HERO: Compiling OpenMP examples with only=pulp - darbyshaw - 08-30-2023
Hello,
I am trying to compile the mm-small example in https://github.com/pulp-platform/hero/tree/master/openmp-examples/mm-small. I would like to build it only for the PULP accelerator.
For that I run make only=pulp. I get the following error:
herov2/pulp/sdk/pkg/sdk/dev/install/include/archi/pulp.h:31:10: fatal error: 'archi/chips/PULP_CHIP_STR/pulp.h' file not found
Please could you help me identify the source of the problem.
Thank you!

Reviving this question
It seems like some mm-small, mm-large, and dma-perf are not buildable without the archi/chips/PULP_CHIP_STR/pulp.h file. After going through the build process for Hero, the only directory under archip/chips/ is bigpulp. Is there a way to build the PULP_CHIP_STR directory, or use a different pulp.h that's called from include/archi/pulp.h?

This is a configuration issue rather than a missing build step.
As I know, in PULP Platform, PULP_CHIP_STR is a macro that resolves to the selected chip name at compile time. It’s not something that generates a directory automatically.

Ah, got it—so I just need to make sure PULP_CHIP_STR is set correctly in the build configuration to match an existing chip folder, rather than expecting it to create a new directory automatically.

Could you explain it in more detail? I don't quite understand the issue.
