我正在编译Yak的源代码。（来自论文[OSDI '16]：Yak：一个高性能的大数据友好垃圾收集器）Yak基于OpenJDK 1.8，它对GC算法有一些改变。但是，当我使用命令'bash configure'和'make all'构建一个版本j2sdk-image供使用时，我发现存在问题。当我运行'j2sdk-image / bin / javac xxx.java'时，java文件是一个像HelloWorld这样的简单类。但是，我遇到了一个问题：
zmx@ubuntu:~/nju/yak-openjdk8/my_testcases$ ../build/linux-x86_64-normal-server-release/images/j2sdk-image/bin/javac TestMonotask.java
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 268435472 bytes for Chunk::new
# An error report file with more information is saved as:

[thread 139717465741056 also had an error]
我在运行javac时出现内存问题？这太可怕了。错误日志在这里。
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 268435472 bytes for Chunk::new
# Possible reasons:
# The system is out of physical RAM or swap space
# In 32 bit mode, the process size limit was hit
# Possible solutions:
# Reduce memory load on the system
# Increase physical memory or swap space
# Check if swap backing store is full
# Use 64 bit Java on a 64 bit OS
# Decrease Java heap size (-Xmx/-Xms)
# Decrease number of Java threads
# Decrease Java thread stack sizes (-Xss)
# Set larger code cache with -XX:ReservedCodeCacheSize=
# This output file may be truncated or incomplete.
#
# Out of Memory Error (allocation.cpp:388), pid=40203, tid=139717464688384

我的Ubuntu上有3g内存。当我运行javac时，我发现内存从600m上升到3g，然后javac（javac !!而不是java）进程被杀死。我想知道问题出在哪里。希望可以有人帮帮我。谢谢！
问题是我使用的环境与Yak的作者不同。这是正确的环境。当我使用正确的环境时，问题就解决了。
