This is to read a file in AT&T graphviz format into a BGL graph. The
|
|
type of the BGL graph has to be either <tt>GraphvizDigraph</tt> or
|
|
<tt>GraphvizGraph</tt>. You need build the <tt>libbglviz.a</tt> library
|
|
and link the library into your program properly.
|
|
|
|
<h3>How to build library <tt>libbglviz.a</tt></h3>
|
|
set <tt>CXX</tt> to be your compiler command. For example(in tcsh shell):
|
|
<pre>
|
|
setenv CXX "g++ -ftemplate-depth-100 -Wno-long-long"
|
|
</pre>
|
|
or (in bash shell):
|
|
<pre>
|
|
export CXX="g++ -ftemplate-depth-100 -Wno-long-long"
|
|
</pre>
|
|
|
|
Assume your boost top directory is <tt>boost_X_XX_X</tt>, then
|
|
<pre>
|
|
cd boost_X_XX_X/libs/graph/src
|
|
$CXX -I../../../ -I. -c *.cpp
|
|
ar -rc libbglviz.a *.o
|
|
ranlib libbglviz.a
|
|
</pre>
|
|
|
|
Note that for some compilers, the process to build libraries is
|
|
slightly different. You should follow your compiler manual. For example,
|
|
to use Kuck and Associates C++ compiler to build the library:
|
|
<pre>
|
|
KCC +K0 --one_instantiation_per_object -I../../../ -I. -c *.cpp
|
|
KCC +K0 --one_instantiation_per_object -o libbglviz.a *.o
|
|
</pre>
|

|
Example</A>
|
|
</H3>
|
|
|
|
<P>
|
|
The example in <a
|
|
href="../example/graphviz.cpp"><TT>example/graphviz.cpp</TT></a>
|
|
demonstrates using the BGL read graphviz facilities.
