error: Variably modified ‘root’ at file scope #66

Closed hanvo closed 11 months ago

hanvo commented 11 months ago

Hi,

I am not sure if this an issue that can be assisted here or not. But recently I tried to build my project in a Docker image with centos using colima on a mac. I am getting this issue while building 

  include/jemalloc/internal/rtree.h:106:19: error: variably modified ‘root’ at file scope
    rtree_leaf_elm_t root[1U << (RTREE_NSB/RTREE_HEIGHT)];

I was able to cross reference this with an issue that looks similar to mine here: https://github.com/jemalloc/jemalloc/issues/2318#issuecomment-1214832157

Is this something that could be applied as a workaround here in tikv-jemallocator?

I am unsure if anyone else has run into a similar issue. Below are detailed stderr output

Env: Gcc Version 7.3.1 Docker image: Centos

Thanks in advanced!

Yes, just run env JEMALLOC_SYS_WITH_LG_VADDR=<whatever_you_want> cargo build.

@BusyJay -- Thank you for the advise! That seemed to do the trick. But as for the value that is set is a bit mysterious to me. Do you have an idea the methodology on how to select a number? I've dug through a few github issue threads and it seems like the 2-3 posts I've seen suggest 48. But I can't pinpoint where that value came from. Thanks again for the time!

BusyJay commented 11 months ago

On x86_64 (and aarch64), not all addresses are used. Typically, on x86_64, only 48 bits out of 64bits for addressing. Also check https://en.wikipedia.org/wiki/X86-64.

Thank you for your reply and explanation! Closing.
