What is cross compailer ?

[thannara123]

Googled ..not get the Logic .
any body help me with some example ?

 

[Venkadesh_M]

what i believe is cross compiler is a compiler which is using a already existing good compilers output to out in our destined controller's instruction format...

I also awaiting for some examples in this topic..

I too googled it, but didn't get an Idea. Are you sure it is compailer and not compiler..?

If so, I would surely like to know.

I didnt seen the 'a'.... I think that is a misatke ..

this image explains a lot

A cross compiler is simply a compiler which runs on one type of platform, e.g., Windows, Linux, MAC OS X, etc, which compilers code for another platform, e.g., PIC, AVR, ARM, etc.

Therefore, most embedded compilers are in fact cross compilers, e.g., Hi-Tech, KEIL, ARM-GCC, MikroC, etc.

The term platform in this case can refer to both a specific architecture, e.g., x86, ARM Cortex-M3, PIC16F, ATmega, etc, or an OS/RTOS.

In other words, a Windows PC system can use a cross compiler to compile code for a Linux PC system, while both may utilize an x86 based processor, in this case a cross compiler is required due to the different OSs.

I got it.. compiler is always compiles to execute in the same processor.. but a cross compiler compiles for the code to work in different processor...

 

[errakeshpillai]

Compiler has two types:
1) Native compiler: Works on some processor and compiles code to generate executable which runs on the same processor. (eg: Turbo C)
2) Cross compiler: Works on some processor and compiles code to generate executable which runs on the some other processor. (eg: keil)

There are a few pages on the internet specifying compailer, but I guess it is a typo mistake.

 

[mathespbe]

A compiler that runs on a processor and generate the executable image(hex,elf,obj,etc) of a code(asm,C,C++,etc) that runs on another processor is known as a cross compiler...

 

[thannara123]

yes i was mistaken. compiler .
I got the idea thanks .

Is there any IDE use most of the cross compiler can use on it ?

 

[errakeshpillai]

You can use Code Blocks.

I found a discussion that can be useful to you.
IDE for Cross Compiler

 

[bigdogguru]

The Eclipse IDE is another popular choice, particularly for ARM and PowerPC.
