使用LD_LIBRARY_PATH时与Anaconda链接的问题（ld_library_path 不起作用）
我只是尝试在Linux 64位上安装Anaconda。一切似乎都运行良好，但是当我尝试从终端启动IPython时，出现以下错误：
$ ipythonTraceback (most recent call last): File "/home/josh/installs/conda/1.7.0/bin/ipython", line 4, in <module> from IPython import start_ipython File "/home/josh/installs/conda/1.7.0/lib/python2.7/site-packages/IPython/__init__.py", line 43, in <module> from .config.loader import Config File "/home/josh/installs/conda/1.7.0/lib/python2.7/site-packages/IPython/config/__init__.py", line 16, in <module> from .application import * File "/home/josh/installs/conda/1.7.0/lib/python2.7/site-packages/IPython/config/application.py", line 27, in <module> from collections import defaultdict File "/home/josh/installs/conda/1.7.0/lib/python2.7/collections.py", line 9, in <module> from operator import itemgetter as _itemgetter, eq as _eqImportError: /home/josh/installs/conda/1.7.0/lib/python2.7/lib-dynload/operator.so: undefined symbol: _PyUnicodeUCS4_AsDefaultEncodedString如果尝试更新conda，则会收到相同的错误：

小编典典在您的系统上，Anaconda正在获取libpython的“系统版本”，它是使用2字节Unicode编译的，而Anaconda是使用4字节Unicode编译的。由于某种原因，这是一种不寻常的情况，指示的operator.so文件的动态加载程序正在使用您的系统libpython库。
另外，无论您使用什么PATH，看起来都在运行python时获得了标准的“系统” Python。
您是否已启动新终端或运行＃source .bashrc？您正在使用哪个Linux发行版？您的环境中是否设置了LD_LIBRARY_PATH？
请注意，还会在https://github.com/ContinuumIO/conda/issues/296上询问此问题，因此可能会有答案。
Android NDK – 未找到库无法链接EXECUTABLE – 如何设置LD_LIBRARY_PATH？
Runtime.getRuntime().exec(myCommand);
并使用以下命令加载所需的共享库：
static {
System.loadLibrary(myLib);
}
但是当运行我的项目并从错误流打印输出时,我收到以下错误：
link_image[1963]: 7520 Could not load needed library ''libmyLib.so'' for ''./myCommand'' (load_library[1105]: Library ''libmyLib.so'' not found)CANNOT LINK EXECUTABLE
我保证libmyLib.so确实存在于libs / armeabi /目录下的项目中,并且它被复制到我的Android设备下的/data/data/myProject.path.package/lib/目录下.可执行文件和库的所有者和组都是系统：系统和权限也是可以的.
在开始时从adb shell执行命令时我得到了相同的错误但是我可以设置LD_LIBRARY_PATH并运行正常：
./adb shell export LD_LIBRARY_PATH=/data/data/myProject.path.package/lib:$LD_LIBRARY_PATH /data/data/myProject.path.package/myCommand
所以问题是,如何从java Android项目中做到这一点？
注意：我在GT-P1010上使用Linux,Eclipse Sequoyah,NDK-r5b,Android 2.3.6(API 10).
解决方法
String[] envp = {"LD_LIBRARY_PATH=/data/data/cse.ecg.dcmtk/lib:$LD_LIBRARY_PATH"};
Runtime.getRuntime().exec(myCommand,envp);
现在的问题是,使用exec()执行的进程无法解析主机名(它来自adb shell;设置了Internet权限).有什么暗示吗？
android – LD_LIBRARY_PATH定义必需的libs
当我在Ubuntu上运行ldd时,它应该给我MyApp所需的lib列表.但是,这是我到目前为止所得到的：
$cd MyAppProjFolder $ldd MyApp | grep libQt ldd: ./MyApp: not regular file $file MyApp MyApp: directory $cd Debug $ldd MyApp | grep libQt ./MyApp: No such file or directory $cd android-build $ldd MyApp | grep libQt ./MyApp: No such file or directory $cd bin $ldd MyApp | grep libQt ./MyApp: No such file or directory
要查找可执行文件的位置,请运行以下命令：
$find /home/user/MyAppProjFolder -name MyApp /MyAppProjFolder/.../bin/classes/org/qtproject/example/MyApp $ldd MyApp | grep libQt ./MyApp: No such file or directory
我在这里错过了什么？生成的可执行文件与定义的项目/应用程序的名称不同？
解决方法
1)您正在尝试在目录或不存在的文件上运行ldd.
2)您似乎在目标二进制文件上从主机运行ldd.它不一定相同.
我的建议是找到你的可执行文件,并确保你运行正确的ldd.
编辑：因为您在初始帖子之后将问题的要点修改到一定程度,所以回复：
What am I missing here?
如何在同一个文件中使用find和ldd.
The executable file generated is different from the name of the defined project/app?
它是您/您在构建系统中定义的内容,因此我们无法知道,特别是如果您不粘贴相关代码.
c – LD_LIBRARY_PATH
我正在调查系统调用失败,所以有什么方法可以设置使用LD_LIBRARY_PATH设置设置正确的路径？
解决方法
让shell脚本导出新的LD_LIBRARY_PATH变量,然后启动您的应用程序
例如(foo是你的应用)
#!/bin/sh LD_LIBRARY_PATH=some_path:$LD_LIBRARY_PATH export LD_LIBRARY_PATH foo
Conda仅将env设置为LD_LIBRARY_PATH
我安装了miniconda3，并在其中创建了一个名为py35的虚拟环境。我有一些我只想在此环境中使用的库。因此他们在
/.../miniconda3/envs/py35/libs但是，由于LD_LIBRARY_PATH不包含上述文件夹，因此无法从环境中找到它们。现在，我想将LD_LIBRARY_PATH设置为仅在虚拟环境中时才包含/
lib。
我当时正在考虑修改miniconda用来启动环境的激活脚本，但是不确定这是标准做法还是有更简单的方法来实现。
答案1
小编典典您可以在环境激活时通过编辑activate.d/env_vars.sh脚本来设置环境变量。参见此处：https : //conda.io/docs/user-
guide/tasks/manage-environments.html#macos-and-
linux
该链接的关键部分是：
在“终端”窗口中找到conda环境的目录，例如
/home/jsmith/anaconda3/envs/analytics。输入该目录并创建以下子目录和文件：
cd /home/jsmith/anaconda3/envs/analyticsmkdir -p ./etc/conda/activate.d
mkdir -p ./etc/conda/deactivate.d
touch ./etc/conda/activate.d/env_vars.sh
touch ./etc/conda/deactivate.d/env_vars.sh编辑
./etc/conda/activate.d/env_vars.sh如下：#!/bin/shexport MY_KEY=’secret-key-value’
export MY_FILE=/path/to/my/file/编辑
./etc/conda/deactivate.d/env_vars.sh如下：#!/bin/shunset MY_KEY
unset MY_FILE运行时
conda activate analytics，环境变量MY_KEY和MY_FILE设置为您写入文件中的值。运行时condadeactivate，这些变量将被擦除。
