Re: Errors while crosscompiling a mips toolchain under OSX

[Guylhem Aznar <crossgcc at guylhem dot net>]

Hello

A quick follow up. I studied Khem's scripts and I'm now using uclibc
and similar stages, but once again failling at gcc stage 2. I tried
with and without threads-  same problem ,

Initially the phase 2 gcc complained about missing headers because I
had (among other things - due to an inherited uclibc-config) a wrong
DEVEL_PREFIX instead of / as expected by Khem's scripts. My
KERNEL_HEADERS is fine (="/gcc/sysroot/usr/include") but I see no NR
in /gcc/mips-fritzbox-linux-uclibc/include/unistd.h.

It though it might be the cause of the problem (
http://kerneltrap.org/node/7373 ) since I tried with a 2.6.19.2 kernel
to match the version currently running on the hardware, but further
trials with very recent kernel didn't improve the situtation.

Gcc really doesn't like the uclibc headers

I thought I should use a patch with gcc?

Here are the lines  I did use:

I thought there might be a problem with them so I tried to follow Khem
script line by line, but I got the same problem :

Fails with:
../../../../src/gcc-4.5.3/libgcc/../gcc/tsystem.h:87:19: fatal error:

As you can see there are headersm but maybe not in the place where
they are expected??

*$ find /khem/|grep stdio.h

So I tried with -I/khem//obj/uclibc-headers/include/bits but I got then:

                 from ../../../../src/gcc-4.5.3/libgcc/../gcc/libgcc2.c:29:

/khem//sysroot/usr/mips-linux-uclibc/usr/include/sys/types.h

So I tried again with
-I/khem//sysroot/usr/mips-linux-uclibc/usr/include but I got:

In file included from ../../../../src/gcc-4.5.3/libgcc/../gcc/tsystem.h:87:0,
                 from ../../../../src/gcc-4.5.3/libgcc/../gcc/libgcc2.c:29:

/khem//sysroot/usr/mips-linux-uclibc/usr/include/features.h:187:33:
fatal error: bits/uClibc_config.h: No such file or directory
compilation terminated.

In the end, I tried with /khem//obj/uclibc-headers/include which gave
me the very same error I had with my scripts.

Once again a hint or a pointer would be appreciated.

I'm attaching the full log + the uclibc config in case I made another
obvious mistake.
