Trouble in Setting Java Environment Path on Ubuntu (libjvm.so: cannot open shared object file: No such file or directory)
提问by online.0227
Found the solution!
找到了解决办法！
Ubuntu by default ignore the command "RD_LIBRARY_PATH" therefore I need to add those codes in ".bashrc" instead of "/etc/environment" or .profile.
Ubuntu 默认忽略命令“RD_LIBRARY_PATH”，因此我需要在“.bashrc”而不是“/etc/environment”或.profile中添加这些代码。
it now work perfectly fine!
它现在工作得很好！
I am trying to run a program that reads Java method from C/C++ code. (I made it on Windows successfully, now, I am working on Linux)
我正在尝试运行一个从 C/C++ 代码读取 Java 方法的程序。（我在 Windows 上成功完成，现在，我在 Linux 上工作）
I made it successfully compiled and run on Ubuntu, however, the problem is.. Whenever I try to run the program, I have to type following commands on terminal..
我使它成功编译并在 Ubuntu 上运行，但是，问题是.. 每当我尝试运行该程序时，我必须在终端上键入以下命令..
source /etc/environment
./invoke #program name is invoke
If I do not type "source /etc/environment" every time I boot my PC, the error message I get is...
如果我每次启动 PC 时都没有输入“source /etc/environment”，我得到的错误消息是...
error while loading shared libraries: libjvm.so: cannot open shared object file: No such file or directory
Ok. Here is what I added in /etc/environment
好的。这是我在 /etc/environment 中添加的内容
export PATH="$PATH:/usr/lib/jvm/jdk1.7.0_25_x64/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_25_x64
export LD_LIBRARY_PATH=$JAVA_HOME/jre/lib/amd64:$JAVA_HOME/jre/lib/amd64/server
What I want is that, as you know, I want to run the program without typing "source /etc/environment". I also tried typing those PATHs on /etc/profile, but result was same... I should type "source /etc/profile" every time I reboot my PC..
我想要的是，如您所知，我想在不键入“source /etc/environment”的情况下运行该程序。我也尝试在 /etc/profile 上输入这些路径，但结果是一样的......每次我重新启动我的电脑时我都应该输入“source /etc/profile”。
How to make it permanently applied to whole range of System without typing "source /etc/environment" stuffs everytime I boot?
如何使其永久应用于整个系统范围而无需在每次启动时输入“源/等/环境”内容？
if you need to see source code of the program, here is downloadable address: http://cfile237.uf.daum.net/attach/247819495212DF1C07B9EB

Put "-Djava.library.path=FULL_PATH_HERE/jre/lib/amd64" as a JVM option in your C code.
将“-Djava.library.path=FULL_PATH_HERE/jre/lib/amd64”作为C 代码中的JVM 选项。
Edit the full_path_here part.
编辑 full_path_here 部分。
The path is allowed to be relative, but I don't think you can use $JAVA_HOME as a placeholder for the environment variable.
允许路径是相对的，但我认为您不能使用 $JAVA_HOME 作为环境变量的占位符。

I had the same problem of setting the path(permanently) however I was using Red Hat, If you look change PATH permanently on Ubuntuit might help you. There was a file on Red Hat .profilethat once you add your exports statements, they will get loaded when the computer starts. :) There should be the kind of file for ubuntu
我在设置路径（永久）时遇到了同样的问题，但是我使用的是 Red Hat，如果您在 Ubuntu 上永久更改 PATH可能会对您有所帮助。Red Hat .profile上有一个文件，一旦您添加了导出语句，它们就会在计算机启动时加载。:) 应该有 ubuntu 的那种文件
export PATH="$PATH:/usr/lib/jvm/jdk1.7.0_25_x64/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games"
export JAVA_HOME=/usr/lib/jvm/jdk1.7.0_25_x64
导出 JAVA_HOME=/usr/lib/jvm/jdk1.7.0_25_x64

This worked for me:
这对我有用：
For x86:
对于 x86：
export LD_LIBRARY_PATH=/usr/lib/jvm/default-java/jre/lib/i386:/usr/lib/jvm/default-java/jre/lib/i386/server
For x86_64
对于 x86_64
export LD_LIBRARY_PATH=/usr/lib/jvm/default-java/jre/lib/amd64:/usr/lib/jvm/default-java/jre/lib/amd64/server

- add the path of the missing libraries in the file /etc/ld.so.conf
- execute the following command: ldconfig this way, you'll add the new libraries to the default ones.
- To check whether the new libraries have been linked, execute the following command: ldconfig -p to have the list of libraries currently linked by default.
- 在文件 /etc/ld.so.conf 中添加缺失库的路径
- 执行以下命令： ldconfig 这样，您就会将新库添加到默认库中。
- 要检查新库是否已链接，请执行以下命令：ldconfig -p 以默认情况下获得当前链接的库列表。
