[gs-devel] Merger of ESP and GPL GhostScript: Completed driver part

[Till Kamppeter]

Hi,

I have now completed the driver part of the merger by updating the build 
system to add all necessary checks for the drivers (especially for CUPS 
Raster and OpenPrinting Vector) and to make selection of drivers to be 
built in much easier. Especially one can also build a GhostScript with 
none of the extra drivers from the contrib/ directory by supplying the 
option "--disable-contrib" to "./confugure".

Other additional options are "--with-drivers" to select drivers and 
"--with-fontpath" to easily add the system's font locations (call the 
system's GhostScript with "gs -h" and add the paths shown in the end of 
the output),

"./configure" also auto-detects whether the X drivers can be modularized.

For correct building of the CUPS filters the definition of the version 
number was moved from src/version.mak to ./configure (or src/configure.ac).

The build rules for Omni I have removed from src/contrib.mak, as 
gdevomni.c is present in the contrib/ directory. So its build rules 
belong into contrib/contrib.mak.

To get from current SVN to the driver-enhanced GhostScript, do in an 
empty directory:

svn co svn+ssh://svn.ghostscript.com/svn/ghostscript/trunk/gs

./autogen.sh --help
./configure --enable-dynamic --disable-compile-inits --with-driver=ALL 
--with-fontpath=/var/lib/defoma/gs.d/dirs/fonts:/usr/share/cups/fonts:/usr/share/ghostscript/fonts:/usr/local/lib/ghostscript/fonts:/usr/share/fonts 

make
sudo make install
gs -h

The "./configure" command line is an example for Ubuntu Feisty. It makes 
all drivers being built and the "--with-fontpath=..." is adapted to 
Ubuntu Feisty. Adapt it to your distro.

Run "./configure --help" for the complete set of options. Run "make 
distclean" before rebuilding with other "./configure" options.

Please everyone test this version. All changes concern the output 
devices and so each change by itself should not break more than some 
output devices. The core PostScript/PDF interpreter is completely 
unchanged in this stage of the merger.

Now we can easily replace ESP GhostScript without loss of any printer 
being supported.

Please tell me whether I can start to upload this into the subversion 
repositories of GPL GhostScript.

Next step will be to add the CUPS extensions into the lib/*.ps files.

Mike, what is still missing on the merger?
