Problem using Mathwork's custom toolchain - Error during Simulink model build

I tried creating a Custom Toolchain named ‘MinGW64 | gmake (Custom)’ with MinGW compiler(4.8.2) in another directory,
(To be precise need to refer MinGW compiler path to a View in the GIT repository)
and configured that new toolchain with similar settings to that of Mathwork’s MinGW compiler(6.3.0) ‘MinGW64 | gmake (64-bit Windows)’.
Registered this toolchain after it passed the tool validation (tc.Validate) without any errors.
Created a Test model and used ‘grt.tlc’ Target and linked new custom target and customized new Toolchain.
Built the model, but couldn’t succeed with the build process.
The error message is,
..### Starting build procedure for model: sample_mdl ### Generating code and artifacts to 'Model specific' folder structure

end
I am not sure where I did wrong in the toolchain configuration.
Any suggestions are appreciated.
