The VEGA package is available in different archives:
Vega_XX_Irix6.2.tar.gz |
SGI IRIX 6.2 executable |
Vega_XX_Win32.zip |
Windows 9x/NT executable |
Vega_XX_Linux_x86.tar.gz |
Linux x86 executable |
Vega_XX_Amiga.lha |
AmigaOS 68k executable |
Vega_XX_Source.tar.gz |
ANSI C source code |
where XX is the release number of each archive. You you can download only the package for your system, because each archive contains all the files needed, but not the source code that is provided in a separate archive.
This section of the manual shows the steps needed to install the VEGA package on Unix-like operating systems (e.g. IRIX, Linux, NetBSD, etc). If your operating system is not directly supported by Authors, you must download and compile the source code (Vega_XX_Source.tar.gz archive).
2.1.1 Building the VEGA package
The high portable source code allows to build the package virtually for any computer platform that has a standard ANSI C compiler. It is possible to find some minor compiling problems due to hardware differences. If you cant solve these problems, please contact the Authors.
As first step, you must unpack the Vega_XX_Source.tar.gz file, using the gzip command. If this command is not available in your system, you can download it from any GNU software archive (see: http://www.opensource.org). The correct syntax is:
gzip d Vega_XX_Source.tar.gz
the unpacked file (Vega_XX_Source.tar) created by gzip must be dearchived with tar command:
tar xvf Vega_XX_Source.tar
A directory called Vega will be created. Change your current directory and edit the makefile with your preferred program. Some remarks can help you in this operation. Please set the CC variable to the compiler name (usually cc or gcc) and the CFLAGS variable for the best optimization (e.g. O s).
At this point, run make and the VEGA executable is compiled for your system. The makefile was successfully tested with SGI cc and gnu C (gcc for Linux, gcc for AmigaDOS) compilers.
2.1.2 Setting-up your Unix system
If the downloaded package has been specifically developed for your operating system, you must unpack it using the following two commands:
gzip d Vega_XX_MyOS.tar.gz
tar xvf Vega_XX_MyOS.tar
If you have GNU tar, you can even do it in one step only:
tar Zxvf Vega_XX_MyOS.tar.gz
Please note that the pathway where the archive has been unpacked, is
the real installation pathway.
The next step is the editing of your shell start-up script (e.g. .cshrc for csh or
tcsh, .bashrc for GNU bash) in order to set the environment variable VEGADIR
to the installation pathway. For csh or tcsh shell, you must type:
setenv VEGADIR <INSTALLATION_PATH>
Its strongly recommended to add the installation directory pathway in the command search variable path, defined in the shell startup script.
2.2 Windows 9x/NT installation
This version is a true Win32 console application and thus cant be
executed under Ms-Dos or Windows 3.x operating systems. VEGA Win32 supports correctly long
filenames, Windows threading system and works fine with Windows 95, 98 and NT operating
systems. The Win32 package has been compiled using the standard Pentium ® instruction
set. In order to increase the performances, the code can be optimized with P6 instruction
set (Pentium ® Pro, II, III and AMD K6 ®), simply recompiling the package.
To install the Vega_XX_Win32.zip package, you must unpack this file in the final
installation directory (e.g. C:\Program Files\Vega), using WinZip software. If dont
have this utility, please download the shareware version from http://www.winzip.com. Dont use the old pkunzip.exe
Ms-Dos command, because it doesnt support long filenames.
After this step, you edit the AUTOEXEC.BAT file adding the following line:
SET VEGADIR=<YOUR_INSTALLATION_PATH>
e.g. SET VEGADIR=C:\PROGRA~1\VEGA
Its strongly recommended to add the installation directory to the command search system using the PATH command present in your AUTOEXEC.BAT. Please use the semicolon (;) to limit each entry (e.g. PATH C:\WINDOWS;C:\WINDOWS\COMMAND;C:\PROGRA~1\VEGA).
System requirements needed to run the AmigaDOS version of VEGA:
To install this version of VEGA package, you must unpack the distribution archive using lha command from the command shell:
lha x Vega_XX_Amiga.lha
A directory called Vega will be automatically created. If you dont have lha, you can download it from Aminet. As for Unix systems, you must add in the user-startup file (placed in s directory of your boot disk) the following line:
SetEnv VEGADIR <INSTALLATION_PATH>
Instead of the user-startup modification, you can create a new text file in ENVARC: directory containing a single line with the installation pathway. If you want to add VEGA to your standard command pathway, you can add in the user-startup the following line:
Path <INSTALLATION_PATH> Add
As final step, reboot your computer. Please note that VEGA for Amiga can accept AmigaDOS and Unix-like pathway specification. Use the specific VEGA version for the CPU installed in your system:
Version | CPU |
VEGA.000 | 68000, 68010 and any other CPU without FPU |
VEGA.020 | 68020 and 68030 with 68881/2 FPU |
VEGA.040 | 68040 and 68060 |
The PowerPC CPUs are not supported.
