For now I suppose that you use KDS2.0 and you build application from here. If not, please add some details about your environment.
I guess that there could be conflict because you try loading the same library twice:
-l_mqx_stdlib and C:/Freescale/KSDK_1.1.0/rtos/mqx/lib/frdmk64f.kds/debug/mqx_stdlib/lib_mqx_stdlib.a
-l_mqx and C:/Freescale/KSDK_1.1.0/rtos/mqx/lib/frdmk64f.kds/debug/mqx/lib_mqx.a
-lksdk_platform_mqx and C:/Freescale/KSDK_1.1.0/lib/ksdk_mqx_lib/kds/K64F12/Debug/libksdk_platform_mqx.a
I would like to recommend keep just one instance of these libraries.
So, if you look at project properties - C/C++ build settings - Linker option you should add library as either Library or Other objects:


I see that you use C++ linker. Is your project compiled be C++ compiler?
If it is possible, could you please attach here your project, that we can test it?
I hope it helps you.
Have a great day,
