uClinux question

[Altera_Forum]

Hello, 

 i just started to work with uClinux on an altera eval board.  I have a question regarding uClinux.  Does uClinux when running on a nios system have it's own compiler built-in?  Particularly what compiler do application on uclinux use?  I,m a just a beginner and would like to learn this.    Roman

uClinux running on board doesn't have GCC included in. Applications must be cross-compiled on a host Linux machine using Nios II binary tools (same used to compile kernel).  

 These are the precompiled tools.  http://www.niosftp.com/pub/gnutools/nios2gcc-20080203.tar.bz2 (http://www.niosftp.com/pub/gnutools/nios2gcc-20080203.tar.bz2)  So, your application can be added to your system in two ways:  * Adding application during kernel compilation.  * Adding the compiled application to your uClinux file-sytem through a storage device (USB pendrive, SD card) or a Network filesystem.

I suppose it is somehow possible to ccross-compile the gcc compiler to have it run on the NIOS itself, such as there is a Debian Linux distribution that runs on ARM and can d/l additional packets in source code and compile and install them.  

 But I don't think anybody would bother to do that for a deeply embedded arch like NIOS, as it does not make much sense.  -Michael

This means to rebuild the 'nios2gcc' on Nios system....:p  Kazu
