Installation¶

The software consists of a single executable (operating system dependent) to be used at the command prompt of a Terminal window or in batch scripts.

Operating Systen	Executable
Linux (64)	gfzrnx_lx64-x.x.x
Linux (32)	gfzrnx_lx32-x.x.x
SunOS (Sparc)	gfzrnx_sun-x.x.x
SunOS (i86)	gfzsun_suni86-x.x.x
MS Windows 11 (64)	gfzrnx_win11_64-x.x.x.exe
MS Windows 10 (64)	gfzrnx_win10_64-x.x.x.exe
MS Windows 7,8 (64)	gfzrnx_win64-x.x.x.exe
MS Windows 7,8 (32)	gfzrnx_win32-x.x.x.exe
Mac OSX (64)	gfzrnx_osx64-x.x.x
Mac OSX (arm64, Mx)	gfzrnx_osxarm64-x.x.x
Linux-ARM (64)	gfzrnx_armlx64-x.x.x
Linux-ARM (32)	gfzrnx_armlx32-x.x.x

UNIX¶

Put the executable to a directory of the search path $PATH. Simply run the following command to show the elements of your search path $PATH. This search path can differ depending on your overall setup.

> echo $PATH
/opt/local/bin:/opt/local/sbin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/opt/X11/bin

Copy the executable into a directory covered by your system search $PATH variable and create a symbolic link gfzrnx for the ease of use. Here is an example using e.g. /usr/local/bin and the downloaded executable gfzrnx_osxarm64-1.16-8154:

> sudo copy gfzrnx_osxarm64-1.16-8154 /usr/local/bin
> sudo chmod a+x gfzrnx_osxarm64-1.16-8154
> cd /usr/local/bin
> sudo ln -s gfzrnx_osxarm64-1.16-8154 gfzrnx

The which command should show up with the search fullpath of the gfzrnx-command.

> which gfzrnx
/usr/local/bin/gfzrnx
> gfzrnx -h

MS Windows¶

Create a symbolic link gfzrnx.exe in your C:\Windows to the real executable location (e.g. c:\Users\user\gfzrnx_1.16-8154_win10.exe). This allows you now to use the short command name gfzrnx.exe or simply gfzrnx.

Open cmd.exe as Administrator (right mouse click on cmd.exe).

C:\Users\user > cd c:\Windows
C:\Windows    > mklink /J gfzrnx.exe c:\Users\user\gfzrnx_1.16-8154_win10.exe

windows_install

Temporary Directory¶

The gfzrnx will store and execute libraries in a temporary directory.

OS	Default Temporary Directory
UNIX	/tmp
Windows	$WINDIR (C:\Windows)

If this is not an option for you, you can specify an alternative temporary directory via the environment variables $TEMP or $TMP on all platforms.
