本文介绍了解决在Linux系统中因SELinux配置不当导致的cannot restore segment prot after reloc: Permission denied错误的方法。该问题通常出现在启动特定应用程序时，并提供两种解决方案：一是禁用SELinux；二是调整SELinux配置。

I run dump_torrent, it reports:

ERROR MESSAGE: ./dump_torrent: error while loading shared libraries: /home/sonic/ws/libtorrent-rasterbar-0.14.5/bin/gcc-4.1.2/release/boost-source/threading-multi/libtorrent.so: cannot restore segment prot after reloc: Permission denied

===============================================

Title
--------
Error: cannot restore segment prot after reloc: Permission denied.

Cause
------
Some Linux distributions with SELinux enabled may prevent IDL from running under the default security context. This TechTip is a workaround for CR#41937

Solution
----------
Newer Linux distributions have enabled new kernel security extensions from the SELinux project at the NSA. These extensions allow finer-grained control over system security. However, SELinux also changes some default system behaviors, such as shared library loading, that can be problematic to third party programs.

If you receive the error message "cannot restore segment prot after reloc: Permission denied" when launching IDL, then your SELinux configuration is preventing IDL from launching.
To rectify this issue, you can either:

* Disabling SELinux altogether by setting the line

SELINUX=disabled

in your /etc/sysconfig/selinux file.

For more information about SELinux, please consult your Linux distribution vendor.
