FISCO BCOS 源码编译文档：https://fisco-bcos-documentation.readthedocs.io/zh_CN/latest/docs/tutorial/compile.html

使用64位操作系统 ​

操作系统需要是64位的。因为FISCO-BCOS does not support compiling on 32-bit systems。

具体原因是rocksdb不再支持32位操作系统，具体代码如下：

cpp
// Get the value of tokutime for right now.  We want this to be fast, so we
// expose the implementation as RDTSC.
static inline tokutime_t toku_time_now(void) {
#if defined(__x86_64__) || defined(__i386__)
  uint32_t lo, hi;
  __asm__ __volatile__("rdtsc" : "=a"(lo), "=d"(hi));
  return (uint64_t)hi << 32 | lo;
#elif defined(__aarch64__)
  uint64_t result;
  __asm __volatile__("mrs %[rt], cntvct_el0" : [ rt ] "=r"(result));
  return result;
#elif defined(__powerpc__)
  return __ppc_get_timebase();
#elif defined(__s390x__)
  uint64_t result;
  asm volatile("stckf %0" : "=Q"(result) : : "cc");
  return result;
#else
#error No timer implementation for this platform // 32位系统会在这里报错
#endif
}

FISCO BCOS使用的是rocksdb_6.29.3版本，而根据RocksDB 6.22.1 fails to build on ARM · Issue #8609 · facebook/rocksdb说提到的，rocksdb_6.15版本依然可以在arm32位系统上构建。

cmake版本高于3.20 ​

编译需要cmake 3.20以上，所以需要手动编译安装cmake

bash
tar zxvf cmake-3.26.3.tar.gz

cd cmake-3.26.3
./configure
make -j $(nproc)
sudo make install

安装依赖包 ​

bash
sudo apt install -y g++ libssl-dev openssl cmake git build-essential autoconf texinfo flex patch bison libgmp-dev zlib1g-dev automake libtool

上面命令是官方文档给出的依赖包，安装完这些包之后，还需要安装snappy库：

bash
sudo apt install libsnappy-dev

否则节点启动时无法连接到rocksdb。

编译 ​

拉取代码：

bash
git clone https://github.com/FISCO-BCOS/FISCO-BCOS.git 

cd FISCO-BCOS

git checkout release-2.10.0

编译：

bash
mkdir -p build && cd build

cmake -DARCH_NATIVE=on ..

make -j $(nproc)

编译配置 ​

bash
root@raspberrypi:~/FISCO-BCOS/build# cmake -DARCH_NATIVE=on ..

rocksdb启动失败 ​

如果启动bcos失败，日志报错如下：

bash

是因为没有安装snappy库，执行sudo apt install libsnappy-dev安装后重新编译librocksdb.a文件即可。
