Version 5.0 The LEDA User Manual

• 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 to indicate the root directory of your LEDA installation,
e.g., c:\LEDA-4.4\.
Programs using basic data types:
bcc32 -DLEDA_DLL -P -I\incl -L prog.c leda.lib
Programs using GeoWin:
bcc32 -DLEDA_DLL -P -I\incl -L prog.c\
libGeoW.lib leda.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
\test and \demo. Goto and type make test or make demo to compile
and link all test or demo programs, respectively.
A.15 Namespaces and Interaction with other Libraries
If users want to use other software packages like STL together with LEDA in one project
avoiding naming conflicts is an issue.
LEDA defines all names (types, functions, constants, ...) in the namespace leda. This
makes the former macro–based prefixing scheme obsolete. Note, however, that the prefixed
names “leda ...” still can be used for backward compatibility. Application programs have
to use namespace “leda” globally (by saying "using namespace leda;") or must prefix
every LEDA symbol with "leda::".
The second issue of interaction concerns the data type bool which is part of the new C++
standard. However not all compilers currently support a bool type. LEDA offers bool
either compiler provided or defined within LEDA if the compiler lacks the support. Some
STL packages follow a similar scheme. To solve the existance conflict of two different bool
type definitions we suggest to use LEDA’s bool as STL is a pure template library only
provided by header files and its defined bool type can be easily replaced.
