[Buildroot] Error building arm toolchain: undefined reference to `raise'

[Buildroot] Error building arm toolchain: undefined reference to `raise'

[Michael Opdenacker]

Sorry for not replying to the original thread... I've just subscribed to 
the list.

I've just faced the same issue, in a very similar configuration.

When I use the latest uClibc snapshot, compiling stumbles on another error:

AS libc/sysdeps/linux/arm/sigrestorer.os
libc/sysdeps/linux/arm/sigrestorer.S: Assembler messages:
libc/sysdeps/linux/arm/sigrestorer.S:43: Error: invalid constant -- `mov 
r7,$((0x900000+119))'
libc/sysdeps/linux/arm/sigrestorer.S:63: Error: invalid constant -- `mov 
r7,$((0x900000+173))'
make[2]: *** [libc/sysdeps/linux/arm/sigrestorer.os] Error 1
make[1]: *** [lib/libc.so.0] Error 2
make[1]: Leaving directory 
`/home/mike/tmp/buildroot/buildroot/toolchain_build_arm/uClibc'

Still investigating...

Cheers,

    Michael.

[Buildroot] Error building arm toolchain: undefined reference to `raise'

[Tor Krill]

Hi,

I'm trying to build an up to date toolchain for our arm920t board, at91rm9200.
However compilation fails with a:

/home/tor/tmp/buildroot/build_arm/staging_dir/bin/arm-linux-uclibc-ld -EL -e
_start -z now -Bsymbolic -shared --warn-common --export-dynamic --sort-common
-z combreloc --discard-locals --discard-all --no-undefined -s

make[1]: *** [_dir_ldso] Error 2
make[1]: Leaving directory
`/home/tor/tmp/buildroot/toolchain_build_arm/uClibc-0.9.28'

I used latest possible stable versions,
 * gcc-4.1.1
 * Kernel headers 2.6.12
 * Binutils 2.17
 * no softfloat
 * Busybox snapshot
 * Default stable uClibc 0.9.28

Am i missing something here?

Regards

Hi,

Have a look at the gumstix buildroot (www.gumstix.org) for a patch called
uClibc-gcc-41-raise-error.patch, I think this will do the trick.

Thanks Philippe, this solved the compilation error.

To save time, here's the exact location of this patch:
http://svn.gumstix.com/gumstix-buildroot/trunk/toolchain/uClibc/uClibc-gcc-41-raise-error.patch

Cheers,

    Michael.

When/How does this patch (and other similar) get incorporated
into uClibC.org patches ?
Surely that is the most appropriate location ?
