<title>Using libjclass in your application</title>
<para>
The easiest way to compile an application with libjclass is by using the
pkg-config utility. The following shell session shows how to compile
a hello program with pkg-config.
<example>
<title>Compile hello.c that uses libjclass</title>
<computeroutput>
cc `pkg-config --cflags --libs jclass` hello.c -o hello
</computeroutput>
</example>
</para>
<para>
If you don"t have pkg-config you can still use libjclass, but
you will need a little more effort.
<example>
<title>Compile hello.c that uses libjclass on MinGW</title>
jclassinfo is installed in jdir.
<computeroutput>
gcc -Ijdir/include -Ljdir/lib -lc -lm -lz -ljclass -o hello.exe hello.c
</computeroutput>
</example>
</para>
<para>
Here"s the source code for a sample hello.c.
</para>
<para>
It loads the HelloWorld class, gets its fully qualified name and prints it.
