libstdc++ DSO missing

[Alex]

Hi,

I intergrated my application to buildroot. Complie is successfull by 
when linking I get errors:

x86_64-buildroot-linux-gnu/sysroot/usr/lib64/libstdc++.so.6: error 
adding symbols: DSO missing from command line

Are libraries missing from buildroot environment?


Additional I get warnings that some .so files not found, but they are 
available in output/build/<Tool>/lib

But I included this path by $(@D)/../<Tool>/lib


What is missing in build command?
Any ideas what is missing or what to do to handle the DSO missing error???

Thanks!


King regards,

Alex
