I have found a program and tried using 'DEV C++' but it only reported an error report. I later then discovered that is was because 'DEV C++' used C++ when the code was designed for just plane C. I have searched the web and this forum but only found two relevant threads from this forum (as shown below):

http://www.daniweb.com/forums/showth...ght=c+compiler
However, this still does not answer my question. And that is where to find a FREE or cheap compiler which compiles only 'C' code and not C++.

DEV C++ compiles C or C++ just fine. What is the reported error ?

The links you posted give me a 404 page not found error.

Below is the error:

and it says [Build Error] multiple target patterns. And for the links above (which I have just checked, the way to get to the is be searching this forum for 'c compiler' (in threads) and they are in the first 3 pages.

One of the things that Dev C++ gets mixed up with is when you use a code like:
#include "../encoder.h"
It gets mixed up with the .h

Ok I'm not too sure. But this might have something to do with dependancy. Is there more than 1 makefile in your download?

One of Dev-C++ shortfalls is it can't compile multiple projects all at once. You have to compile them one at a time, and you have to know manually in which order to build them.

What!? just save the file as something.c and hit the compile button. Job done.

The thing is, the source code did not come with a make file and I think dev C++ is having trouble making it. Below is the link to the source code (and I hope this link works).

So now I am trying to contact technical support for this source code to see what compiler they recommend.

you can use Pelles C compiler, it's very nice compiler for c and free.

Pelles C site:
http://www.christian-heffner.de/

read the INSTALL file and it will tell you that they used VC++ 6 and NASM assembler.

Well if you want a simple command line compiler then you can go for DJGPP It'll work good too.
