设置用于在运行时加载共享库的LD

我有一个共享对象保存在`pwd` / lib，而使用它的可执行文件成功编译（通过使用-l和-L开关），在运行时它给我的悲伤。如果我尝试运行 LD_LIBRARY_PATH = / my / absolute / path / to / library / directory ./test 它工作正常。但是如果我导出LD_LIBRARY_PATH = / my / absolute / path /到/ library /目录，并且执行 ./ test ，它表示它找不到共享库。但是，如果我执行 LD_LIBRARY_PATH = $ LD_LIBRARY_PATH ./test 再次它工作正常！关于我做错什么的任何想法？

第二个问题与导出LD_LIBRARY_PATH env变量有关。如果我打开一个终端，输入导出LD_LIBRARY_PATH = / path / to / stuff 然后键入 echo $ LD_LIBRARY_PATH 变量是正确的。但是，如果我写一个包含导出命令的脚本，只需运行它就不会更新变量，而是需要运行 source install.sh ，以便实际保持变量。这是最好的解决方案？

I have a shared object saved in `pwd`/lib and while the executable that uses it compiles successfully (by using -l and -L switches), at runtime, it's giving me grief. If I try to run LD_LIBRARY_PATH=/my/absolute/path/to/library/directory ./test it works fine. But if I export LD_LIBRARY_PATH=/my/absolute/path/to/library/directory and do ./test it says that it can't find the shared library. However, if I do LD_LIBRARY_PATH=$LD_LIBRARY_PATH ./test again it works fine!! Any ideas on what I'm doing wrong?

Second issue is related to the exporting of the LD_LIBRARY_PATH env variable. If I open a terminal and type export LD_LIBRARY_PATH=/path/to/stuff and then type echo $LD_LIBRARY_PATH, the variable is correct. However if I write a script containing the export command, simply running it doesn't update the variable, instead I need to run source install.sh in order to actually persist the variable. What's the best solution for this?
