Version 5.0 The LEDA User Manual

Compiling and Linking Application Programs in a DOS-Box
(a) Setting the Environment Variables for Visual C++:
The compiler CL.EXE and the linker LINK.EXE require that the environment variables
PATH, INCLUDE, and LIB have been set properly.
When Visual C++ was installed, setup created a batch file, VSVARS32.BAT, containing
commands to modify PATH, LIB, and INCLUDE. Run VSVARS32.BAT at the command
prompt before you compile your application program. VSVARS32.BAT is located in
the \bin subdirectory of your compiler installation, e.g., c:\programs\microsoft
visual studio .NET\Vc7\bin.
To compile programs together with LEDA, the environment variables PATH, LIB,
and INCLUDE must additionally contain the corresponding LEDA directories.
(b) Setting Environment Variables for LEDA:
(i) Windows NT/2000/XP:
1. In the ”Start” menu, point to ”Settings”, then click ”Control Panel”.
2. In the ”Control Panel”, double click ”System”.
3. In the System Properties dialog box, click the Environment tab (for NT),
respectively the Extended tab and then on ”Environment Variables” (for
2000/XP).
If a user variable PATH, LIB, or INCLUDE already exists, extend the current
value as follows:
• extend PATH by
• extend INCLUDE by \incl
• extend LIB by
Otherwise add new a user variable PATH, INCLUDE, or LIB with value
, respectively \incl.
(ii) Windows 95/98:
1. Change the file autoexec.bat as follows:
If a variable PATH, INCLUDE, or LIB is already set, append the appropriate
LEDA directory , respectively \incl.
Otherwise add a corresponding line to autoexec.bat:
set PATH=
set INCLUDE=\incl
set LIB=
2. Restart Windows 95/98 for the change to take effect.
After these procedures, it suffices to call VSVARS32.BAT at the command prompt.
In both cases the LEDA paths are automatically appended to the compiler paths.
(c) Compiling and Linking Application Programs:
After setting the environment variables, you can use the LEDA libraries as follows
to compile and link programs.
