Hi,

   

My project compiles just fine in debug mode, but if I switch to release, it tells me for example:

   

Build error: undefined reference to `cos'

   

It does the same for my other math operators.

   

Any ideas?

   

Thank you,
Tom

Include the math library "m" in release configuration as in debug configuration

Yup, that would be it.

   

One more question, switching from Debug to Release did not significantly alter program size.  Is this normal?

   

I am pushing the FLASH limit (97.5%), and am trying to pare things down a bit.

   

Thank you,
Tom

Tom, you ought to verify setting for compiler->optimization is set to "size".

   

97% looks really tough, is there a chance that we can have a look at your project to see if there is something that can reduce code usage.

Hi,

   

Unfortunately both debug and release are at 'size' already.  

   

I do not feel comfortable posting the project, and I will probably open a case in regards to this.

   

Thank you for your assistance.

   

Tom
