Compile and link all the program in the example directory:

make

Using this command, all the executable files will be generated in the bin directory and their symbolic link will be generated in the local home directory.

Run program generated by example/FileName.cpp:

./FileName

or

./bin/FileName

Clean:

make clean

Generate Doxygen documentation:

make doxygen

bin: The output objects executables go here, for the applications, examples and tests.

build: This folder contains all object files to generate the library, and is removed on a clean.

doc: Any documents including LaTeX files and also code documents are here; generated doxygen files are in the html subdirectory.

example: The source files for all the numerical examples.

include: All project header files. All necessary third-party header files that do not exist under /usr/local/include are also placed here.

lib: Any libs that get compiled by the project (currently the libsgdg shared library), third party or any needed in development.

source: The source files to generate the library.

deps: files of dependency, automatically generated by makefile; removed on a clean.

test: The source files for unit tests.

script: scripts including python code for plot
