Getting the following error:

error: failed to run custom build command for `librocksdb-sys v0.8.0+7.4.4`

Caused by:

This has been seen in the wild before in this issue by several people: #382 (comment)

Just curious what the solution is. We're unfortunately stuck using an old fork of a downstream package so I assume this issue has something to do with clang or one of the rocksdb dependencies being newer than what this version expects.

same error using clang 15

Same using clang 17 on Mac OS X , apple silicon.

[sam0x17]

also tried clang 14 to no avail on arch, and gcc/g++ 12

[pplanel]

Same here, clang 15 on apple silicon

[sam0x17]

updating to a newer rocksdb does fix it, which is what we had to do to get things working again in opentensor/subtensor#252 for everyone but the most out-of-date ubuntu

Same here, clang 15 on apple silicon同样的情况，在 Apple Silicon 上 clang 15
