PA1 code base contains five directories, Makefile and other supported files required to complete the PA1 and described as follows:
1. The include directory contains a header file crypter.h for the crypter library. This header file provides function and data types declaration for the crypter library, and being used for the test-cases. Don't modify this header file.
2. The src directory contains skeleton code for the library you are going to implement for CryptoCard. This directory contains one file crypter.c. You need to complete the definition of the function provided in the crypter.c. After a successful build of the library, a shared library file libcrypter.so is being generated in the lib directory. Initially there is no such directory with name lib is present in the code. This directory will automatically be created by the Makefile on successful build of any test-cases.
3. The test-cases directory contains the test-cases that uses the library you are going to build for the CryptoCard.
4. The report directory contains a blank README file. Before submitting the assignment, populate it with necessary information like references used, help taken from others etc. for completing the PA. Apart from the README file, you need to submit a report in PDF that you can place within the same directory.
5. The drivers directory is placeholder where you should put your drivers code along with its associated makefile. Makefile should generate driver module with name cryptocard_mod.ko in the drivers directory only.
6. The CS730_2021_22_PA.pdf file describes the Programming Assignment (PA).
Use make command to compile the assignment. After successful compilation, all the binaries for test-cases are generated in the root directory of the PA code base. Apart from the binary file, additionally two directory are generated namely, lib and obj. The directory lib holds the object code and shared library libcrypter.so for CryptoCard while obj populated with the object code of the test-cases.
1. Compile code for all the test-cases: To compile for all the test-cases, use the make command from the root directory of the PA code base.
make
2. Compile Individual test-case code: Individual test-case code can be compiled using the make command followed by the test-case name in lower case. For example, if you want to build the code base for test-case 1, the syntax is as follows:
make test1
Similarly, other test-cases can be compiled individually.
3. Clean the build:
make clean
After the compilation of an individual test case code, the binary files are placed in the root directory of the PA code base.
Note: Add following line in your .bashrc file in your home directory(Eg: /home/cs730/.bashrc). Otherwise you will get error when you try to execute the test case binary file. export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:
Eg: export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/cs730/Desktop/CS730-PA-library-master/lib/
To prepare the submission tar file, make utility can be utilized for the same. But before preparing it, first, prepare your report in PDF and place it inside the report directory. Apart from the report file, you need to update the README file present in the report directory as per the requirement. The syntax for creating the submission tar file is as follows:
make prepare-submit RNO=Roll_Number
