PGOPHER is mainly written in Pascal, using the object oriented extensions originally available from the Borland Pascal compiler and now also available in the Free Pascal compiler (not GNU Pascal). The program is distributed as a zip file. Unpack this in a directory on its own, which will create several sub-directories.
The current version is compiled with Embarcadero (originally
Borland, then Codegear) Delphi 2007 (32 bit version) and XE8 (64
bit version), though it should compile with any recent version
(2006 or later), possibly with minor modifications. The mkpgopher.bat file in
directory will compile it from the command line. Alternatively
install the utils/PutilsU.dpk
packages into the IDE (utils/Putils.dpk
for Delphi 2007 or earlier),
after which the pgopher/Pgopher.dpr
project can be loaded and compiled in the IDE. Note that various
open source graphics libraries are required for a complete
build; these are included in the GraphicEx directory.
The files with "orig" in the name are the files as distributed
with the library.
Compilation using the open source Free Pascal
(http://www.freepascal.org) and Lazarus
(http://www.lazarus.freepascal.org) packages is also possible
under Windows. Installing the current Lazarus snapshot
gives a good starting point though the development version may be
required for correct operation, particularly for Lazarus. There is
a helpful wiki page on the Lazarus site at http://wiki.lazarus.freepascal.org/index.php/Installing_Lazarus
on installing both the compiler and Lazarus. Once the Lazarus IDE
and the PGOPHER source
are installed, the instructions are as for Linux below.
or, for the command line version:lazbuild pgopher.lpi
If you don't have a recent Lazarus install, then try the makesvn script which will download and compile the current development version of the compiler and IDE, and then set up the IDE to compile PGOPHER, and use it to compile PGOPHER. It requires a bootstrap version of the compiler to start with, and the pgopher_source zip file, both in your home directory. The simplest way of obtaining this bootstrap compiler is probably to install the version of Lazarus using your distribution's package system, copy the core compiler (ppc386 or ppcx64) to your home directory and then uninstall Lazarus (to avoid confusion between versions). Alternatively, extract the file from a download for your system from http://www.freepascal.org. Given this, run the makesvn script.lazbuild pgo.lpi
Modifications and subsequent compilations can be made through
the Lazarus IDE; use startlazarus to launch it. On
first starting it you may receive a message about upgrading
configurations on starting the IDE - just accept the upgrade.
You may also see a message about configuration, which again can
be accepted. On opening the PGOPHER project or an
individual form, you may see the message "Unable to find the
component class "TSettingsForm"" - select "Ignore, use TForm as
Compilation on the Mac is similar to the process on Linux. See the "Installing Free Pascal under Mac OS X" section in the Lazarus wiki page at:
for more details. Compiling PGOPHER is then as for Linux.
PGOPHER uses slightly modified versions of selected parts of the LAPACK library to diagonalize matrices. Precompiled versions of these (using g77 or gfortran) are included with the source distribution, as these do not normally need to be recompiled. For systems other than Microsoft Windows this can normally be accomplished using the command:
make -f GNUmakefile
