hi all
i would like to know about cross compilation.

1.what is meant by cross compilation.
2.what is the use and where can we use and can i use it fedora 9.
3.how to do it(step by step).
4.i have to cross compile "hello gtk" (helloword.c).

any help it should be appreciable

cross compilation is basically your Host Platform/OS/Kernel and the Target platform/OS/Kernel for which you are compiling your source are Different........

And there is always Cross tool chain (if needed) is available............

1. A cross-compiler is a compiler which can build software intended to run on the same operating system but a different CPU, or on a different operating system (with the same or different CPU).

2. The traditional use of a cross-compiler has been to build software for a less capable computer using software on a more capable computer (compiles faster, more convenient to use, etc). For example, some versions of the Macintosh System were built on a Cray supercomputer. You can build your own cross-compiler to do things such as build an operating system and software for an ARM CPU - this is fairly popular in the world of "embedded" computing. If you really feel like it, you can even use a compiler on an Intel Pentium computer running Linux to build software for a PowerPC computer running OSX Leopard.

I have no idea if there are pre-built cross-compilers on Fedora9.

3. See the GNU GCC documentation on cross compiling; you can find it via the FSF website. You can also go to the Linux From Scratch project and look at the documentation of the CLFS subproject; that gives you an abridged version of how to build a cross-compiler.

4. I have no idea what you're talking about. Cross compile what program on what computer for what other computer?

hey! good explanation.

i seen the word helloworld in the link and i did not understand the tutorial it self.
