This file describes how to compile and install the IPP sample code. For more
information on the IPP sample code see the file called README.md
. Changes are
summarized in the file CHANGES.md
.
You'll need a C99-compliant C compiler plus a POSIX-compliant make program and a POSIX-compliant shell (/bin/sh). The GNU compiler tools and Bash work well and we have tested the current IPP sample code against several versions of Clang and GCC with excellent results.
The makefiles used by the project should work with most versions of make. BSD users should use GNU make (gmake) since BSD make does not support the POSIX "include" directive.
Besides these tools you'll need the following libraries:
- Avahi or mDNSResponder for mDNS/DNS-SD support
- GNU TLS, LibreSSL, or OpenSSL for encryption support
- ZLIB for compression support
- CoreGraphics (macOS), Poppler, or Xpdf PDF rasterization support (optional)
- CuraEngine for 3MF/STL slicing support (optional)
- PAM for authentication support (optional)
On a stock Debian/Ubuntu install, the following command will install all prerequisites:
sudo apt-get install build-essential autoconf avahi-daemon avahi-utils \
cura-engine libavahi-client-dev libnss-mdns libpam-dev libssl-dev \
zlib1g-dev
The IPP sample code uses GNU autoconf, so you should find the usual configure
script in the main source directory. To configure the code for your system,
type:
./configure
The default installation will put the software in the /usr/local
directory on
your system. Use the --prefix
option to install the software in another
location:
./configure --prefix=/some/directory
To see a complete list of configuration options, use the --help
option:
./configure --help
If any of the dependent libraries are not installed in a system default location
(typically /usr/include
and /usr/lib
) you'll need to set the CFLAGS,
CPPFLAGS, CXXFLAGS, DSOFLAGS, and LDFLAGS environment variables prior to running
configure:
CFLAGS="-I/some/directory" \
CPPFLAGS="-I/some/directory" \
CXXFLAGS="-I/some/directory" \
DSOFLAGS="-L/some/directory" \
LDFLAGS="-L/some/directory" \
./configure ...
Once you have configured things, just type:
make ENTER
to build the software.
Once you have built the software you need to install it. The install
target
provides a quick way to install the software on your local system:
make install ENTER
Use the BUILDROOT variable to install to an alternate root directory:
make BUILDROOT=/some/other/root/directory install ENTER
Pass the --enable-debug
option to the configure script to enable debug logging
support. The following environment variables are used to enable and control
debug logging at run-time:
CUPS_DEBUG_FILTER
: Specifies a POSIX regular expression to control which messages are logged.CUPS_DEBUG_LEVEL
: Specifies a number from 0 to 9 to control the verbosity of the logging. The default level is 1.CUPS_DEBUG_LOG
: Specifies a log file to use. Specify the name "-" to send the messages to stderr. Prefix a filename with "+" to append to an existing file. You can include a single "%d" in the filename to embed the current process ID.
