[Buildroot] using crosstool-ng with glibc and buildroot

[Florian Schimmer]

Hello, 

I'm not able to use the builds of crosstool-ng in buildroot as an external toolchain. 

Buildroot Error: 
Checking external toolchain settings
Cannot find cross-compiler /home/flo/x-tools/x86_64-unknown-linux-gnu/x86_64-unknown-linux-gnu/bin/-gcc
make: *** [/home/xx/xx/buildroot/buildroot-2009.08/build_x86_64/stamps/ext-toolchain-installed] Error 1

Buildroots want's a prefix like x86_64, but crosstools-ng builds a gcc without prefix 

if i add a symlink to gcc with the prefix, i get this output: 
Incorrect selection of the C library
make: *** [/home/flo/Arbeit/buildroot/buildroot-2009.08/build_x86_64/stamps/ext-toolchain-installed] Error 255

Buildroot doesn't find the library.

ext-tool.mk : 
if ! test -f $${SYSROOT_DIR}/lib/ld-linux.so.* ; then \
		echo "Incorrect selection of the C library"; \
		exit -1; \
	fi; \

but crosstools output for ld is:
/lib/ld.so.1 and /lib/ld-2.9.so

what can i do? 

thx
flo

Instead of pointing Buildroot
to /home/flo/x-tools/x86_64-unknown-linux-gnu/x86_64-unknown-linux-gnu/,
could you point it to /home/flo/x-tools/x86_64-unknown-linux-gnu/ ? The
bin/ directory in this directory should contain the cross-compiling
tools with prefix.

Can you give me the full list of libraries in $${SYSROOT_DIR}/lib/ ?
Here, on an ARM toolchain, I have a lib/ld-linux.so.3 symbolic link.
Maybe it's different per architecture, in which case I could relax the
test.

Sincerly,

Thomas
