GSview Readme

GSview 4.8 PostScript previewer. Needs Ghostscript 7.04 or later.
Release date: 2006-02-25

Table of contents


GSview is a graphical interface for Ghostscript under MS-Windows, OS/2 and Unix. Ghostscript is an interpreter for the PostScript page description language used by laser printers. For documents following the Adobe PostScript Document Structuring Conventions, GSview allows selected pages to be viewed or printed. GSview requires Ghostscript 7.04 - 9.99.

Features include:

Changes in version 4.8:

GSview was written by Russell Lang at Ghostgum Software Pty Ltd.


First uninstall any previous versions of GSview.


Obtain GSview (gsv48w32.exe) from

Obtain AFPL Ghostscript 8.53 (gs853w32.exe) from

First install the AFPL Ghostscript self extracting archive gs853w32.exe (or a later version if available) Then install the GSview self extracting archive gsv48w32.exe. Run GSview.

Win32 location details

By default, GSview is installed in the directory c:\Program Files\Ghostgum, which creates the sub-directories c:\Program Files\Ghostgum\gsview and c:\Program Files\Ghostgum\pstotext. The GSview executable is c:\Program Files\Ghostgum\gsview\gsview32.exe.

By default, AFPL Ghostscript is installed in the directory c:\gs, which creates the sub-directories c:\gs\gsN.NN and c:\gs\fonts. The AFPL Ghostscript executables are c:\gs\gsN.NN\gswin32c.exe for console mode and c:\gs\gsN.NN\gswin32.exe for windowing mode.

GSview normally locates AFPL Ghostscript using registry entries created by the AFPL Ghostscript setup program. If these do not exist, GSview will assume that Ghostscript is in an adjacent directory to GSview, usually c:\Program Files\Ghostgum\gsN.NN and c:\Program Files\Ghostgum\fonts.

Win64 (AMD64)

Obtain GSview (gsv48w64.exe) from

First install the AFPL Ghostscript self extracting archive gs853w64.exe (or a later version if available) Then install the GSview self extracting archive gsv48w64.exe. Run GSview.

This version requires that you have a 64-bit x64 processor (AMD64 or EM64T), and that you are also running a 64-bit version of Windows such as Windows XP x64 Edition. It will not run on the more common 32-bit Windows XP.


Obtain GSview ( from

Obtain AFPL Ghostscript 8.53 ( from

Unzip GSview to a temporary directory, change to the gsview2 subdirectory, place (or a later version) in the same directory, and then run os2setup.exe.

If you do not already have EMX installed on your system, you will also need to obtain the EMX Run Time library,, from one of

If GSview refuses to run at all, make sure you do not have an old version of the emx DLL on your system.

GSview (gvpm.exe) will run under OS/2 2.1 and OS/2 Warp.


Use the older GSview 2.7 and Aladdin Ghostscript 4.03.


This has not been tested by Ghostgum Software Pty Ltd. First you will need to recompile GSview and Ghostscript with Microsoft Visual C++ 5. Later versions will not work with Win32s.

For MS-Windows 3.1, it is recommended that you use the Win32 version. You must have Win32s installed before installing GSview. See or GSview and Ghostscript will not work with some versions of Win32s. If it doesn't work with your version, try updating to a later version of Win32s. Some computers will work with Win32s v1.15, others will not.

For Win32s, you will need to manually install both GSview and AFPL Ghostscript. The included setup programs will not run under Win32s. The self extracting archives can be unpacked with Info-ZIP unzip.


Copy gsview, gsview-help, epstool and pstotext to a directory on your search path. Copy gvx*.htm to the directory /usr/share/doc/gsview-N.N. Copy printer.ini to directory /etc/gsview. GSview stores configuration information in $HOME/.gsview.ini.

You must have the shared object version of Ghostscript 7.04 - 9.19, which should be included in recent GNU/Linux distributions. If you don't have the ghostscript shared object, you must first install Ghostscript, then the additional shared object files. To build the ghostscript shared object files, use './configure ; make so'

A precompiled version is available for GNU/Linux. GSview can also be compiled for SunOS and SGI IRIX.


Make sure that the zip/exe files are transferred in binary mode.

The Ghostscript fonts are used by Ghostscript alone. Your system Fonts folder will not be modified.

If you don't like automatic installation programs, it is possible to install GSview and Ghostscript manually. For Ghostscript, read the file gsN.NN\doc\Install.htm. For GSview, read the file gsviewen.hlp

If you wish to use install GSview without any prompts, give a destination directory on the command line. For example:

setup "c:\Program Files\ghostgum"

This will not prompt for a destination directory and will overwrite files without asking.

Configuration of GSview will occur the first time it is run.

See the on-line help for more details. The 'Common Problems' topic is worth reading if GSview doesn't work.


To compile GSview for Windows you need MS Visual C++ 5, 6, 7 or 7.1. Copy srcwin/win.mak to Makefile, edit Makefile to set VCVER and DEVBASE as required, then type 'nmake'. To build for Win64 use 'nmake VCVER=71 WIN64=1'

To compile GSview for OS/2 you need IBM NMAKE.EXE and EMX/GCC 0.9d. To create the GSview online help you need the IBM toolkit. Copy srcos2/os2.mak to Makefile and edit COMPBASE and EMXPATH as required. Type 'nmake'

To compile GSview for X11/Unix you need gcc and the GTK+ 1.2 toolkit. Unzip the sources as follows to convert the line endings:

  unzip -aa
  unzip -o "gsview-4.8/binary/*"
  cd gsview-4.8
  cp srcunx/unx.mak Makefile
GSview may also be available in a tar.gz file which already has Unix line endings. To install, run make install See the X11/Unix topic for more notes on X11 GSview. For SunOS or SGI IRIX, uncomment the appropriate lines in the makefile. You also be able to use
  rpmbuild -ta gsview-4.8.tar.gz


X11 GSview is written by a novice at X Windows programming. It might have serious problems. The GTK+ toolkit is used for most of the graphical interface, with a very small amount of Xlib.

GSview on Unix uses the Ghostscript shared object. Drawing (especially over a network when using anti-aliased text) should be faster.

Known problems


Suggestions from GTK+ programmers about how to improve GSview.

Bug reports. Use "gsview -d9" to get debugging messages on stdout.


Send bug reports to Russell Lang at Ghostgum Software Pty Ltd, gsview at When reporting bugs, please include the version number and date of GSview (from the Help | About box), the version number of Ghostscript, and the exact wording of any error messages. The text in the "Ghostscript Messages" dialog can be copied to the clipboard and pasted as text (not bitmap please!) into an email message. Do not send me large files (>100k bytes) unless requested. If you get a SYS3175 or GPF, please send the address of the GPF - I can use this to help locate the bug. Please distinguish between bugs in GSview and bugs in Ghostscript, by making sure that the problem only occurs when using GSview, and not when using Ghostscript alone. Don't expect a fast response - the work I'm paid to do has a higher priority. For a list of known bugs, see
