Error(s) encountered while building "rtwshared"

Hello. i have a problem with code generation in simulink. The code doesn't build and I get the following error everytime i try to build it:

Can anyone solve this porblem?? Thanks

Can someone answer this! I have the same issue.

[Jun Yang]

help! same situation!

[zesen]

i have the problem too

error: floating constant is out of range

It sounds to me as if some code attempts to initialize with a double precision constant, into an object that is marked as single precision, and the constant initializer is outside of the permitted range of single precision.

This problem is related to the libraries that you used in your model. For example, I was trying to build a model based on Extended Kalman Filter block and this error occured. I changed my simulink model to mathematical and matlab function blocks, so i could build the code of my project. When you want to use code generation, it is important to consider the simulink blocks that are supported by code generation. You can find more in the following link:

The link doesn't seem to work. I there a way to find out or debug the root cause for this issue?

[Aditya Padmanabha]

Hi @Srikar,

Please share the model, the MATLAB release details and full diganostics log for further investigation.

Thanks,

Aditya
