			You can use exactly the same approach for C programs. In the sample SConstruct file, just change <tt>FORTRANFLAGS</tt> to <tt>CFLAGS</tt> and change the name of the source code file accordingly.

For both FORTRAN and C programs, the trick is to compile the program using the compiler flag <tt>-..." New page Creating a call graph for C or FORTRAN program is pretty simple using GCC. For both FORTRAN and C programs, the trick is to compile the program using the compiler flag <tt>-fdump-rtl-expand</tt> (see [https://gcc.gnu.org/onlinedocs/gcc/Debugging-Options.html documentation]). Once the program is compiled, a file with a name like <tt>solergya.f.144f.expand</tt> will be created. That file can be easily processed using the Perl-based utility [http://www.gson.org/egypt/ egypt]. Download egypt 1.10 from [http://www.gson.org/egypt/download/egypt-1.10.tar.gz here] or use our local copy, [[File:Egypt-1.10.tar.gz|egypt-1.10.tar.gz]], and to install it use <source lang=sh> tar zxvf egypt-1.10.tar.gz cd egypt-1.10 perl Makefile.PL make sudo make install </source> For example, to generate a call graph for the FORTRAN 77 program [http://energy.sandia.gov/?page_id=6530#tab1 SOLERGY], the following [http://www.scons.org SConstruct] file will build the program and generate the RTL (*.expand) file: <source lang=py> env = Environment() env.Append(FORTRANFLAGS=["-fdump-rtl-expand"]) env.Program("solergy","solergya.f") </source> Then, use egypt to convert the RTL file into a nice [http://www.graphviz.org GraphViz] diagram: <source lang=sh> egypt solergya.f.144r.expand | dot -Tpng > callgraph.png </source> The result is a nice callgraph like so: [[Image:Solergy-callgraph.png|thumb|none|600px|Callgraph for the SOLERGY program, written in FORTRAN 77]] [[Category:Miscellany]]
