Graph Diameter Estimator on MPI
From the root directory of the project
mkdir build
cd build
cmake ..
make
In the build directory
make
make test
In the build directory
make doc
The generated documentation will be available in doc/html
The documentation of the script scripts/pair2adjacency.py is available
here.
The clang static analizer can be used to detect potential bugs
in the code. First install the latest version of the clang compiler.
Then, from the project root directory
mkdir check
cd check
scan-build cmake ..
scan-build make
The static analyzer will output something similar to this
scan-build: Using '/usr/bin/clang' for static analysis

scan-build: Run 'scan-view /tmp/scan-build-2013-05-22-1' to examine bug reports.
To view the report generated by the tool, run the command suggested in the output, in this case
scan-view /tmp/scan-build-2013-05-22-1
To generate project files for the Eclipse IDE, run the following from the project root directory
cd ..
mkdir gdem_eclipse
cd gdem_eclipse
cmake -G "Eclipse CDT4 - Unix Makefiles" ../gdem
Then you can import the project into Eclipse from the directory
gdem_eclipse. Please note that due to the way Eclipse works (at least
Eclipse Indigo) the Eclipse directory must be a sibiling of the project's
root directory in order to perform out of source builds (that is highly desirable).
