在集群上加载库 [英] loading library on cluster

问题描述

我在这里拥有的集群上通过boost成功地用c ++编译了一个程序.我需要运行SGE脚本来运行仿真.我得到的错误是这个

I successfully compiled a program in c++, with boost, on a cluster we have here. I need to run an SGE script to run the simulation. The error I get is this

./main:加载共享时出错 库:libboost_thread.so.1.45.0: 无法打开共享对象文件:否 这样的文件或目录

./main: error while loading shared libraries: libboost_thread.so.1.45.0: cannot open shared object file: No such file or directory

启动程序时是否需要指定库的名称?我使用的脚本如下

Do I need to specify the name of the library when I launch the program? The script I used is below

#!/bin/sh
# (c) 2008 Sun Microsystems, Inc. All rights reserved. Use is subject to license terms.
# This is a simple example of a SGE batch script

# request Bourne shell as shell for job
#$ -S /bin/sh

#$ -N cr_number       # this name shows in qstat
#$ -S /bin/bash      # run with this shell
#$ -l h_rt=50:00:00  # need 50 hour runtime
#$ -pe mpich 4       # define parallel env
#$ -cwd     # run the job in the directory specified.
#$ -o cr_number.out
#$ -e cr_number.err
# (-j will merge stdout and stderr)

#$ -notify
#$ -M [e-mail] - send mail about this job to the given email address.
#$ -m beas          # send a mail to owner when the job
#                       begins (b), ends (e), aborted (a),
#                       and suspended(s).         and suspended(s).

./main

谢谢

推荐答案

最简单的选择是编译静态二进制文件. (对于gcc，请使用-static.对于其他编译器，请使用RTFM.)

The easiest option is to compile a static binary. (With gcc, use -static. For other compilers, RTFM.)

另一个选择是将LD_LIBRARY_PATH环境变量设置为作业脚本中包含Boost库的目录:

Another option is to set the LD_LIBRARY_PATH environment variable to the directory containing the Boost libraries, inside the job script:

LD_LIBRARY_PATH=/where/ever/you/installed/boost

如果您自己没有安装Boost，则可以使用ldd main找出程序在哪里寻找其库.

If you didn't install Boost yourself, you can find out where your program is looking for its libraries with ldd main.
