[QUESTION] Could you have a document for the environment setup? To avoid compilation error.

When I download the src code to my local Ubuntu 24.04 LTS and follow the README to compile the src code, I encounter errors when compiling the deps/rocksdb:

db/db_impl/db_impl.cc: In member function ‘virtual rocksdb::Status rocksdb::DBImpl::FlushWAL(bool)’:
db/db_impl/db_impl.cc:1441:23: error: redundant move in return statement [-Werror=redundant-move]
 1441 |       return std::move(io_s);
      |              ~~~~~~~~~^~~~~~
db/db_impl/db_impl.cc:1441:23: note: remove ‘std::move’ call
db/db_impl/db_impl.cc:1445:23: error: redundant move in return statement [-Werror=redundant-move]
 1445 |       return std::move(io_s);
      |              ~~~~~~~~~^~~~~~
db/db_impl/db_impl.cc:1445:23: note: remove ‘std::move’ call
db/db_impl/db_impl.cc: In member function ‘virtual rocksdb::Status rocksdb::DBImpl::LockWAL()’:
db/db_impl/db_impl.cc:1562:19: error: redundant move in return statement [-Werror=redundant-move]
 1562 |   return std::move(status);

I have to set the following environment variable.

export CFLAGS="-Wno-error"

Then I face another error when compiling rocksdb.

'uint8_t' is defined in header '<cstdint>'; did you forget to '#include <cstdint>'?

To solve this I have to downgrade the gcc from gcc 13 to gcc 12.

It would be nice to have a document for the environment setup, the library, gcc version, CFLAGS etc....

Set the following env variables to allow CXX and CC point to g++-12 and gcc-12:

export CXX=g++-12
export CC=gcc-12
