ol>
<li>[Optional for local setup] Install and configure Cygwin SSH Server on Windows.
<p> Note: Make sure 'openssh' package is also installed.</p>
<p> For more details on how to configuring SSH refer: <a href="http://docs.oracle.com/cd/E24628_01/install.121/e22624/preinstall_req_cygwin_ssh.htm#CHDJDBIA">link</a></p>

<li>[Optional for local setup] Configure the machine for password-less SSH authentication with the Hudson machine.
<p> For more details you can refer: <a href="http://users.cecs.anu.edu.au/~xzhang/pubDoc/IT/SSH%20without%20password%20from%20Windows.htm">public guide</a></p>
<p> Sharing some key steps below(which I recall):</p>
<ul>
<li><p> Generate the 'dsa' public/private key from your "swtbuild" account from windows machine.</p>
<li><p> Now login to the Hudson machine with "swtbuild" account.</p>
<li><p> Copy the public keys and register then on the Hudson machine.. this should enable password-less authentication.</p>
</ul>

<li><p> 'SWT_BUILDDIR' root directory contain various libraries like Visual Studio libraries, JDK, etc.. </p>
<p> Setup your own 'SWT_BUILDDIR' with below like directory structure:</p>
<ul>
<li><p> Install Visual Studio Community 2019 libraries in default location or in: 'SWT_BUILDDIR\Microsoft\Visual Studio\2019'</p>
<li><p> Windows10 SDK gets installed in "Program Files (x86)" directory by default like: 'C:\Program Files (x86)\Windows Kits\10'</p>
<li><p> Install/Unzip JDK8 64bit in 'SWT_BUILDDIR\Java\Oracle\jdk1.8.0-latest\x64'</p>
</ul>

<li> <p> For local testing, Run as Ant build below file with 'build_libraries' as target(assuming <a href="git.php">SWT setup</a> is in place):</p>
<p>${workspace_loc:/org.eclipse.swt.win32.win32.x86_64/build.xml}</p>
<li>[Optional for local setup] Now you can point the Windows hudson job to this machine and trigger a native build.
<p> Note: For testing purpose from hudson, temporarily turn the nativeChanges flag to 'true' to force a native build compilation.</p>
