Hi,

This is Kumar. I have been trying to create a x86_64 toolchain using
crosstool-ng-1.23.0 but running into an issue where shared libraries in the
toolchain depend upon both toolchain and system libraries.

After creating the toolchain, I looked at the *ASAN *library dependencies.
Here is the output:

*kumar@kumar-vb:~/software/toolchain/x86_64-linux/gnu-6.3.0/x86_64-unknown-linux-gnu/sysroot/lib$
pwd*
*/home/kumar/software/toolchain/x86_64-linux/gnu-6.3.0/x86_64-unknown-linux-gnu/sysroot/lib*

*kumar@kumar-vb:~/software/toolchain/x86_64-linux/gnu-6.3.0/x86_64-unknown-linux-gnu/sysroot/lib$
/usr/bin/ldd libasan.so.3.0.0 *
*    linux-vdso.so.1 =>  (0x00007fff9a592000)*
*    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f163e88f000)*
*    librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f163e687000)*
*    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0
(0x00007f163e469000)*
*    libstdc++.so.6 =>
/home/kumar/software/toolchain/x86_64-linux/gnu-6.3.0/x86_64-unknown-linux-gnu/lib/../lib64/libstdc++.so.6
(0x00007f163e130000)*
*    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f163de27000)*
*    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f163da5d000)*
*    libgcc_s.so.1 =>
/home/kumar/software/toolchain/x86_64-linux/gnu-6.3.0/x86_64-unknown-linux-gnu/lib/../lib64/libgcc_s.so.1
(0x00007f163d84b000)*
*    /lib64/ld-linux-x86-64.so.2 (0x000055a9398f9000)*

Shouldn't libc.so.6, libm.so.6, libdl.so.2, librt.so.1, etc., depend upon
libraries in the directory
/home/kumar/software/toolchain/x86_64-linux/gnu-6.3.0/x86_64-unknown-linux-gnu/lib/../lib64/?

Please find my config below (I'm sorry I'm unable to send it as an
attachment). Is there a config option that I need to enable or disable?

You probably have the libraries on your host with the same name as you 
target toolchain has. Host ldd has no idea that these libraries should 
be looked for in ~/software/...; it just searches the standard path.

This shouldn't be a problem since you are not going to run the target 
binaries on your host, typically.

If you want to check dependencies of a target binary, try the xldd 
script installed by the crosstool-ng.

Alexey.
