Compiling under uClinux

hi,

is that possible to compile source codes under uclinux itself, i.e is there a gcc version that run under uclinux?

warm regards

Maybe you can try Forth instead. It is tiny and fast. Good for embeded.

There are ports of perl and python in uClinux-dist.

I&#39;ve tried python, and it is running on nios2.

If you still want gcc, you should read gcc.gnu.org .

Hi hippo,

thanks for your reply,

I&#39;ve took a look and it&#39;s seemingly for ColdFire processor.

Yes I want gcc cause as I see, the majority apps are to be compiled with.

I read gcc.gnu.org and I can&#39;t say it&#39;s helping

Look in the porting/bootstrapping of gcc.

But you should think twice. Though comiple C program on a nios2 is possible. You need to port a lot of tools before gcc build. It is not pratical with the limited speed and resource on nios2. Did you ever compile on a 66MHz 486 PC?

The uCforth is for coldfire uClinux. It can be ported to Nios2.

Forth had been used as firmware of Power Mac.

Python is ready to run. Perl has some compile errors, but can be fixed.

Why do you want to compile program on Nios2?

Do you want to develop program without a PC host?

Are you tired of downloading? u-boot,nfs,ftp,tftp,telnet are better solutions.

Or just want to learn about gcc?

Well, that&#39;s a point I have not consider, you&#39;ve seen right!

And talking about uCforth, is it possible to compile my old apps with ?

Sorry to ask, I&#39;m not a linux geek, but what have python and perl to do with compiling source code ?

I want to avoid using cross compiler and emulator so I can avoid multiple errors in compilation, I want to let down the nios terminal too and communicate directly with the board via ssh and so I&#39;ll compile my apps under µClinux itself.

My final goal will be to design my custom board and embed my system on(a webserver) so to be autonomous system.

It is clear. You will compile on PC host and test your programs on nios2.

Forget all about python,perl, and forth. Nor should you compile on nios2.

If all the works are inside your lab, then you don&#39;t need ssh. It is easier and faster to use telnet.

You can telnet your nios2 and get the files from your PC host via ftp.

I don&#39;t use jtag download and terminal, too. ( I used them only to write the guide. )

It is much faster to use ftp or nfs.

About compilation errors, you should find out where they come and resolve them. There is no big difference in the gcc itself, whether for i686 or nios2. Most problems used to be library and header.

By the ways, did you get the buildroot toolchain running on Linux?

You might develop and test your programs on PC linux first, and then port to nios2.

How can you upload the kernel and the file system into flash memory without jtag, and without the terminal, how µClinux will start ?

Unfortunetly, NO. I get those errors all the time and I passed over 3 days trying to make it but no way! That was really disappointing especially I&#39;ve really loved working under Linux, there&#39;s really tons of things to learn about.

I wrote tools to download my custom boards. It was before jtag and IDE available.

You can use u-boot and serial uart. Once setup, you don&#39;t need jtag.

You may try Slackware (which is old and stable), or other Linux distributions. You might find somethings you like.

Could you please direct me where to find the way to do so, actually I wanna upload via Ethernet instead of using uart.

You can use u-boot and tftp to download via Ethernet.

Both of them are experts of u-boot.

And if I won&#39;t use u-boot, I want to create my own tool for uploading via Ethernet, any suggestion ?
