尽管设置了rpath，但找不到一个dll

Question

ldd无法找到一个dll，它出现在rpath定义中。找到一些其他库（检查/./../lib/*）

这里是ldd的输出（我们可以看到2个DLL在../lib中找到，但没有找到libexpat.so.0：

这里将rpath：

现在凶手的事实：这是铿锵3.8的作品，但失败GCC 6.3（Ubuntu的16.10）

显然添加LD_LIBRARY_PATH = ../lib目录使其再次工作，但rpath中的目标是避免将其设置

任何想法？

我只是找到了解释：铛放在小精灵二进制文件的[需要的]部分中的所有库（甚至图书馆没有明确地由包括我自己，而是通过引用[需要的]

从铛：我包括从GCC

0x000000000000001d (RUNPATH)   Library runpath: [${ORIGIN}/../lib/:$ORIGIN/../lib/:../lib/] 

而且一个DLL包括缺少一个的libexpat：

readelf -d ../lib/libaprutil-1.so.0 

Dynamic section at offset 0x1e698 contains 29 entries: 
    Tag  Type       Name/Value 
0x0000000000000001 (NEEDED)    Shared library: **[libexpat.so.0]** 
0x0000000000000001 (NEEDED)    Shared library: [libapr-1.so.0] 
0x0000000000000001 (NEEDED)    Shared library: [libuuid.so.1] 
0x0000000000000001 (NEEDED)    Shared library: [librt.so.1] 
0x0000000000000001 (NEEDED)    Shared library: [libcrypt.so.1] 
0x0000000000000001 (NEEDED)    Shared library: [libpthread.so.0] 
0x0000000000000001 (NEEDED)    Shared library: [libdl.so.2] 
0x0000000000000001 (NEEDED)    Shared library: [libc.so.6] 
0x000000000000000e (SONAME)    Library soname: [libaprutil-1.so.0] 

但RUNPATH仅由二进制不是由DLL（即可以拥有自己的是太RUNPATH）。

2解决方案： - 在libaprutil-1.so.0中添加一个RUNPATH以强制从“。”包含库。 - 明确添加我构建中的所有缺少的dll

希望它有帮助
