Cross-compiling v/s cross-building


I understand the meaning of Cross-compiling as explained here. But what do we mean when we say cross-building? Are those two different terms? Or one is a subset of other or something like that?

Thank you.

Yes, you have to first build your cross-tools, so, I guess, this is what they call cross-building.

For example, I recently built cross-gcc to produce executables for Windows under Linux, then I used the cross-gcc under Linux (i.e. cross-compiled) to produce an executable for Windows.

Thanks Sergei. I think I am beginning to understand the difference. So basically before you can do cross-compiling you need build a cross-tool which will do your cross-compiling, right?

On a side note, if it is OK with you can you point out the guide which you followed to produce Windows executable under Linux?

http://www.profv.de/programme/ ->
http://www.profv.de/mingw_cross_env/ ->
http://www.profv.de/mingw_cross_env/README.html .

Download and build (after reading the above) - just

make gcc

after editing Makefile. You may build much more than just 'gcc'.

Then you build essentially the same way as for Linux, just using the full path to cross compiler, e.g.

~/mingwi686/bin/i686-mingw32msvc-gcc hello.c -o hello.exe
.

You can first try under 'wine':

wine hello.exe
.

I've been dealing so far with non-GUI Windows apps, but there are examples of GUI ones too.
