The MegaWave2 Compiler

The MegaWave2 Compiler is activated by the macro cmw2 (see description Section 5.1). Let us suppose that you are in the directory $MY_MEGAWAVE2/src/test (i.e. the group is test) and that you call cmw2 mod (i.e. the module is mod, coded in the file mod.c). If no error occurs, cmw2 mod processes the following items:

• A file object is created which contains the code of the module for the architecture of the machine; this object is added to a user library called libmymw.a.
• If cmw2 has been called with the -X option (which means: prepare this module for XMegaWave2), an object is created which makes an interface between the module function and XMegaWave2; this object is added to a user library called libmyxmw.a.
• A document skeleton is created in the directory MY_MEGAWAVE2/doc/obj, which has the name mod.doc. This document will be included into the volume 3 of the MegaWave2 guides; it explains the use of the module (syntax of the command, synopsis of the function, input/output objects, ...).
• A command is generated and compiled for the architecture of the machine. The executable allows to run the module as a Unix command. The input/output variables of the module are read or written using files, keyboard or screen. The command is compiled using standard C libraries and the following libraries: mymw, sysmw, W_X11R4, mw, tiff or notiff. They allow the module to access to functions of the System Library, of all the public modules, of all your private modules and of the Wdevice facilities (window toolkit). If there are shared libraries for your machine architecture, you will save a lot of disk space.
