c - ld.so 无法加载所需的库

Question

我们使用具有库路径详细信息(使用 -L 选项编译)的 makefile 创建了我们模块的可执行文件。所有必需的库都存在于该路径中，并且它被设置为 LD_LIBRARY_PATH 环境变量。但我仍然得到在 dbx 中运行可执行文件时出现以下错误。

  dbx MsgServer
  For information about new features see `help changes'
  To remove this message, put `dbxenv suppress_startup_message 7.2' in your .dbxrc
  Reading MsgServer
  Reading ld.so.1
  ld.so.1: MsgServer: fatal: libcp.so: open
  failed:       No such file or directory
  terminating signal 9 SIGKILL

我无法弄清楚为什么库没有链接。这是 ldd 的输出。

    ldd MsgServer
    libcp.so =>      (file not found)
    libftux.so =>    (file not found)

如有任何帮助，我们将不胜感激。

你的 LD_LIBRARY_PATH 导出了吗？您需要将其导出。
