为什么我的二进制文件找不到 libwx_gtk3u_html-3.2.so.0？

Question

我正在尝试在 Linux 上构建 FileZilla 并运行我的二进制文件，而无需在终端中设置

LD_LIBRARY_PATH

。 我已经得到了当前的目录结构：

FileZilla3
├── bin
│   ├── filezilla
│   ├── fzputtygen
│   ├── fzsftp
│   └── fzstorj
└── lib
    ├── libfilezilla.so.45
    ├── libfzclient-commonui-private-3.67.1.so
    ├── libfzclient-private-3.67.1.so
    ├── libgmp.so.10
    ├── libgnutls.so.30
    ├── libhogweed.so.6
    ├── libnettle.so.8
    ├── libsqlite3.so.0
    ├── libwx_baseu-3.2.so.0
    ├── libwx_baseu_xml-3.2.so.0
    ├── libwx_gtk3u_aui-3.2.so.0
    ├── libwx_gtk3u_core-3.2.so.0
    ├── libwx_gtk3u_html-3.2.so.0
    └── libwx_gtk3u_xrc-3.2.so.0

我已经根据此处列出的内容将适当的库一一放入

lib

中：

$ eu-readelf -d filezilla

Dynamic segment contains 47 entries:

  NEEDED            Shared library: [libc.so.6]
  RUNPATH           Library runpath: [$ORIGIN/../lib]

但是，当我现在尝试运行二进制文件时，我得到以下信息：

$ ./bin/filezilla
./bin/filezilla: error while loading shared libraries: libwx_gtk3u_html-3.2.so.0: cannot open shared object file: No such file or directory

为什么找不到

libwx_gtk3u_html-3.2.so.0

？ 它位于

lib

目录中。 当 ELF 中显然不需要该文件时，为什么它甚至需要该文件？ 可以被另一个SO文件拉入吗？

Answer 1

结果我的库没有在同一目录中寻找所需的库，因为它们没有设置

RUNPATH

。 我必须将其设置为在原始目录中查找，如下所示，然后它们正确加载：

patchelf --set-rpath "\$ORIGIN" ./libwx_gtk3u_xrc-3.2.so.0
