link errors

Hi,

 

Just as background, This is an integration project. The project I got is a makefile project and we use HEW as debugger only.

Also Refering to this post:

https://renesasrulz.com/hew/f/hew-forum/3032/linker-errors-in-_flshbuf-and-malloc

 

I get  these errors after adding some c++ files to the project.

** L2310 (E) Undefined external symbol "_abort" referenced in "error"
** L2310 (E) Undefined external symbol "_sbrk" referenced in "malloc"

 

These are stdlib symbols which I don't use to my best knowledge, furthermore I don't use stdio function which could call these, like printf etc...

so I don't know how to solve this issue. Does someone have an idee?
