Gambas compiler

Usage

gbc3 [options] [<project directory>]

Overview

Gambas is a free development environment based on a Basic interpreter with object extensions, a mix of Java(tm) and Visual Basic(tm). With Gambas, you can quickly design your program GUI with Qt or GTK+, access database systems like MySQL, PostgreSQL, SQlite or ODBC databases, pilot applications with DBus, translate your program into many languages, create GStreamer, OpenGL or SDL applications, and so on...

gbc3 is the compiler that allows you to compile Gambas projects into architecture-independent bytecode.

-g, --debug: add debugging information

-L, --license: display license

-n, --default-namespace <namespace>: default namespace for exported classes

-p, --two-pass: two-pass compilation to detect more errors

-q --quiet: do not print anything if compilation succeeds

-r, --root <directory>: gives the gambas installation directory
