uClibc++ application compilation error

[Khem Raj]

You are using a gcc which is configured for glibc. Thats your biggest 
problem here. If you want to use uclibc then you should configure other 
toolchain components to be uclibc aware especially gcc and ld/binutils.

You can refer to buildroots toolchains and I would suggest that you 
build the complete toolchain configured correctly for uclibc.

Thanks
