Visual Studio (Freeware version)

Visual Studio Community 2013

Step 1

You need :

Download Visual Studio Community 2013

Visual Studio Community 2013 is a "freeware"
SVN client (http://tortoisesvn.net/downloads)
GIT client (https://git-for-windows.github.io/)

Checkout the Scilab sources (see instructions here).

Creates a d:\GIT-scilab-master directory

d:
mkdir d:\GIT-scilab-master
cd d:\GIT-scilab-master
git clone git://git.scilab.org/scilab
cd scilab\scilab

(Step 2 - Windows 64)

If you wish to compile/build an x64 version, you may need an x64 cross-compile setup (usually shipped with Visual Studio).

Step 3

Checkout the Windows prerequisites for compilation in d:\GIT-scilab-master

cd scilab
svn export --username anonymous --password Scilab svn://svn.scilab.org/scilab/trunk/Dev-Tools/SE/Prerequirements/Windows/

Step 4

Copy the content of the newly created "Windows" directory in "scilab" (d:\GIT-scilab-master\scilab\scilab) directory.

Step 5

Set the SCILAB_JDK and SCILAB_JDK32 environment variables in Windows to point to your JDK installation. This is required for the Ant scripts to be able to compile the Java components.

Step 6

Build Scilab source code using the f2c solution (Scilab_f2c.sln) in Visual Studio or use msbuild.exe.
