@brad0 I was able to checkout your branch and compile it. However, at the moment I keep running out of memory when running gmake check (I suspect that is unrelated to your change). My system (OpenBSD 7.6 x64) has 32GB or RAM and 16GB Swap file. Have you been able to run check?

@adamretter You would have to use ulimit -d to increase the datasize. Make sure to add the user account to the staff login class. You can do so with usermod -L staff [user]. The default value is quite low.

I have not tried that. I tried running gmake check and it would not build on either amd64 or arm64 with the same linking issue..

@brad0 I don't get those errors. Instead I get this:

./db_bloom_filter_test >&t/log-db_bloom_filter_test

ld.so: db_bloom_filter_test: can't load library 'librocksdb.so.9.8'
Killed

Is that the version that is built? so.9.8? It looks like the dynamic linker having difficulty finding the built copy of librocksdb. Where is it relative to the db_bloom_filter_test test?

Maybe this is helpful?
