Hi all,
I am trying to import a DCAN example project for the AM437x evm into CCS and I am experiencing some issues.
When I import the project, a few of the "Includes" paths can not be found. I also receive a warning that the build-varaiable PDK_INSTALL_PATH can not be resolved. All the missing paths are also linked to this variable, as you can see from the following screenshots (Project->Properties->build->GNU Compiler->Directories):
):
The warnings can be seen below:
When I edit the missing paths to be C:\ti\pdk_am437x_1_0_14\packages\ti\starterware\examples\dcan instead of linking it to the PDK_INSTALL_PATH variable, all warnings disappear. However when building the project, I receive the error that there is an undefined referenence to __kill. You can refer to the build log below:

I think it is quite obvious that the error comes from the PDK_INSTALL_PATH variable, but I would be greatly appreciated if you could provide some assistance to solve this problem. I look forward to hearing from you as soon as possible. Kindly let me know if I should forward the archive file as well.
I am using CCS 9.1.0.00010 and Processor SDK RTOS 5.03.00.07.

The generated project is designed to use the PDK_INSTALL_PATH variable. I would add that variable to the project, as a Linked Resource Path Variable, and set it to the correct path.
Example:
This should properly set up all the paths of the project and you should be able to build it successfully (worked for me)
Thanks
