Ubuntu 安装和编译

安装依赖：

sudo apt-get update
sudo apt-get install -y build-essential git cmake libgflags-dev clang-format libsnappy-dev zlib1g-dev libbz2-dev liblz4-dev libzstd-dev

克隆 RocksDB 仓库：

cd ~/repos
git clone https://github.com/facebook/rocksdb.git
cd rocksdb

（推荐）编译共享库并安装：（生成 .so 文件）

# make clean
PORTABLE=0 DEBUG_LEVEL=0 make shared_lib -j16
sudo DEBUG_LEVEL=0 make install-shared

（或者）编译静态库并安装：（生成 .a 文件）

PORTABLE=0 DEBUG_LEVEL=0 make static_lib -j16
sudo DEBUG_LEVEL=0 make install-static

默认安装到 usr/local/lib，可以检查是否正确安装：

ls -hal /usr/local/lib/librocksdb.*

输出形如：

/usr/local/lib/librocksdb.so
/usr/local/lib/librocksdb.so.10
/usr/local/lib/librocksdb.so.10.5
/usr/local/lib/librocksdb.so.10.5.0

确保动态链接库能被加载：

sudo ldconfig
