linker issue - undefined reference error
i am trying to build a software by using a cross tool chain, and at the end of the build at linking stage, i get the following errors..
/opt/atmel/gcc-4.1.2-uclibc/bin/../lib/gcc/arm-linux-uclibc/4.1.2/../../../../arm-linux-uclibc/lib/libstdc++.so: undefined reference to `__towupper_l'
and so on ...
and when i checked the nm for libstdc++.so, it has these symbols with U type(means undefined). How can this problem be fixed. Can i refer this library to any other library that has these symbols. if so how ???
thanks in advance,
