Hello all,

I use CANOE API in Simulink and build my model with system target file cn.tlc. But it always occurs include file errors during building progress. For example, following error occurs:

D:\MATLAB\rls2017b\rtw\c\src\rt_logging.c(21): fatal error C1083: Cannot open include file: 'stdlib.h': No such file or directory

But if I change the include file path with absolute path, the problem is solved. But another error is created, because other include file is included in code, for example #include <string.h>.

It seems that the link between compiler and head file is invalid. How can I fix this, thanks a lot!

PS: Matlab version is 2017b and compiler is Visual Studio 2017 professional.
