无法打开共享对象文件:没有这样的文件或目录

Question

我遇到了火炬群集的头节点上找不到的共享库.我已经构建了库以及指定库的正确路径,同时用g ++编译我自己的程序"荒谬".所以我觉得很奇怪.任何的想法？感谢致敬!

[tim@user1 release]$ make  
...  
...  
g++ -pipe -W -Wall -fopenmp -ggdb3 -O2    -I/home/tim/program_files/ICMCluster/ann_1.1.1/include -I/home/tim/program_files/ICMCluster/libsvm-2.89  -I/home/tim/program_files/ICMCluster/svm_light  -o absurdity  xxxxxx.o  -L/home/tim/program_files/ICMCluster/ann_1.1.1/release/lib -L/home/tim/program_files/ICMCluster/libsvm-2.89/release/lib -L/home/tim/program_files/ICMCluster/svm_light/release/lib -lm -ljpeg -lpng -lz -lANN -lpthread -lsvm -lsvmlight  

[tim@user1 release]$ ./absurdity

[tim@user1 release]$ LD_LIBRARY_PATH= /home/tim/program_files/ICMCluster/svm_light/release/lib:$LD_LIBRARY_PAT    
[tim@user1 release]$ export LD_LIBRARY_PATH 

[tim@user1 release]$ ./absurdity

libsvmlight.a  libsvmlight.so  

Answer 1

从我的答案复制到这里:https://stackoverflow.com/a/9368199/485088

ldconfig以root用户身份运行以更新缓存 - 如果仍然没有帮助,则需要添加文件路径ld.so.conf(只需在自己的行中输入)或者更好,将条目添加到新文件中(更容易删除) )在目录中ld.so.conf.d.

Answer 2

你LD_LIBRARY_PATH的路径不包括libsvmlight.so.

$ export LD_LIBRARY_PATH=/home/tim/program_files/ICMCluster/svm_light/release/lib:$LD_LIBRARY_PATH

Answer 3

sudo ldconfig

ldconfig创建必要的链接并缓存到命令行,文件/etc/ld.so.conf和受信任目录(/ lib和/ usr/lib)中指定的目录中找到的最新共享库.

通常,包管理器会在安装新库时处理此问题,但并非总是如此(特别是在安装库时cmake).

如果输出为空

$ echo $LD_LIBRARY_PATH

请设置默认路径

$ LD_LIBRARY_PATH=/usr/local/lib

Answer 4

在超级计算机上工作时，我在运行时收到此错误：

module load python/3.4.0
screen
python

要解决该错误，我只需在屏幕终端中重新加载模块即可：

module load python/3.4.0
python
