 Cross-compiling for Windows
 ===========================
 
+Cross-compiling on SuSE Linux (Native or WSL)
+---------------------------------------------
+
+1. First add the MinGW Repositories for your SuSE version from:
+
+	* 32 bits: https://build.opensuse.org/project/show/windows:mingw:win32
+	* 64 bits: https://build.opensuse.org/project/show/windows:mingw:win64
+
+2. Get lib3270 sources from git
+
+	* git clone http://softwarepublico.gov.br/gitlab/pw3270/lib3270.git ./v3270
+
+3. Install cross compilers
+
+	* ./v3270/win/install-cross.sh --32 (for 32 bits)
+	* ./v3270/win/install-cross.sh --64 (for 64 bits)
+	* ./v3270/win/install-cross.sh --all (for 32 and 64 bits)
+
+3. Configure build
+
+	* ./v3270/win/win-configure.sh --32 (for 32 bits)
+	* ./v3270/win/win-configure.sh --64 (for 64 bits)
