I want to use #include <stdio.h> and #include <math.h> but CCS4 can't find them unless I specifically add the directory they're in to the list of directories to search when looking for headers. Must I always specifically tell this compiler to look in that directory? What kind of compiler can't find stdio.h?

Hi Shannon,

I think you'll find that ALL compilers needs to be told their search paths!

I have never seen that issue. Is this a regular CCS project or did you write your own makefile?

Might be showing my age here, but every compiler I've used in the past would treat <stdio.h> and "stdio.h" differently. For "stdio.h" a search path would have to be specified if the file wasn't in the current directory but for <stdio.h> it would know where to look, eg, /usr/include on most UNIX systems. Maybe I missed an option during the CCS installation.

Please zip and attach a simple project.

When a new project is created in CCS, an include search path to "${CG_TOOL_ROOT}/include" is automatically added. This should resolve to the /include folder within the codegen tools folder which contains stdio.h and math.h. In your project properties, under C/C++ Build->Compiler->Include Options, do you not see this path added to the --include_path?
