I want to create a new project,but there is an error about multiple definition.

my steps as below:

1. S32DS--->file--->new---> S32DS Application project --->family S32k3xx and choose S32K344--->next--->done

2. copy static code from RTD1.0/plugins to my project, here I also copy plugins/platformxx/startup files.

3. define preprocessor macro "S32K344" and S32K3XX

4. declare header files

5.build project

It seems that the system doesn't get the right link file.

Hi@bowen_gu

Please try to delete Startup_Code,Linker_Files & include before copy plugins/platformxx/startup files.

why does system try to link "__start" twice?

Any update over this one ? As I am facing the same issue while creating a project in Release Mode in S32 DS 3.4 for the S32G274A device

For people that may run into this in the future.

This issue may be resolved by checking the "Do not use standard start files (-nostartfiles)" box under: Properties > C/C++ Build > Settings > Standard S32DS C(++) Linker > General
