本文主要是介绍RP-PX30平台 编译脚本，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
RP-PX30平台编译和原始的原厂编译还是有点不一样的，贴上make.sh
#!/bin/bash
MAKE_THEARD=`cat /proc/cpuinfo | grep "processor" | wc -l` #获得主机CPU线程数量
MAKE_TOTAL=`cat /proc/meminfo | grep "MemTotal" | tr -cd "[0-9]"` #获得内存大小 按KB 算
MAKE_MEM=` expr $MAKE_TOTAL / 1048576` #内存字节数除以1048576 获得多少个G 的内存
#echo $MAKE_MEM
jvm_set_mem()# jvm 设置内存函数 设置 JACK_SERVER_VM_ARGUMENTS 并给出警告，小于8G内存不能编译
{
if [ $MAKE_MEM -gt 32 ] #如果内存大于32G
then
{
export JACK_SERVER_VM_ARGUMENTS="-Dfile.encoding=UTF-8 -XX:+TieredCompilation -Xmx32768m"
