ghostscript-9.23

Ghostscript の概要

Ghostscript は、PostScrit データに対する万能なプロセッサーであり、PostScript をさまざまに異なる書式に変換する機能を提供します。 これは cups の印刷機能の一部として必須のものです。

本パッケージは LFS-8.3 において正しくビルドでき動作することが確認されています。

Ghostscript のインストール

[注記]

注記

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.

GPL 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 GPL Ghostscript to link to them.

If you have installed the recommended dependencies on your system, remove the copies of freetype, lcms2, libjpeg, and libpng:

rm -rf freetype lcms2 jpeg libpng

Compile Ghostscript:

rm -rf zlib &&

./configure --prefix=/usr           \
            --disable-compile-inits \
            --enable-dynamic        \
            --with-system-libtiff   &&
make
[注記]

注記

The shared library depends on GTK+-3.24.0. It is only used by external programs like asymptote-2.47, ImageMagick-7.0.8-10, and texlive-20180414.

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.

root ユーザーになって以下を実行します。

make install

If you want the shared library too:

make soinstall &&
install -v -m644 base/*.h /usr/include/ghostscript &&
ln -v -s ghostscript /usr/include/ps

Now make the documentation accessible from the normal place:

ln -sfvn ../ghostscript/9.23/doc /usr/share/doc/ghostscript-9.23  &&
sudo cp -a examples/ /usr/share/ghostscript/9.23/

If you have downloaded the fonts, unpack them to /usr/share/ghostscript and ensure the ownerships 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/9.23/examples , for example (you need an X window system display):

gs -q -dBATCH /usr/share/ghostscript/9.23/examples/tiger.eps

コマンド説明

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-4.0.9.

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 -v -s ghostscript /usr/include/ps: Some packages expect to find the interface headers in an alternate location.

ln -sfv ../ghostscript-9.23/doc ... : This puts a symbolic link to 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-2.2.8 libraries if you have installed those.
