The compilation depends on SPDK (as git submodule in third_party/spdk), DPDK, and optionally FIO for plugin support, with the versions spdk-25.05, dpdk-22.11, and fio-3.39 used respectively.

The spdk.patch must be applied during SPDK compilation, and C++17 compiler support is required.

Assuming all projects are located in /chenxu14/workspace

First, initialize the SPDK submodule:

git submodule update --init

# Basic build (automatically compiles SPDK and builds without FIO plugin)
./compile.sh

# Build with FIO plugin support (automatically downloads and compiles FIO)
./compile.sh --enable-fio-plugin

# Build without automatically compiling SPDK (assuming SPDK is already built)
./compile.sh --disable-spdk-build

# Build with custom FIO version
./compile.sh --enable-fio-plugin --fio-version fio-3.39

# Manual CMake configuration
mkdir build && cd build
cmake .. -DENABLE_FIO_PLUGIN=ON -DBUILD_SPDK=ON -DBUILD_FIO=ON
make -j$(nproc)
