MATLAB: Matlab lcc compiler giving error

Question

i installed microsoft sdk 7 version. using mex-setup i changed compiler to microsoft sdk 7. mexopts.bat file which is located in appdata is correctly updated from file mssdk71opts.bat located inside matlab folder in mexopts folder when i build model,it is always using lcc compiler only. i dont know how to do to resolve this problem

below i mentioned steps matlab does when i compile a model

### Starting build procedure for model: untitled
### Generating code into build folder: e:\New folder\untitled_grt_rtw
Warning: The model 'untitled' does not have continuous states, hence Simulink is using the
solver 'FixedStepDiscrete' instead of solver 'ode3'. You can disable this diagnostic by
explicitly specifying a discrete solver in the solver tab of the Configuration Parameters
dialog, or by setting the 'Automatic solver parameter selection' diagnostic to 'none' in
the Diagnostics tab of the Configuration Parameters dialog 
Warning: Unable to determine a fixed step size based on the sample times in the model
'untitled', because the model does not have any discrete sample times.  Picking a fixed
step size of (0.2) based on simulation start and stop times.  You can disable this
diagnostic by explicitly specifying a fixed step size in the Solver pane of the
Configuration Parameters dialog box, or setting the 'Automatic solver parameter selection'
diagnostic to 'none' in the Solver group on the Diagnostics pane of the Configuration
Parameters dialog box.

Which operating system are you using? If you are using Windows 95, Windows 98, or Windows ME then the program is command.com instead of cmd.exe

You might need to use

mbuild -setup

but I have not figured out yet when that is needed or not.
