eos在ubuntu上的编译（mongDB出错最简单的解决办法）

编译环境:Ubuntu16.04 LTS

1、cd eos

    ./eosio_build.sh

2、报错

      一、执行eosio_build.sh可能会出现：Your system must have 7 or moreGigabytes of physical memory installed

      修改scripts/eosio_build_ubuntu.sh的代码：

            -       if [ "${MEM_MEG}" -lt 7000 ]; then

+       if [ "${MEM_MEG}" -lt 2000 ]; then

                printf "\\tYour system must have 7 or more Gigabytes of

physical memory installed.\\n"

                printf "\\tExiting now.\\n"

            exit 1

    二、还会出现You must have at least 20GB ofavailable storage to install EOSIO.

修改scripts/eosio_build_ubuntu.sh的代码：

     if [ "${DISK_AVAIL%.*}" -lt "${DISK_MIN}" ]; then

                printf "\\tYou must haveat least %sGB of available storage to install EOSIO.\\n""${DISK_MIN}"

                #printf\\tExiting now.\\n

                #exit 1（直接注释掉这行）

    三、安装MongDB会出现错误

这个你可以在/etc/hosts 修改hosts文件，在文件里加上

thub-production-release-asset-2e65be.s3.amazonaws.com

然后再执行eosio_build.sh
