Eclipse CDT/CSFML，加载共享库时出错

Question

我使用 Kubuntu 14.04、Eclipse CDT 并且喜欢包含生成此错误的 CSFML：

/home/u123/Prog/Test/Debug/Test: error while loading shared libraries: libcsfml-audio.so.2.2: cannot open shared object file: No such file or directory

我的编译器设置：

-DCSFML_STATIC -I/home/u123/Prog/CSFML-2.2/include -O0 -g3 -Wall -c -fmessage-length=0

我的链接器设置

 -L/home/u123/Prog/CSFML-2.2/lib -L/usr/local/lib -Xlinker -rpath /home/u123/Prog/SFML-2.2/lib

ldconfig -v 的一些输出

 /home/u123/Prog/CSFML-2.2/lib:
    libcsfml-system.so.2.2 -> libcsfml-system.so.2.2.0
    libcsfml-graphics.so.2.2 -> libcsfml-graphics.so.2.2.0
    libcsfml-window.so.2.2 -> libcsfml-window.so.2.2.0
    libcsfml-audio.so.2.2 -> libcsfml-audio.so.2.2.0

u123@PC-Ubuntu:~$ ls /home/u123/Prog/CSFML-2.2/lib
libcsfml-audio.so        libcsfml-graphics.so        libcsfml-network.so        libcsfml-system.so        libcsfml-window.so
libcsfml-audio.so.2.2    libcsfml-graphics.so.2.2    libcsfml-network.so.2.2    libcsfml-system.so.2.2    libcsfml-window.so.2.2

u123@PC-Ubuntu:~$ ls /home/u123/Prog/SFML-2.2/lib
libsfml-audio.so        libsfml-graphics.so.2.2.0  libsfml-system.so                 libsfml-window.so.2.2.0

libsfml-graphics.so     libsfml-network.so.2.2.0   libsfml-window.so

ldd:

u123@PC-Ubuntu:~$ ldd /home/u123/Prog/Test/Debug/Test
    linux-vdso.so.1 =>  (0x00007ffec7bfe000)

    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f22631c6000)

    /lib64/ld-linux-x86-64.so.2 (0x000055fd8c8fb000)
    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f22629a3000)

在我看来（但我对 SFML 不是很有经验）CSFML 是 c 中的代码，就像一个门面，它引用了 SFML c++ 代码。

对问题所在有任何想法吗？谢谢。

Answer 1

您的 rpath 选项有错字，

-rpath /home/u123/Prog/SFML-2.2/lib 应该是 -rpath /home/u123/Prog/CSFML-2.2/lib ?
此外，尝试将 -lcsfml-audio 添加到链接器。

Answer 2

设置环境变量LD_LIBRARY_PATH解决了问题。前往

Project->Properties->C/C++ Build->Enviroment, and add a new variable named LD_LIBRARY_PATH, value = /path/to/lib

在这种情况下 /home/u123/Progs/SFML-2.2/lib
