如何在低内存系统上使用RVM编译ruby？ [英] How to compile ruby with RVM on a low memory system?

问题描述

  rvm install 1.9.3 
  

会导致错误在make.log中：

  ... 
编译./enc/trans/emoji_sjis_docomo.c 
编译./enc/trans/emoji_sjis_kddi.c 
 gcc：内部编译器错误：Killed（程序cc1）
 gcc：内部编译器错误：Killed（程序cc1）
 gcc：内部编译器错误：杀死（程序cc1）
请提交完整的错误报告，
和预处理源（如果适用）。 
 ... 
  

dmesg 显示

  [180031.341709] send sigkill to 3705（cc1），adj 0，size 3394 
  

free 显示某个点运行configure过程：

 使用的空闲共享缓冲区总数缓存
 Mem：241668 238676 2992 0 92 2020 
  -  / + buffers / cache：236564 5104 
 Swap：262140 262140 0 
  

所以我假设256MB RAM和256MB Swap不足以编译Ruby

我读过应该可以使用gcc的一些参数，请参阅：
http://hostingfu.com/article/compiling-with-gcc-on-low-memory-vps

但是

  rvm install 1.9.3 --with-CFLAGS = $ CFLAGS --param ggc -min-expand = 0 --param ggc-min-heapsize = 8192
  

不适用将标志赋予gcc，日志对于标志仍然是相同的：

 命令（2）：__rvm_make -j4 
 CC = gcc 
 LD = ld 
 LDSHARED = gcc -shared 
 CFLAGS = -O3 -ggdb -Wall -Wextra -Wno -unused-parameter -Wno-括弧-Wno-long-long -Wno-missing-fiel $ 
 XCFLAGS = -include ruby​​ / config.h -include ruby​​ / missing.h -fvisibility = hidden -DRUBY_EXPORT 
 CPPFLAGS = -I。 -I.ext / include / x86_64-linux -I./include -I。 
 DLDFLAGS = -Wl，-soname，libruby.so.1.9 
 SOLIBS = -lpthread -lrt -ldl -lcrypt -lm 
  

如何在该机器上编译ruby？

解决方案

文件解决了这个问题。这里是步骤：

$ pre $ $ $ $ $ sudo mkdir -p / var / cache / swap /
sudo dd if = / dev / zero of = / var / cache / swap / swap0 bs = 1M count = 512
sudo chmod 0600 / var / cache / swap / swap0
sudo mkswap / var / cache / swap / swap0
sudo swapon / var / cache / swap / swap0

重启后不使用交换文件。它可以集成到 / etc / fstab 中，以便在重新启动后使用它：

  / var / cache / swap / swap0 none swap sw 0 0 
  

以上步骤创建一个我在这里找到的交换文件（德文）： http://wiki.ubuntuusers.de/Swap#Swap-als -Datei - 上述内容的许可： http://creativecommons.org /licenses/by-nc-sa/2.0/de/deed.en （署名 - 非商业性使用 - 相同方式2.0德国（CC BY-NC-SA 2.0 DE））

rvm install 1.9.3

leads to the error in the make.log:

...
compiling ./enc/trans/emoji_sjis_docomo.c
compiling ./enc/trans/emoji_sjis_kddi.c
gcc: internal compiler error: Killed (program cc1)
gcc: internal compiler error: Killed (program cc1)
gcc: internal compiler error: Killed (program cc1)
Please submit a full bug report,
with preprocessed source if appropriate.
...

dmesg shows

[180031.341709] send sigkill to 3705 (cc1), adj 0, size 3394

free shows at some point running configure process:

             total       used       free     shared    buffers     cached
Mem:        241668     238676       2992          0         92       2020
-/+ buffers/cache:     236564       5104
Swap:       262140     262140          0

So I assume that 256MB RAM and 256MB Swap is not enough to compile Ruby on it.

I read that it should be possible using some parameters for gcc, see: http://hostingfu.com/article/compiling-with-gcc-on-low-memory-vps

But

  rvm install 1.9.3 --with-CFLAGS="$CFLAGS --param ggc-min-expand=0 --param ggc-min-heapsize=8192"

Does not work to give the flags to gcc, log is still the same for the flags:

command(2): __rvm_make -j4
        CC = gcc
        LD = ld
        LDSHARED = gcc -shared
        CFLAGS = -O3 -ggdb -Wall -Wextra -Wno-unused-parameter -Wno-parentheses -Wno-long-long -Wno-missing-fiel$
        XCFLAGS = -include ruby/config.h -include ruby/missing.h -fvisibility=hidden -DRUBY_EXPORT
        CPPFLAGS =   -I. -I.ext/include/x86_64-linux -I./include -I.
        DLDFLAGS = -Wl,-soname,libruby.so.1.9
        SOLIBS = -lpthread -lrt -ldl -lcrypt -lm

How to compile ruby on that machine?

解决方案

Creating a 512MB swap-file solved the problem. Here are the steps:

sudo mkdir -p /var/cache/swap/
sudo dd if=/dev/zero of=/var/cache/swap/swap0 bs=1M count=512
sudo chmod 0600 /var/cache/swap/swap0
sudo mkswap /var/cache/swap/swap0 
sudo swapon /var/cache/swap/swap0

The swap file is not used after a restart. It can be integrated in /etc/fstab to use it after restart:

 /var/cache/swap/swap0    none    swap    sw      0 0

The above steps to create a swap-file I found here (in German): http://wiki.ubuntuusers.de/Swap#Swap-als-Datei - licence for the above content: http://creativecommons.org/licenses/by-nc-sa/2.0/de/deed.en (Attribution-NonCommercial-ShareAlike 2.0 Germany (CC BY-NC-SA 2.0 DE))
