RE: gcc-3.0.4, powerpc

["Josep Puigdemont (ETX)" <Josep dot Puigdemont at etx dot ericsson dot se>]

Hi!!

Thanks for the welcome to the "exciting(?) world of crosscompiling".

I think I did it! Thanks for your help!

Well, the problem, I think, was that I was using the wrong sources, I used gcc-3.0.4.tar.gz, instead of the "core" version. I don't really know what's the difference, but now it seems to work, or at least make ends without any errors. Cool.

Next is to build the library... I'm already shaking, but I'll go through it!

I still don't really know much about the "target", I see that there're many different powerpc kinds... I compiled for eabi, but I don't know what's that, or I'm missing something. I think I'll repeat the steps for powerpc-linux, and powerpc-elf, now that it works, it is even fun. Can someone brief me the difference between them? Thanks again!

The FAQ I read was at
http://www.objsw.com/CrossGCC/index.html

The other links you gave me are very welcome also! Nice, nice nice!

Thanks a lot a lot a lot!

Use the web Luke !

The targets are all explained on the following page
http://gcc.gnu.org/onlinedocs/gcc-3.0.3/gcc_3.html#SEC3

(search for "Hardware Models and Configurations")

Well, your libiberty problem is a common one.
Which FAQ did you follow?

I managed to build a C, C++ compiler with Newlib (also on RH7.2) using
Bill's FAQ which can be found here:
(the libibery problem is explained there)
http://crossgcc.billgatliff.com/

A small note: 3.0.4 is getting more stable, but 2.95.3 is a proven
sollution.
I like the new optimisation tricks of the 3.x series, as well as new C++
features. And I like to tinker with it from time to time.
But when I make new commercial firmware for a board, I'm still using 2.95.3
until the 3.x branch is considered stable enough.

Let us know if it worked for you.

Best regards,
Jan
