加载 boost 共享库时出错
我正在centos上工作。我在我的系统上安装了 boost 版本 1.45.0。程序已正确编译，但每当我键入命令查看输出时，都会出现以下错误：
./a.out：加载共享库时出错： libboost_thread.so.1.45.0：无法打开共享对象文件：没有这样的 文件或目录

除了其他答案之外，您还可以在链接可执行文件时设置
DT_RPATHelf 标记。这样，如果库是，则不必记住设置
LD_LIBRARY_PATH安装在非标准位置。In addition to the other answers, you can also set the
DT_RPATHelf tag when linking your executableThis way you don't have to remember to set your
LD_LIBRARY_PATHif the libraries are installed in a non-standard location.你是如何安装boost库的？
您可能遇到的问题是链接器找不到库，并且当您构建程序时，您必须手动指定其他库路径来搜索库。
您可以做的快速修复是设置
LD_LIBRARY_PATH以包含boost线程库所在的目录：export LD_LIBRARY_PATH=/path/to/boost/libs:$LD_LIBRARY_PATH<代码>./runExecutable
How did you install the boost libraries?
The problem you're likely having is that the linker can not find the libraries, and when you built your program, you had to manually specify additional library paths to search for libraries.
A quick fix you can do is to set
LD_LIBRARY_PATHto include the directory where the boost thread library is:export LD_LIBRARY_PATH=/path/to/boost/libs:$LD_LIBRARY_PATH./runExecutable您需要设置 LD_LIBRARY_PATH 环境变量以包含 Boost 库的路径（它们可能位于 /usr/local/lib 等）。
在 bash 中，这只是
You need to set the
LD_LIBRARY_PATHenvironment variable to include the path to the Boost libraries (they're possibly in/usr/local/lib, etc).In bash, this is simply
