thank you it worked for me but new issue came.

You can set the include path in Project Properties > C/C++ Build > Settings:

Where is alt_cache.h located? I don't see it in the project.

Hi i am attaching the image.

please help on this issue, because i am trying compile freertos source code on arm ds IDE.

If possible please share complete steps how to import freertos project on arm ds ide

For instructions on installing the toolchain, see
https://developer.arm.com/documentation/101470/2010/Configure-Arm-Development-Studio/Register-a-compiler-toolchain

For finding .h files, use -I<path_to_file> to add that path to the include search path.

Hi Andy Neil after installation of ARM-ds5 IDE, i installed gcc-linaro-7.5.0 toolchain.

But arm ds ide not able to detect the path, manually i gave the path .

During  compiling  make command not  able to detect header files which are in same folder  throwing error like

"Description Resource Path Location Type
fatal error: alt_cache.h: No such file or directory cache_support.c /RTOSDemo/Altera_Code/SoCSupport line 31 C/C++ Problem
"

That's just the "summary" telling you that the build was unsuccessful.

You need to look further back in the build output to find the specific error messages that give you full details of what failed.
