3 What is this quick start guide about? 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.3

4  In this quick start guide, you will first of all install BASIS in your system.  Then, you will use so-called project tool of BASIS to create a new project.  After you created a new and empty project, you will add some example source files and edit the build configuration files to build the executable and library files.  Finally, you will build and test the example project.  For a more detailed explanation of each step, have a look at the corresponding BASIS Tutorial.BASIS Tutorial 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania.

5  To follow the steps in this quick start guide, you need to have a Unix-like operating system. Specifically, we focus on Linux, but it has also been tested on Mac OS X.  Note that BASIS can also be installed and used on Windows. The tools for creating a new project and for automated software tests are, however, only available for Unix.  At the moment, there is no separate quick start guide available for Windows users.  Alternatively, you can install CygWin.CygWin  This would also allow you to use the BASIS tools which are not available for native Windows. 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania.

6 How do I get BASIS installed on my system? 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.6

7  Download the source code of BASIS 0.1:  mkdir -p ~/local/src  cd ~/local/src  svn export https://sbia-svn.uphs.upenn.edu/projects/BASIS/tags/basis basis-0.1 https://sbia-svn.uphs.upenn.edu/projects/BASIS/tags/basis /21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.7

8  Before you can build BASIS, you need to configure it using CMake or greater.  Configure the build system using CMake:  mkdir basis-0.1-build  cd basis-0.1-build  ccmake../basis-0.1  Hit ‘c’ to configure the project.  Change INSTALL_PREFIX to ~/local.  Disable any of the BUILD_*_UTILITIES options depending on whether you have Python or Perl installed on your system and intend to use these languages.  Hit ‘g’ to generate the Makefiles. 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.8

9  CMake has generated Makefiles for GNU Make.  Therefore, the build is triggered by the make command:  make 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.9

10  To install BASIS, we “build” the install target:  make install  As a result, CMake copies the built files into the installation tree as specified by the INSTALL_PREFIX variable.  Additionally, BASIS may create some symbolic links on Unix systems if the INSTALL_LINKS option was set to ON during the configuration of BASIS. 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.10

11  Se the following environment variables:  setenv PATH " ~/local/bin:${PATH} "  setenv BASIS_EXAMPLE_DIR " ~/local/share/basis/example "  setenv HELLOBASIS_RSC_DIR " ${BASIS_EXAMPLE_DIR}/hellobasis "  Using BASH:  export PATH= " ~/local/bin:${PATH} "  export BASIS_EXAMPLE_DIR= " ~/local/share/basis/example "  export HELLOBASIS_RSC_DIR= " ${BASIS_EXAMPLE_DIR}/hellobasis " 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania.

12 How do I create my own BASIS-conform project? 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.12

13  Create a new and empty project as follows:  basisproject --name HelloBasis --description " This is a BASIS project. " --root ~/local/src/hellobasis  The next command demonstrates that you can modify a previously created project using again the project tool:  basisproject --root ~/local/src/hellobasis --noexample --config-settings  Here we removed the example/ subdirectory and added some configuration file used by BASIS. These options could also have been given to the initial command above instead. 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.13

15 Fine, so how do I build and install this BASIS project? 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.15

16  The build and installation of this BASIS project is identical to the build and installation of BASIS itself.  In fact, all CMake-based projects are build this way. Therefore, the file INSTALL-basis.txt which is part of BASIS summarizes these steps. INSTALL-basis.txt  Build and install the (yet empty) project:  mkdir ~/local/src/hellobasis-build  cd ~/local/src/hellobasis-build  cmake -D INSTALL_PREFIX=~/local../hellobasis  make 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania.

17 How do I get my executables build? 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.17

18  Copy the source file from the example to src/ :  cd ~/local/src/hellobasis  cp ${HELLOBASIS_RSC_DIR}/helloc++.cxx src/  Add the following line to src/CMakeLists.txt under the section “executable target(s)”:  basis_add_executable (helloc++.cxx)  Note: Alternatively, you can use the implementation of this example executable in Python, Perl, BASH or MATLAB.  In case of MATLAB, add also a dependency to MATLAB:  basisproject --root ~/local/src/hellobasis --use MATLAB 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.18

19  The name of the output file is given by the OUTPUT_NAME property.  The name of the symbolic link is given by the SYMLINK_NAME property.  To change these properties, add the following lines to the src/CMakeLists.txt (after basis_add_executable() ):  basis_set_target_properties (  helloc++  PROPERTIES  OUTPUT_NAME " hellobasis "  SYMLINK_NAME " helloworld "  )  Note: If you used another example, you need to replace helloc++ by the name of the source file you used excluding the extension. 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.19

20 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.20  To conclude, your src/CMakeLists.txt file should now contain CMake code similar to the following snippet:  basis_add_executable (helloc++.cxx)  basis_set_target_properties (  helloc++  PROPERTIES  OUTPUT_NAME " hellobasis "  SYMLINK_NAME " helloworld "  )

21 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.21  Now build the executable and test it:  cd ~/local/src/hellobasis-build  make  bin/hellobasis  How is it going?  Note: As you configured the build system before using CMake, we only need to run GNU Make. CMake will recognize the change of src/CMakeLists.txt and reconfigure the build system automatically.  Install the executable and test it:  make install  helloworld  How is it going?  Note: The symbolic link named helloworld is in ~/local/bin/ which is already in our search path for executables (PATH).

22 How do I add libraries/modules to my project? 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.22

23 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.23  Copy the files from the example to src/ :  cd ~/local/src/hellobasis  cp ${HELLOBASIS_RSC_DIR}/foo.* src/  Add the following line to src/CMakeLists.txt (section “library target(s)”):  basis_add_library (foo.cxx)  Note: This is a library without public interface.

24 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.24  Create the subdirectory tree for the public header files:  cd ~/local/src/hellobasis  basisproject --root. --include  Copy the files from the example:  cp ${HELLOBASIS_RSC_DIR}/bar.cxx src/  cp ${HELLOBASIS_RSC_DIR}/bar.h include/sbia/hellobasis/  Add the following line to src/CMakeLists.txt (section “library target(s)”):  basis_add_library (bar.cxx)  Note: This is a library with public interface as declared in bar.h.

25 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.25  Another kind of libraries are modules written in a scripting language such as Perl.  Copy the module file to src/ :  cd ~/local/src/hellobasis  cp ${HELLOBASIS_RSC_DIR}/FooBar.pm.in src/  Add the following line to src/CMakeLists.txt (section “library target(s)” ):  basis_add_library (FooBar.pm)

26 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.26  Note that some of these files have a.in file name suffix.  This suffix can be omitted in the basis_add_library() statement. It has however an impact on how this function treats this file.  The.in suffix indicates that the file is not usable as is, but contains patterns such as which BASIS should replace during the build of the module.  The substitution of these patterns is what we refer to as “building” script files.

27 10/21/2011Getting Started Copyright (c) 2011 University of Pennsylvania. All rights reserved.27  Now build the libraries:  cd ~/local/src/hellobasis-build  make  And install them:  make install
