RPATH适用于LDD显示的大多数依赖库，但不适合CentOS 7.7上的所有库。

Question

我仅在CENTOS 7.7上有这个问题（在Fedora 33和35上都可以按预期工作）。由于某种原因，我的适应应用程序试图打开系统libqt5core.so.5，libsystemd.so.0，以及其他一些。

我确保拥有rpath（即，甚至没有runpath：我通过使用patchelf-force-rpath -set-rpath）实现了它。正确设置所有可执行文件和LIB。在下面，我在用-Appimage-track选项中提取它后显示了我的适应性情况，并且应用patchelf set rpath：

但是，但是，我有libqt5core.so.5，在哪里：

[jenya@localhost bin]$ ls /home/jenya/Downloads/squashfs-root/usr/bin/./../lib/libQt5Core.so.5 
/home/jenya/Downloads/squashfs-root/usr/bin/./../lib/libQt5Core.so.5

此外，我确保确实具有rpath的确，而不是Runpath：

[jenya@localhost bin]$ readelf -d ./myapp  | grep PATH
 0x000000000000000f (RPATH)              Library rpath: [$ORIGIN/../lib]

[jenya@localhost bin]$ readelf -d ../lib/libQt5Widgets.so.5  | grep PATH
 0x000000000000000f (RPATH)              Library rpath: [$ORIGIN]

如何这可以是，如何解决？谢谢您的关注。

Answer 1

[jenya@localhost bin]$ objdump -s -j .note.ABI-tag ../lib/libQt5Core.so.5 

../lib/libQt5Core.so.5:     file format elf64-x86-64

Contents of section .note.ABI-tag:
 03a4 04000000 10000000 01000000 474e5500  ............GNU.
 03b4 00000000 03000000 11000000 00000000  ................

如果仔细观察，人们可以看到03 ... 11。这说它希望内核不小于3.17。

strip的解决方案在此处提出 https://bugsarlinux.org.org/任务/61130 在网上的其他地方没有帮助我。

因此，我安装了hexedit，并用它打开了lib。我制作了/ - 的搜索> 10000000000000000474E5500，然后替换11（即17）（IE 17）01（仅一些版本少一些版本比3.10，即CentOS 7.7的版本），并保存和退出（ctrl+x）。

这是一个技巧。
