Re: Toolchain compilation problems

Well it was the truth, but not the full story. Some stories just go ever 
on, so at times you cut to the chase. But you want a longer story.

Well if you'll excuse me skipping over things, I'll skip the first pass 
of binutils, gcc, and uClibc. Going straight to the second pass these 
are the non sysroot configures used:

gcc-4.7.0 configure:

../gcc-4.7.0/configure --prefix=/home/arm --with-local-prefix=/home/arm 
--with-native-system-header-dir=/home/arm/usr/include 
--target=armv7-hardfloat-linux-gnueabi --host=x86_64-pc-linux-gnu 
--build=x86_64-pc-linux-gnu --enable-neon --with-arch=armv7-a 
--with-tune=cortex-a9 --with-fpu=vfpv3-d16 --with-float=hard 
--with-abi=aapcs-linux --enable-languages=c --enable-threads 
--enable-tls --enable-shared --disable-libgomp --disable-nls 
--disable-multilib --disable-libmudflap --disable-libssp 
--disable-libgomp --disable-libquadmath --with-headers=/home/arm/usr/include

binutils-2.22:

../binutils-2.22/configure --target=armv7-hardfloat-linux-gnueabi 
--host=x86_64-linux-gnu --build=x86_64-linux-gnu --prefix=/home/arm 
--with-lib-path=/home/arm/lib:/home/arm/usr/lib --enable-shared 
--disable-nls --with-libliberty

maybe tweaked ld with

make -C ld clean
make -C ld LIB_PATH=/home/arm/usr/lib:/home/arm/lib

Am just now retrying a sysroot vesrion, with the binutils in the gcc 
directory, so I do both at the same time. With what else I've learn 
think this should now work with sysroot as well - and as having sysroot 
was my preferred option, I'll now see if I can get it to work.

Thanks for your help,

David.
