- You will need certain additional libraries when you compile some of the
- units. These can be found in the directory
- `ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/libs/'.
-
- Currently, there are the following libraries:
-
- gmp
- Arithmetic for integers, rationals and real numbers with arbitrary
- size and precision. Used by the GMP unit.
-
- rx
- Regular expression matching and substitution. Used by the RegEx
- unit.
-
- ncurses
- PDCurses
- Screen handling. Used by the CRT unit. Depending on your system,
- you have the following choices:
-
- Unix: You can compile terminal applications with ncurses and
- applications that run in an X11 window with PDCurses (though
- terminal applications can, of course, also run in an xterm under
- X11). ncurses is used by default. If you want to use PDCurses
- (a.k.a. XCurses), give the option `-DX11' when compiling CRT.
-
- Dos with DJGPP and MS-Windows with mingw: Only PDCurses is
- available and will be used by default.
-
- MS-Windows with Cygwin: PDCurses and ncurses are available.
- PDCurses is used by default. If you want to use ncurses, give the
- option `-DUSE_NCURSES' when compiling CRT.
-
- Other systems: Please see the `README's and installation
- instructions of PDCurses and ncurses to find out which one(s) can
- be built on your system. See the conditionals at the end of
- crt.inc and crtc.h (and change them if necessary) on which library
- is used by default.
-
- ElectricFence
- This library is not used by any GPC unit. It is a debugging tool to
- assist you in finding memory allocation bugs. To use it, just link
- it to your program, either on the command line (`-lefence') or in
- the source code (`{$L efence}') which you might want to put into
- an `{$ifdef DEBUG}' or similar since using libefence is only
- recommended for debugging.
-
- The source code of the libraries is available in the main `libs'
- directory. Most libraries come with one or several patches which should
- be applied before compiling them.
-
- Binaries for some platforms are available in the `binary/PLATFORM'
- subdirectories. If you compile the libraries for other platforms, be
- invited to make the binaries available to us for distribution on the
- FTP site.
-
- There are also the following files:
-
- `terminfo-linux.tar.gz'
- This is a patch to enable ncurses programs to make use of the
- ability of Linux 2.2 and newer kernels to produce a block cursor
- when needed. The present patch can be installed without recompiling
- anything, just by copying some files into place. More details can
- be found in the `README' file included in this archive. The patch
- will not do any harm on older kernels. Please note that *not* only
- on Linux machines it is useful to install the patch. Installing
- them on any other machine will allow users who telnet in from a
- Linux console to profit from the block cursor capability. Besides,
- some Unix systems have installed older Linux terminfo entries or
- none at all, so it's a good thing, anyway, to give them a current
- version. The patch is included in the terminfo database of ncurses
- 5.0, so if you install ncurses 5.0 (source or binary), you don't
- need to get the patch separately. But you can install it on a
- system with an older ncurses version if you don't feel like
- upgrading ncurses altogether.
-
- `tsort-2.9i.zip'
- A little utility (extracted from util-linux-2.9i, but not Linux
- specific), needed for the configuration of the rx library. You
- need it only if you compile rx yourself (and if it's not already
- present on your system), not when using a rx binary.
