RE: [openrisc] Running ORPsoc simulator

["Robert Cragie" <rcc@jennic.com>]

Hi Simon,

OK - I have finally got it to build (not tested it yet though). As
suspected, the prefix not being put on crt0.o was the problem.

I reconfigured gcc-3.1, putting a '/' at the end of the prefix - the only
difference I could find.
I rebuilt gcc-3.1
I went to uclinux/userland/init and typed 'make' - and it worked! :-). The
command line appeared as you saw it as below,

So I rebuilt everything, putting a '/' at the end of all the prefixes.
And now it didn't work :-( - the same problem as before.

In gcc3.1, I removed config.cache (perhaps I should have removed
config.status as well?), configured and did 'make all install' - still
didn't work
In gcc3.1, I configured and did 'make clean all install' - still didn't work
In gcc3.1, I configured, modifying the prefix to not have a '/' at the end
and did 'make all install' - and it worked! :-)

So the conclusion I have come to is that you have to reconfigure and build
gcc-3.1 for a third time, making a small change to the prefix e.g. by
adding/removing a '/' at the end. I cannot explain this, but it will do for
now.

Thanks everybody for their help.
