Install Genero Web Application

To build and package Genero Web applications, you must first install Genero Web Application (GWA).

Before you begin:

The installation and licensing of Genero products requires you to read and accept the End User License Agreement, which can be found on the Four Js website at https://4js.com/end-user-license-agreements/.

Important:

The Genero Web Application and Genero BDL X.YZ versions are interdependent in terms of pcode compatibility: To build a GWA 5.01 embedded app, the source code needs to be compiled with Genero BDL 5.01.

Download Genero Web Application from the Four Js Web site.
The Genero Web Application product is delivered as a zip that can be unzipped either to the FGLDIR or to a separate directory. The recommended installation is to unzip it directly over FGLDIR. Examples of both installation methods are given here.
The zip file will contain all tools to build the final GWA application. Notice that those tools are written in Genero and require a valid Genero BDL 5.01 or greater to be installed.
Install Genero Business Development Language. See Installing Genero BDL for more details.

The preferred installation is to unzip the Genero Web Application package (fjs-gwa-*.zip) directly over FGLDIR.

This has two advantages:

The GWA tools, gwabuildtool, gwarun, and gwasrv, are immediately in the PATH if $FGLDIR/bin is in the PATH already.
The GWA API is immediately available for IMPORT FGL without the need to set FGLLDPATH explicitly.

Install the GWA over FGLDIR.

Extract the content of the Genero Web Application package (fjs-gwa-*.zip) into FGLDIR.

$ unzip -q -o -d $FGLDIR fjs-gwa-*.zip

Install GWA in its own directory

If you need to test several versions of GWA against a single installation of Genero BDL, you will extract each GWA distribution archive to a separate directory.

Install GWA in a directory separate to FGLDIR.

Create a directory (gwa-install-dir) for the GWA installation.
```
$ mkdir /opt/fourjs/gwa-5.01
```
Extract the contents of the Genero Web Application package (fjs-gwa-*.zip) into this directory.
```
$ unzip -q -o -d /opt/fourjs/gwa-5.01 fjs-gwa-*.zip
```
Add the gwa-install-dir/bin directory to your PATH environment variable, in order to find the GWA tools in the path.
```
export PATH=/opt/fourjs/gwa-5.01/bin:$PATH
```
Add the gwa-install-dir/lib directory to your FGLLDPATH environment variable.
You may need the GWA package library during your development, for example, to get the location of windows, or to reload the application.
```
export FGLLDPATH=/opt/fourjs/gwa-5.01/lib:$FGLLDPATH  
```
