Version 5.0 The LEDA User Manual

Preparations
Unpacking the LEDA distribution file LEDA-complete---.tar.gz will
create the LEDA root directory ”LEDA-complete---”. You might want
to rename it or move it to some different place. Let denote the final complete
path name of the LEDA root directory.
To install and use the Unix object code of LEDA you have to modify your environment
as follows:
• Set the environment variable LEDAROOT to the LEDA root directory:
csh/tcsh:
sh/bash:
setenv LEDAROOT
LEDAROOT=
export LEDAROOT
• Include $LEDAROOT/Manual/cmd into your command search path (environment variable
path (csh) or PATH (sh)) and call rehash (if required by your system).
• Shared Libraries: (for solaris, linux, irix, osf1)
If you planning to use shared libraries include $LEDAROOT into the LD LIBRARY PATH
search path. Then go to $LEDARROOT and type make shared. This will construct
the shared libraries from the static libraries.
• xlman and demos: Go to $LEDAROOT and type make xlman to compile and link
LEDA’s interactive manual reader xlman. Now you can start xlman for reading and
printing manual pages, starting demo programs and browsing more release notes.
Compiling and Linking Application Programs
1. Use the -I compiler flag to tell the compiler where to find the LEDA header files.
CC (g++) -I$LEDAROOT/incl -c file.c
2. Use the -L compiler flag to tell the compiler where to find the libraries (libL.a/so,
libG.a/so, ...)
CC (g++) -L$LEDAROOT file.o
: -lL -lm (basic data types)
-lG -lL -lm
(graph data types)
-lP -lG -lL -lm
(planar geometry)
-lD3 -lP -lG -lL -lm
