Hi Arvind,
The CAN_MASTER_Example can be compiled without error on my PC. The example is in below folder (...\S32_ARM_v1.2\S32DS\S32_SDK_EAR_0.8.1\examples\demo_apps\FlexCan)


S32 SDK v0.8.1(EAR) is available as a part of S32DS v1.2 installer. You can download it from here:
http://cache.nxp.com/files/software_development_tools/ide-debug/S32DS-ARM.html
Have you try to "Clean Project" and then "Build" it again?
If the example still can't be able to compiled, would you please copy the error Description to here?

Best Regards,
Robin
