Static Libraries for Borland C++

This section describes the installation and usage of static libraries of LEDA with Borland C++ (bcc32 version 5.5.1 and 5.6).

Remark: This section describes the situation in a GUI package of LEDA. If you have the geometry, graph, or basic package only the corresponding libraries are provided.

Preparations

To install LEDA you only need to execute the LEDA distribution file LEDA-<ver>-<package>-win32-<compiler>.exe. During setup you can choose the name of the LEDA root directory and the parts of LEDA you want to install.

Then you have to set the environment variable LEDAROOT as follows:

1. Windows NT/2000/XP: On these platforms LEDARROOT is set automatically to the directory where you installed LEDA by the setup program.

2. Windows 95/98:
   1. Add the line set LEDAROOT=<LEDA> to the file "autoexec.bat" where <LEDA> is the root directory of your LEDA installation, e.g., D: \LEDA-4.4 \
   2. Restart Windows 95/98 for the change to take effect.

Files and Directories

To compile and link your programs with LEDA, the LEDA main directory should contain at least the following files and subdirectories:

Readme.txt	Readme File
Install \win32_bcc_lib.txt	txt-version of this section
incl \	the LEDA include directory
man_html \	HTML version of the LEDA user manual

and the following library set

• libl.lib, libg.lib, libp.lib, libw.lib, libgeow.lib, libd3.lib

Compiling and Linking Application Programs in a DOS-Box

(a) Setting the Environment Variables for Borland C++:

• Make sure that that the directory containing bcc32.exe is contained in your path. bcc32.exe is located in the \bin subdirectory of your compiler (, e.g., c: \programs \borland \cbuilder6 \bin)

• Make sure that there is a file bcc32.cfg in the \bin subdirectory of your compiler which sets the compiler options for the Include and Lib paths (-I and -L switches of compiler). On the authors machine the following lines had to be added to bcc32.cfg:
  -I"c: \programs \Borland \cbuilder6 \include"
  -L"c: \programs \Borland \cbuilder6 \lib"

• Make sure that there is a file ilink32.cfg in the \bin subdirectory of your compiler which sets the linker option for the Lib path. The author had to add the following line to ilink32.cfg :
  -L"c: \programs \Borland \cbuilder6 \lib"

(b) Compiling and Linking Application Programs:

Now you can use the LEDA libraries as follows to compile and link your application programs.

We use <LEDA> to indicate the root directory of your LEDA installation, e.g., c: \LEDA-4.4 \.

Programs using basic data types:

bcc32 -P -I<LEDA>\incl -L<LEDA> prog.c libl.lib

Programs using graph data types:

bcc32 -P -I<LEDA>\incl -L<LEDA> prog.c libg.lib libl.lib

Programs using geometric data types:

bcc32 -P -I<LEDA>\incl -L<LEDA prog.c libp.lib libg.lib libl.lib

Programs using three-dimensional data types:

bcc32 -P -I<LEDA>\incl -L<LEDA> prog.c libd3.lib libp.lib libg.lib\
libl.lib

Programs using graphics data types:

bcc32 -P -I<LEDA>\incl -L<LEDA> prog.c libw.lib libp.lib libg.lib\
libl.lib wsock32.lib user32.lib gdi32.lib comdlg32.lib shell32.lib\
advapi32.lib

Programs using GeoWin:

bcc32 -P -I<LEDA>\incl -L<LEDA> prog.c libgeow.lib libd3.lib\
libw.lib libp.lib libg.lib libl.lib wsock32.lib\
user32.lib gdi32.lib comdlg32.lib shell32.lib advapi32.lib

Remark: The option -P is necessary if the C++ source code files have extension .c. If your files have extension .cpp this option is not necessary.

Example programs and demos

The source code of all example and demo programs can be found in the directory <LEDA> \test and <LEDA> \demo. Goto <LEDA> and type make_test or make_demo to compile and link all test or demo programs, respectively.
