將Makefile轉換為CMakeLists； 無法加載共享庫

[英]Translate Makefile into CMakeLists; Cannot load shared library

 原文  2018-04-09 14:10:26  7   1    c++/ makefile/ cmake/ shared-libraries

問題描述

我有自己的C ++庫，並且正在更改其構建方式（從基本的Makefile過渡到CMake）。

我也有一些利用該庫的C ++示例。

如果我使用Makefile構建庫，則示例運行良好。 如果我使用CMake生成的Makefile進行構建，則該庫似乎可以很好地構建，但是示例error while loading shared libraries: libfpthread.so: cannot open shared object file: No such file or directory將失敗，並error while loading shared libraries: libfpthread.so: cannot open shared object file: No such file or directory 。

用CMake構建

請注意：

  • 這是我第一次使用CMake，而且我對Makefiles不太了解。 贊賞任何形式的建設性意見，即使與問題本身沒有直接關系:-)
  • 對不起，標題太糟糕了； 不知道該怎么稱呼！

我想我了解您的問題，並且有潛在的解決方案。 嘗試將其添加到您的CMakeLists.txt： 

set_property(TARGET fpthread PROPERTY NO_SONAME ON)

並重建libfpthread.so 。

發生這種情況的原因是：

當可執行文件與具有DT_SONAME字段的共享庫鏈接時，運行可執行文件時，動態鏈接程序將嘗試加載DT_SONAME字段指定的共享庫，而不是使用給鏈接器指定的文件名。

摘錄自-soname選項文檔下的https://linux.die.net/man/1/x86_64-linux-gnu-ld.bfd 。
