<H3> Use of APRON PPL </H3>
<!--docid::SEC66::-->
<P>
To use APRON PPL in C, you need of course to install PPL, <EM>after
having patched it</EM> following the recommendations of the <TT>`README'</TT>
file. You need also to add
<TABLE><tr><td> </td><td class=example><pre>#include "apron_ppl.h"
</pre></td></tr></table>in your source file(s) and add <SAMP>`-I$(APRON_PREFIX)/include'</SAMP> in the
command line in your Makefile.
</P><P>
You should also link your object files with the APRON PPL library to
produce an executable, <EM>using</EM> <SAMP>`g++'</SAMP> (instead of <SAMP>`gcc'</SAMP>,
because <TT>`libppl.a'</TT> is a C++ library), and adding something like
<SAMP>`-L$(APRON_PREFIX)/lib -lapron_ppl -L$(PPL_PREFIX)/lib -lppl
-L$(GMP_PREFIX)/lib -lgmpxx'</SAMP> in the command line in your Makefile
(followed by the standard <SAMP>`-lapron -litvmpq -litvdbl
-L$(MPFR_PREFIX)/lib -lmpfr -L$(GMP_PREFIX)/lib -lgmp'</SAMP>). The
<TT>`libgmpxx.a'</TT> library is the C++ wrapper on top of the GMP
library. Ensure that your GMP installation contains it, as it is not
always installed by default.
</P><P>
All scalars of type <CODE>double</CODE> are converted to scalars of type
<CODE>mpq_t</CODE> inside APRON PPL, as APRON PPL works internally with exact
rational arithmetics. So when possible it is better for the user (in
term of efficiency) to convert already <CODE>double</CODE> scalars to
<CODE>mpq_t</CODE> scalars.
</P><P>
The wrapper library is available in debug mode
(<SAMP>`libapron_ppl_debug.a'</SAMP>).
