Question

I ve just stumbled on some weird behavior: before I launch my application I ve set the LD_LIBRARY_PATH to some local lib directory which contains all needed libs. After launch I have part(the most part) libs are loaded from the LD_LIBRARY_PATH but a few are loaded from the standard /usr/lib(e.g /usr/lib/libQtNetwork.so.4, /usr/lib/libSM.so.6). All those libs are contained in the directory which is listed in the LD_LIBRARY_PATH. Could anyone explain why do I have such behavior? I m not very familiar with a Linux world but this article says that my approach should work

P.S. If I rename /usr/libs to something other I ll have my application running with all libs used from my libs location

事先感谢!

我找到答案,答案是RPATH。所有Qt图书馆都是用RPATH=$QT_INSTALL_DIR建造的,因此,如果你想在短链氯化石蜡中制造“bundle”,就应当拆除RPATH。 <>RPATH可通过援引tchrpath 的指令予以删除。感谢大家提供帮助!

奥基似乎你正在使用Qt,但同样的原则适用,并不具体。

首先要看的是:PATH,环境变量,当时的QTDIR, 然后是LD_LIBRaire_PATH/strong>。

Normally you do not need to "play" with LD_LIBRARY_PATH. If your PATH is correct then you should be fine.

作为附带说明(可能知道): 看到你使用的图书馆能够使用ldd的指挥。例如:

user@host:~/$ ldd $QTDIR/bin/qmake linux-vdso.so.1 => (0x00007fff169ff000) libstdc++.so.6 => /usr/lib/libstdc++.so.6 (0x00007fb6bf63e000) libm.so.6 => /lib/libm.so.6 (0x00007fb6bf3bb000) libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x00007fb6bf1a3000) libc.so.6 => /lib/libc.so.6 (0x00007fb6bee20000) /lib64/ld-linux-x86-64.so.2 (0x00007fb6bf97e000)

假定您的<>QTDIR enverras。如果安装的气球分布将步入正轨,请携带QT。如果您确实安装或编辑了一种习俗,那么你就需要铺路。

Good luck.
