Undefined cpp symbol __gnu_Unwind_Find_exidx

I am trying to statically link cpp library libsupc++.a on TizenRT OS (github.com/.../TizenRT).
However when I try to build the code for CORTEXM33 chipset using , I am getting the following undefined symbol error:

make[1]: Leaving directory '/root/tizenrt/os/arch/arm/src'
CP: tinyara.axf.hex
CP: tinyara.axf.bin
Verify ../build/output/bin/app1
Undefined Symbols in ../build/output/bin/app1
          w __gnu_Unwind_Find_exidx unwind-arm.c:0

Have not been unable to resolve this inspite of adding the definition of the API explicitly to the CPP/C code.
