C++ compiler setting in CCS v6.1

Hello,

         I am working with C++ library of wavelet and It is giving lots of error during linking process. Perhaps I could not enable c++ compiler setting. How can I enable the c++ compiler setting? 

I am getting following error

'Invoking: GNU Linker'

    I am unable to reproduce these diagnostics, so I am not certain what is going on.

    To build C++ code, you need to change arm-none-eabi-gcc.exe to arm-none-eabi-g++.exe .  I also find your use of the option -fno-exceptions to be suspicious.  Though I cannot prove that is the root cause of your problem.

    Thanks and regards,

    Hello George,
    did you compiled wavelet library sucessfully without any error? and How can I enable g++ compiler, I am getting any option to set it in CCS v6.1.

    No.  I am not familiar with that library.

    I didn't realize you were building in CCS.  I thought you were building from the command line.  From within CCS, there is no method for choosing between gcc and g++.  For compiling, it doesn't matter.  gcc and g++ decide how to compile based on the file extension.  file.c is a C source file, and file.cpp is a C++ source file, and so on.  For linking, you can control it by which libraries you choose.  In your case, add the library specification -lstdc++ to the link.  Even though gcc is used to link, adding this library makes it work.  The details on adding a library to a ARM GNU link in CCS are in this post.  Note you add the library name "stdc++".

    Thanks and regards,
