1. Compiling from source
1.1. URLs
o http://auricle.dyndns.org/ALE/download/ale-0.9.0.3.tar.gz
1.2. Build prerequisites
1.2.1. GCC C++ compiler
GCC version 3.2.3 with C++ support is known to build ALE successfully.
Older versions of GCC may fail to compile some versions of ALE.
1.2.2. Prerequisites for building on Windows
Successfully running the configuration script on Windows (e.g., for native
builds) may require installation of Cygwin. For more information on
Cygwin, see:
o http://www.cygwin.com/
Alternatively, this package can be cross-compiled for Windows on a
non-Windows architecture, provided that the appropriate cross-compilers
and libraries are available.
1.3. Extraction
Download the source archive file from the URL indicated in the section
'URLs', and invoke:
tar xzf ale-0.9.0.3.tar.gz
cd ale-0.9.0.3
Invoking 'ls configure' afterward should reveal an executable script
'configure'. This script is used to determine the capabilities of the
system that will run the software.
1.4. Running configure
This package uses a configuration script, 'configure', generated by the
GNU project build tools ("autotools"). For most cases, it should be
sufficient to invoke:
./configure
make
make install
In cases where the defaults are not adequate, configuration options can be
passed to the configuration script.
1.5. Configuration options
Configuration options can be passed to the 'configure' script prior to
build and installation, as:
./configure --config-option1 --config-option2 ...
make
make install
Options specific to this package are described in the following
subsections. General configuration options are described in the file
'INSTALL' included in the source package.
1.5.1. ImageMagick Support
Enabling ImageMagick support allows ALE to make use of the file-handling
capabilities of ImageMagick ( http://imagemagick.org/ ). This includes
reading and writing a variety of file formats, including, among many
others, PNG and JPEG (two formats commonly used in web publishing) as well
as common interchange formats such as PPM and TIFF. ImageMagick 6.0.6 is
known to work with this version of ALE; certain older versions of
ImageMagick may cause compile, link, or runtime errors. By default,
support is automatically detected.
--with-imagemagick=auto Auto-detect ImageMagick support [default]
--with-imagemagick=yes Enable ImageMagick support
--with-imagemagick=no Disable ImageMagick support
1.5.2. Color Data Precision
ALE's internal data structures store each color channel within a pixel as
floating-point data; similarly, arithmetic operations on color channels
are performed in floating point. The available data-type configurations
are listed below, with typical data sizes indicated in parentheses.
--with-colors=single Use C++ 'float' data type (32-bit) [default]
--with-colors=double Use C++ 'double' data type (64-bit)
1.5.3. Coordinate Data Precision
In general, coordinate transformations used by ALE produce results outside
of the set of integers; hence, coordinates are treated as floating-point
data. The two available data-type configurations are listed below, with
typical data sizes indicated in parentheses.
--with-coords=single Use C++ 'float' data type (32-bit) [default]
--with-coords=double Use C++ 'double' data type (64-bit)
1.5.4. Thread support
Threads can improve performance on multiprocessor machines. POSIX threads
are currently supported.
--enable-threads=auto Auto-detect thread support. [default]
--enable-threads=yes Enable thread support.
--enable-threads=no Disable thread support.
1.5.5. FFTW Support
This feature is required in order to use the --fl option; it also
determines the approach to calculation of discrete Fourier transforms used
by the Irani-Peleg renderer. For more information on FFTW, see
http://fftw.org/.
--with-fftw3=auto Auto-detect FFTW3. [default]
--with-fftw3=yes Use FFTW3 discrete Fourier transform.
--with-fftw3=no Use built-in discrete Fourier transform.
1.5.6. Enable --wmx
This build option is required in order to use the --wmx option. If
--enable-wmx is specified, it is expected that fork() and execlp() calls
are available.
--enable-wmx=auto Automatically detect whether to enable --wmx
--enable-wmx=yes Enable --wmx
--enable-wmx=no Do not enable --wmx
1.5.7. Getsize
This build option is required to obtain additional output from --ui=tty.
If TIOCGWINSZ is not defined in <sys/ioctl.h>, however, additional output
will not be provided even if --enable-getsize is specified at build time.
--enable-getsize=auto Check for TIOCGWINSZ at build time. [default]
--enable-getsize=yes Configure to attempt to use TIOCGWINSZ
--enable-getsize=no Do not attempt to use TIOCGWINSZ
1.5.8. Assertions
Finding bugs within ALE, or within custom modifications to ALE, can be
simplified by enabling run-time assertions. These checks enforce
conditions believed to be necessary or desirable for correct program
operation. If a condition is not satisfied, ALE will abort and display a
message indicating the failed assertion.
--enable-assertions Enable assertions. [default]
--disable-assertions Disable assertions.
1.6. Cross-compilation
For cross-compilation, it may be necessary to specify both host and build
machine types, using the configure --host and --build options. For more
information on these options, see the file 'INSTALL' in the source
package.
1.7. Further details
General operation of the configure script is described in more detail in
the file 'INSTALL' in the source package.
