In a few new tutorials that i am gonna write I will showing out how to create a few viruses. I will be using mostly C++ Programming language to do it bcoz I am more or less familiar with it. So if you guys also want to create those stuffs you should have a basic knowledge about c++ or atleast should know how to compile a c Program.

If you want to learn C++ throughly then visit http://www.docnmail.com/learn/CCpp.htm, but anywayz here is a tutorial on “How To Compile C Programs.”

How to install Borland C++ compiler
1. Download Borland C++ compiler 5.5 (for Windows platform) from the following link.

http://www.codegear.com/downloads/free/cppbuilder

2. After you download, run freecommandlinetools.exe. The default installation path would be

C:\Borland\BCC55

How to configure Borland C++ compiler
1. After you install Borland C++ compier, create two new Text Documents

2. Open the first New Text Document.txt file and add the following two lines into it

-I”c:\Borland\Bcc55\include”

-L”c:\Borland\Bcc55\lib”

Save changes and close the file. Now rename the file from New Text Document.txt to bcc32.cfg.

3. Open the second New Text Document (2).txt file and add the following line into it

-L”c:\Borland\Bcc55\lib”

Save changes and close the file. Now rename the file from New Text Document (2).txt to ilink32.cfg.

4. Now copy the two files bcc32.cfg and ilink32.cfg, navigate to C:\Borland\BCC55\Bin and paste them.

How to compile the C source code (.C files)
1. You need to place the .C (example.c) file to be compiled in the following location

C:\Borland\BCC55\Bin

2. Now goto command prompt (Start->Run->type cmd->Enter)

3. Make the following path as the present working directory (use CD command)

C:\Borland\BCC55\Bin

4. To compile the file (example.c) use the following command

bcc32 example.c

5. Now if there exists no error in the source code you’ll get an executable file (example.exe) in the same location (C:\Borland\BCC55\Bin).

6. Now you have successfully compiled the source code into an executable file(.exe file).
