EOS编译（环境Centos7.4）

首先从github上拉eos的源码
git clone https://github.com/eosio/eos --recursive
如果没加--recursive，则拉完源码后需要在源码目录执行以下命令（如果没有执行，执行编译命令时会提示）
git submodule update --init --recursive
执行编译命令
sh eosio_build.sh
编译完成后

如果顺利，则编译完成。在我的实践中，估计是因为网络的原因（墙），需要做一些操作。

1） 下载mongodb的时候，需要将下载地址替换掉，在文件script/eosio_build_centos.sh
#STATUS=$(curl -LO -w '%{http_code}' --connect-timeout 30
https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-3.6.3.tgz) STATUS=$(curl
-LO -w '%{http_code}' --connect-timeout 30
http://downloads.mongodb.org/linux/mongodb-linux-x86_64-3.6.3.tgz)
2)手动下载mongo-c-driver-1.9.3.tar.gz，放到指定目录，然后在脚本中注释掉下载命令，改为拷贝命令

# STATUS=$(curl -LO -w '%{http_code}' --connect-timeout 30 \ #
"https://github.com/mongodb/mongo-c-driver/releases/download/1.9.3/mongo-c-driver-1.9.3.tar.gz"
) # if [ "${STATUS}" -ne 200 ]; then # rm -f
"${TEMP_DIR}/mongo-c-driver-1.9.3.tar.gz" # printf "\\tUnable to download
MongoDB C driver at this time.\\n" # printf "\\tExiting now.\\n\\n" # exit 1; #
fi cp /opt/eos/scripts/mongo-c-driver-1.9.3.tar.gz ${TEMP_DIR}/
3）之前安装了tcmaloc，但是没有配置链接
[root@localhost eos]# build/programs/nodeos/nodeos
build/programs/nodeos/nodeos: error while loading shared libraries:
libtcmalloc.so.4: cannot open shared object file: No such file or directory
解决方案：
[root@localhost gperftools-master]# echo /usr/local/lib >
/etc/ld.so.conf.d/libtcmalloc.conf [root@localhost gperftools-master]# ldconfig
