are you sure this was a mistake? It has a semantically different meaning now.

yeh, its just a kernel thing. If it overload it will duplicate a libpros.a in the project root directory.

So the template rule in common.mk is no longer used then, since it's being overridden in user project Makefile? Can it be removed, or is it used to build the kernel? If so, should it be in the kernel's Makefile?

It's only being used by users. There's no template rule in the distributed makefile, only in common.mk.

Ok, so the kernel build uses this template rule here, and user project builds use the one in common.mk? Then shouldn't the one in common.mk be moved to template-Makefile? If it's not used by both, it shouldnt be in common.mk, right?
common.mk
Outdated

Can we figure out a better way to do this than duplication? Also should LNK_FLAGS be LNK_FLAGS_HOTCOLD or something?

Yes it should be in kernel because it's just linking issue. |

I make it |

Could I have an explanation of what the linking issue is and how this solves it? And also probably set it as the top-level PR description, |

The linking process didn't work initially because the linker was discarding unused symbols from liblvgl.a. Adding |
|
/azp run |
|
Azure Pipelines successfully started running 1 pipeline(s). |
|
Ok, can you add that explanation as a comment in the makefile? |
|
So, if I'm reading this correctly, the entirety of liblvgl is put in the monolith? The binary size is going to balloon. Additionally, what if one generic template overrides a weakly declared symbol in another template? Is that going to work? The changes in this PR is specific to liblvgl |
