Introduction to Ghostscript
Ghostscript is a versatile processor for PostScript data with the ability to render PostScript to different targets. It is a mandatory part of the cups printing stack.
Note
Development versions of BLFS may not build or run some packages properly if LFS or dependencies have been updated since the most recent stable versions of the books.
Package Information
Additional Downloads
If you wish, you can download additional fonts.
Ghostscript Dependencies
Recommended
Cups-2.4.7 (required for building the “cups” device backend, which is needed by cups-filters), Fontconfig-2.15.0 (required, if you are installing any suggested font), FreeType-2.13.2, Little CMS-2.14, libjpeg-turbo-3.0.1, libpng-1.6.40, libtiff-4.6.0, and OpenJPEG-2.5.0
Optional
Cairo-1.18.0, GTK+-3.24.40, libidn-1.42, libpaper-2.1.2, libwebp-1.3.2, and a graphical environment
Installation of Ghostscript
Note
The Ghostscript build system is not user-friendly. In order to use system copies of various graphics libraries, you must do it using unconventional methods.
Ghostscript includes (old) copies of several libraries. Some of these seem to have been patched to fix known vulnerabilities, but others of these copies are less-well maintained. To ensure that any future fixes are applied throughout the whole system, it is recommended that you first install the released versions of these libraries and then configure Ghostscript to link to them.
If you have installed the recommended dependencies on your system, remove the copies of freetype, lcms2, libjpeg, libpng, and openjpeg:
rm -rf freetype lcms2mt jpeg libpng openjpeg
Compile Ghostscript:
rm -rf zlib &&
./configure --prefix=/usr \
--disable-compile-inits \
--with-system-libtiff &&
make
To compile the shared library libgs.so
, run the following additional command as an unprivileged user:
make so
This package does not come with a test suite. A set of example files may be used for testing, but it is only possible after installation of the package.
Now, as the root
user:
make install
If you want the shared library too:
make soinstall &&
install -v -m644 base/*.h /usr/include/ghostscript &&
ln -sfvn ghostscript /usr/include/ps
Now make the documentation accessible from a standard place:
mv -v /usr/share/doc/ghostscript/10.02.1 /usr/share/doc/ghostscript-10.02.1 &&
rm -rfv /usr/share/doc/ghostscript &&
cp -r examples/ /usr/share/ghostscript/10.02.1/
If you have downloaded the fonts, unpack them to /usr/share/ghostscript
and ensure the ownership of the files are root
: root
.
tar -xvf ../ghostscript-fonts-std-8.11.tar.gz -C /usr/share/ghostscript --no-same-owner &&
tar -xvf ../gnu-gs-fonts-other-6.0.tar.gz -C /usr/share/ghostscript --no-same-owner &&
fc-cache -v /usr/share/ghostscript/fonts/
You can now test the rendering of various postscript and pdf files from the /usr/share/ghostscript/10.02.1/examples
. To do this, run the following command (in a X Windows display):
gs -q -dBATCH /usr/share/ghostscript/10.02.1/examples/tiger.eps
Command Explanations
rm -rf zlib : zlib was installed as part of LFS.
--disable-compile-inits
: This option makes gs and libgs.so
slightly smaller.
--with-system-libtiff
: Remove this option if you've not installed libtiff-4.6.0.
install -v -m644 base/*.h... : Some packages (ImageMagick is one) need the Ghostscript interface headers in place to link to the shared library. These commands install the headers.
ln -sfvn ghostscript /usr/include/ps: Some packages expect to find the interface headers in an alternate location.
mv -v /usr/share/doc/ghostscript/10.02.1 /usr/share/doc/ghostscript-10.02.1: This moves the documentation where it is expected to be found.
--disable-cups
: this option will save a tiny amount of space by not linking gs and libgs.so
to the Cups-2.4.7 libraries if you have installed those.
