Downloading Source Code

Today, most of the UNIX and Linux distributions install CUPS by default. CUPS requires ANSI-compliant C and C++ compilers, a Make program and Bourne shell. The GNU compiler tools also work well with CUPS.

CUPS has been tested with GNU Make as well as the other Make programs shipped by Compaq, HP, SGI, and Sun. BSD users should use GNU make (gmake). The latest version of CUPS can be downloaded from http://www.cups.org/software.php. The current stable version of CUPS is 1.3.8.

Apart from these tools, we also require support for the following libraries that provides additional functionality for printing service. CUPS mainly supports two libraries:

CUPS imaging library
CUPS library

The CUPS imaging library consists of libraries for JPEG, PNG, TIFF, ZLIB, and so on, and it is used for images support.

The CUPS library contains CUPS-specific functions that support the use of CDSA, GNU TLS, and the OpenSSL libraries for encryption. We will discuss these in details in Chapter 10, on Security. For the directory service, you can use the OpenLDAP and the OpenSLP libraries.

You can find a mirror of CUPS related libraries which is maintained by Easy Software Products at:

ftp://ftp.easysw.com/pub/libraries.

Note

CUPS can easily compile and run without above libraries. However, you will miss out on many of the features provided by CUPS.

If any changes need to be made in the man pages, you will need GNU Troff (Groff) or another nroff-like package. Groff is available at ftp://ftp.gnu.org/gnu/groff/.

The documentation is formatted using the HTMLDOC software. If you need to make changes, you can get the HTMLDOC software from http://www.htmldoc.org/index.php.

Compiling CUPS

The source code of CUPS is available in two formats:

Gnu zip— with .gz extension
bzip2— with .bz2 extension

Once you download the source code for the CUPS, it must be extracted using the following command:

#tar -xvf cups-1.3.8-source.tar.gz

#tar xvjf cups-1.3.8-source.tar.bz2

In the example above, cups-1.3.8-source.tar.gz is the source code of CUPS in a .gz format. To compile the source code, we need to go to the CUPS source directory which has just been created.

#cd cups-1.3.8

CUPS uses GNU Autoconf to configure the Makefiles and source code for your system. Type the following command to configure CUPS for your system:

#./configure

The default installation will put the CUPS software in the /etc, /usr, and /var directories on your system, which will overwrite all existing print commands on your system.

You can also use the --prefix option to install the CUPS software in another location:

#./configure --prefix=/some/directory

You can see a complete list of configuration options using the --help option:

#./configure -help

If the PNG, JPEG, TIFF, and ZLIB libraries are not installed in a system in the default location (typically /usr/include and /usr/lib), we need to set the CFLAGS,CPPFLAGS, CXXFLAGS, DSOFLAGS and LDFLAGS environment variables prior to configuration:

setenv CFLAGS "-I/any/dir" setenv CPPFLAGS "-I/any/dir" setenv CXXFLAGS "-I/any/dir" setenv DSOFLAGS "-Lany/dir" setenv LDFLAGS "-L/any/dir" ./configure

CFLAGS="-I/any/dir" \ CPPFLAGS="-I/any/dir" \ CXXFLAGS="-I/any/dir" \ DSOFLAGS="-L/any/dir" \ LDFLAGS="-L/any/dir" \ ./configure

To enable support for encryption, you will need to add the --enable-ssl option:

#./configure --enable-ssl

SSL and TLS support requires the OpenSSL library, which is available at http://www.openssl.org.

If the OpenSSL headers and libraries are not installed in the standard directories, you can configure them using --with-openssl-includes and --with-openssl-libs options:

#./configure --enable-ssl \ --with-openssl-includes=/foo/bar/include \ --with-openssl-libs=/foo/bar/lib

Once the configuration is done, you can start building the software by using the following command:

#make

If you are using FreeBSD, NetBSD, or OpenBSD systems, use the following command instead:

#gmake
