Hi All,
Has the uClibc ported for the gcc 3.4.2? If not, is it going to be
ported in the near future?

Thanks,

Balaji V. Iyer.

yes, the uclibc in or1k/linux/uClibc (or something similar) directory

HI All,
Thank you for the swift reply. To build this, I assume that I need to
checkout or1k/linux/linux2.4 as well. I only have the older tutorial so
I didn't find the same changes as I saw there. So pretty much this is
what I am doing

1. copied the "DOT_CONFIG.OR32" to ".config"
2. Set where ever it says "LIBGCC=" to my path for libgcc.a
3. make oldconfig
4. Make dep
5. make all

6. went into ucLibC directory
7. changed "DOT_CONFIG.OR32" to ".config"
8. Updated the kernel source and DEVEL_PREFIX in the .config to the
appropriate values (1st one is where the linux-2.4 is the 2nd one is where
I wnat it to be installed, in my case /tmp/or32-uclinux).
9. Make all install
10. went to my b-gcc directory
11. removed my current config files and make files and reconfigured it.
12. make all install

then I ran a test program with that has a main function and all it does is
puts("Hello World."); but when I ran

or32-uclinux-gcc test.c

I get the following error:

/tmp/or32-uclinux/lib/gcc/or32-uclinux/3.4.2/../../../../or32-uclinux/bin/ld:
cannot open crt0.o: No such file or directory
collect2: ld returned 1 exit status


What am I doing wrong?

Any help is appreciated.

Thanking You,

Yours Sincerely,

Balaji V. Iyer.

you're on the right track... just make links in

/tmp/or32-uclinux/lib/gcc/or32-uclinux/3.4.2

that point to

crt0.o, crti.o, crtn.o, libc.a and others that you compiled in
uclibc. (i'm not sure why ld can't find them)

Thank you Matjaz for your quick reply. I did what you suggested and now I
got a different set of errors. Here they are.

/tmp/or32-uclinux/lib/gcc/or32-uclinux/3.4.2/../../../../or32-uclinux/bin/ld:

I am not able to make sense of it. Any help is Appreciated.

Thanking You,

Yours Sincerely,

This is very annoying linker problem. Just extract these symbols from
libc.a (using 'ar') and link with them explicitly...

Same issue here.
Still 0 time during the week to do some more bits for new binutils.
