Interoperability for c++ between armclang and gcc(linaro)

Hi;

I have built 'Compute Library'  as said in Bare Metal Building section of documentation by using Linaro toolchain on Ubuntu. I'm targetting bare-metal.

On another machine, I want to use this library but this machine has an Arm Compiler 6 version and I want to use it as my toolchain. 

While linking, I get errors like 

L6242E: Cannot link object <objname> as its attributes are incompatible with the image attributes.

it says packed-enum is not compatible with enum_is_int.

I tried to play with  compiler option, -fshort-enums, -fno-short-enums but couldn't succeded.

So my question is, is it possible to call methods from a library that is build by Linaro Toolchain from another executable that is  build by Arm Compiler 6(armclang).

If possible, Which options should I set?
