How to Compile C Programs

Submitted by Srikanth on Saturday, 18 July 200929 Comments

In many of my previous posts especially in the VIRUS CREATION section, I have used C as the programming language. If you’re new to C programming and find it difficult to compile the C source codes then this post is for you. Here is a step-by-step procedure to install Borland C++ compiler 5.5 and 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).

NOTE: The above tutorial assumes that you’ve installed the compiler onto the C: drive (by default).

What’s the .c file? I get lost at the part where it tells us to move the .c file to C:\Borland\BCC55\Bin

@ a.j

Yes you can compile.. but it’ll be 16-bit… You need to compile it using a 32-bit to change it’s icon…

Hi Srikanth,
I get to the point where you enter the command promt command to compile the file. Whenever I enter “bcc32 example.c” It says that there were 18 errors in compile. And thanks for putting, so much awesome stuff up on the site.
