Obwohl rpath eingestellt ist, wird eine DLL nicht gefunden

Question

ldd kann keine DLL finden, die in der rpath Definition vorhanden ist. Einige andere Bibliotheken werden gefunden (check /./../lib/*)

Hier die Ausgabe von ldd (wir können sehen, dass 2 dll in ../lib gefunden werden, aber nicht libexpat.so.0:

Hier die rpath:

Nun ist die Killer der Tat: Es ist funktioniert mit Klirren 3.8, aber nicht mit 6.3 gcc (ubuntu 16.10)

Offensichtlich ein LD_LIBRARY_PATH Hinzufügen = ../lib machen es funktioniert wieder, aber das Ziel von rpath war zu setzen zu vermeiden es

Jede Idee?

Answer 1

finde ich nur die Erklärung: Klirren setzen in der [ERFORDERLICH] -Abschnitt der elf binären alle Bibliotheken (auch Bibliotheken nicht explizit von mir enthalten, aber durch die referenzierte [erforderlich] Sektion der Bibliothek, die ich

Und eine DLL gehören die fehlende ein libexpat:

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

Dynamic section at offset 0x1e698 contains 29 entries:

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] 

aber RUNPATH nur durch die binäre nicht durch die DLL verwendet wird (das kann, ist selbst RUNPATH haben).

2 Lösungen: - fügen Sie einen RUNPATH in libaprutil-1.so.0 hinzu, um zu erzwingen, Bibliothek von "." - fügen Sie explizit alle fehlenden dll in meinem Build

Ich hoffe, es hilft
