根因分析

动态库（`.so`）不在标准库路径或`LD_LIBRARY_PATH`中。

English

Dynamic library (`.so`) not in standard library paths or `LD_LIBRARY_PATH`.

generic

解决方案

  1. 90% 成功率 Set `LD_LIBRARY_PATH` before running 
    export LD_LIBRARY_PATH=/path/to/lib:$LD_LIBRARY_PATH
./program
  2. 85% 成功率 Use `-rpath` in LDFLAGS with absolute path 
    // #cgo LDFLAGS: -rpath,/path/to/lib -L/path/to/lib -lfoo

无效尝试

常见但无效的做法:

  1. Copying .so to current directory 70% 失败

    Current directory not searched by default.

  2. Using `-rpath` without absolute path 50% 失败

    Relative rpath may break if binary moved.
