Thanks.

Did you test that the various libraries also work?

What is the advantage of the pkg'ized zlib as opposed to the one provided by the Rumprun base build?

Please rebase your changes clean them up, e.g. s/JANSSON/NET/ doesn't belong into the zlib commit.

I invited you to the github rumprun-packages team.

@anttikantee Thanks.

• I'll rebase my changes
• I did not know zlib shipped with rumprun. Also, how do I refer to packages provided by the base build? I know i can refer to the rumprun-packages with RUMPRUN_PKGS_DIR. nvm, I found out about RUMPRUN_SYSROOT.

The base libs and headers should automatically be picked up by the compiler, so simply -lz should work.

@btbytes are you planning to merge this, or are there still issues?

(one might also argue that you rebased too much, one commit per new package would be the logical granularity, but let's not view that as a showstopper)
