Hi

Are you trying to build one of the SDK example projects? What SDK version are you using?

ret_code_t is defined in the sdk_errors.h header file in the SDK. Please make sure that it is included in the following path: C:\...\YOUR_SDK_FOLDER\nRF5_SDK_17.0.2_d674dde\components\libraries\util\sdk_errors.h

Best regards,

Simon

sdk 17

[Piyush_9536]

yes ret_code_t is defined there as a name(datatype) of structure

And have you added it as part of your preprocessor definitions? Are you building one of the example projects in the SDK or have you made a project from scratch? We strongly suggest using one of the existing example projects as a template that should be compiling and building successfully from scratch. 

Also, if you're using SDK 17.0.0, it is strongly recommended that you switch to SDK v17.0.2 instead, which is a bug fix release replacing v17.0.0.

Best regards,

Simon
