OpenRISC gcc Porting Issues (uClinux Problems)
by Unknown on Oct 25, 2004 		Not available!
Hi Everyone,
I was able to check out the new version of gcc and now I am having
troubles with uClinux installation. I have cut and pasted the error I
got.

Any help is appreciated.

Thanks,

Balaji V. Iyer.

Hello Matjaz,
Opencores used gcc3.2.3 (atleast it wa the only version I found in
the
CVS directory) and I need 3.4.2 because there are a lot of
haifa-scheduler optimizations available in the 3.4.2 that is not
available for 3.2.3

thanks,
gcc-3.4.2 port is in the opencores cvs: http://www.opencores.org/cvsweb.shtml/or1k/gcc-3.4.2/ best regards, p. _______________________________________________ http://www.opencores.org/mailman/listinfo/openrisc

(uc)linux 2.0.x is very old. it is not recomended to compile old kernels
with very recent gcc compilers. i suggest you try with an older compiler
(gcc-3.2.3).

Matjaz,
If I can't use uclinux then how can I use gcc-3.4.2 to cross compile
to get an output? Is there a work around?

i'm not sure what you mean. uclinux is just an operating system. you don't
need it to have something running on the board or
simulator. for example you can try 'hello-world' (was posted on this
list some time ago) application which outputs something to the UART or you
can write your own.

if you'd want an operating system i recommend you try linux-2.4 also
avaliable in the opencores cvs.

best regards,
p.
