You can download the source code of the current GNU Pascal release
from
http://www.gnu-pascal.de/current/and binaries for some platforms from
http://www.gnu-pascal.de/binary/
The binary archive files are named
gpc-version.platform.extension
- for example
gpc-2.1.alpha-unknown-linux-gnu.tar.gz
for GPC version 2.1 on an
Alpha workstation running the Linux kernel with GNU C Library, or
gpc-20000616.i586-pc-djgppv201.zip
for GPC version 20000616 on an
i586 PC running DOS with DJGPP version 2.01.
After you have downloaded the correct archive file for your platform, please read the installation notes on how to install such a binary distribution.
If you are running Dos or MS Windows, you will need additional tools - see "What else to download and where" below.
GNU Pascal is subject to steady development. Alpha and beta
snapshots (source only, use at your own risk) can be found at:
http://www.gnu-pascal.de/alpha/ http://www.gnu-pascal.de/beta/
When you are using GNU Pascal on a DOS system, you will need either the DJGPP or the EMX development environment (see below). On an OS/2 system, you will need EMX. On an MS Windows 95/98/NT system you will need either the CygWin or the mingw32 environment.
GNU Pascal uses the compiler back-end from the GNU Compiler
Collection, GNU CC or GCC. If you want to compile GPC, you will need
the source of GCC as well as the source of GPC itself. From the same
place as GPC, please download GCC 2.8.1, 2.95.x or 3.2.1
. (It is
also available from any GNU mirror; see
http://www.gnu.org/software/gcc/.)
For some of GPC's units, you will need some standard libraries. In particular:
Unit | Platform | Library
|
CRT | Unix/terminal | ncurses >= 5.0 (1), (2)
|
CRT | Unix/X11 | PDCurses (2)
|
CRT | Dos, MS-Windows | PDCurses (3)
|
GMP | any | gmp
|
RegEx | any | rx
|
(debugging) | Unix, MS-Windows | ElectricFence (4)
|
Notes:
(1) ncurses version 5.0 or newer is strongly recommended because older versions contain a bug that severely affects CRT programs.
(2) You can install both ncurses and PDCurses on a Unix system, and choose at compile time whether to generate a terminal or X11 version of your program.
(3) ncurses also runs under MS-Windows with CygWin (not mingw32, however), but doesn't appear to behave much differently from PDCurses on that platform.
(4) ElectricFence is not used by any unit, but can be used for debugging memory allocation bugs by simply linking it (see the accompanying documentation).
You can find those libraries on many places on the Net. Also, many
GNU/Linux distributions, DJGPP mirrors and other OS distributions
already contain some of the libraries. In any case, you can find the
sources of the libraries (sometimes together with patches that you
should apply before building if you choose to build from the
sources) and binaries for some platforms in
http://www.gnu-pascal.de/libs/
For more information and descriptions of these libraries, see Libraries.
gnu/djgpp
subdirectory; for addresses
look into the DJGPP FAQ.
To use GNU Pascal you need at least
v2/djdev201.zip
, and
binutils
(assembler, etc.), v2gnu/bnu270b.zip
.
We also recommend you to get:
make
utility, v2gnu/mak375b.zip
v2gnu/gdb416b.zip
v2faq/faq211b.zip
v2app/rhide.zip
, another integrated development
environment, or
EMX is an environment for creating 32-bit applications for DOS and OS/2.
It is available from:
http://www.leo.org/pub/comp/os/os2/leo/gnu/emx+gcc/index.html
To develop EMX programs with GNU Pascal you need at least
emxrt.zip
,
emxdev*.zip
, and
gnudev*.zip
.
If your DOS box has DPMI (it does if you are using MS Windows or OS/2)
you will also need RSX, available from the same sites as EMX in the
subdirectory rsxnt
.
The GNU development tools contain the GNU C compiler which is in fact not needed to use GNU Pascal. However, the C library is needed.
CygWin is an environment which implements a POSIX layer under MS
Windows, giving it large parts of the functionality of Unix. CygWin
contains development tools such as an assembler, a linker,
etc. GPC needs for operation. More information about CygWin can be
found at
http://cygwin.com
The Minimalists' GNU Win32 environment, mingw32, allows a large
number of Unix programs - including GPC and GCC - to run under MS
Windows 95/98/NT using native MS libraries. mingw32 ressources can
be found at
http://www.mingw.org
