（这个问题是我的间接延续上一个问题已经解决了。）
我正在尝试做的事情的小总结
我有一个名为的 .so 文件pin_sim.so以建筑模拟器 snipersim 命名的 .so 文件（http://www.snipersim.org）。该库基本上实现了模拟所使用的英特尔 PIN 仪器库的包装器。
该文件在主应用程序开始模拟之前动态加载。由于仿真目标可执行文件必须加载与 相同的库版本pin_sim.so，并且pin_sim.so打包了某些版本的库，因此在仿真开始之前，它会使用 来检查 pin_sim.so 加载了哪个版本的库ldd。
问题
在我的家庭桌面（运行 Linux Mint 17.2）上，它可以正常工作。ldd pin_sim.so返回：
linux-vdso.so.1 => (0x00007ffcd75a3000)
libpython2.7.so.1.0 => /usr/lib/x86_64-linux-gnu/libpython2.7.so.1.0 (0x00007fdd19d08000)

libutil.so.1 => /lib/x86_64-linux-gnu/libutil.so.1 (0x00007fdd18421000)
然而，在我有权访问的运行 OpenSUSE 13.1 的计算集群上，此命令返回（无论我复制文件还是重新编译它）：
not a dynamic executable
此外，我无法正确运行 sniper（模拟永远不会执行，我认为这与 pin_sim.so 未正确加载有关）。
如果我在集群中编译该文件，然后复制到我的家用计算机，ldd 会像以前一样正常工作。我尝试过 ldd 的所有其他文件（甚至是主狙击手二进制文件）都可以正常工作，只有 pin_sim.so 失败。

我尝试过的/我的想法
我对linux动态链接过程不是很熟悉，所以没怎么尝试。
我环顾网络，只能找到对非常旧的二进制文件（在 ldd 支持添加到 ELF 格式之前编译的） ldd 的引用，或者在没有 64 位系统下在 32 位二进制文件上运行 ldd 的引用。已安装 32 位系统库。由于这个二进制文件是我编译的，并且是 64 位的，所以我不知道为什么 ldd 可能会失败。
我正在考虑将 sniper 中的版本检查器从使用 ldd 切换为使用 readelf/objdump，但我仍然对 ldd 失败感到惊讶。
有任何想法吗？我在集群中没有 root 访问权限。
编辑1：斯特雷斯
我在集群机器上进行了两次系统调用跟踪。一个在 sniper 二进制文件上（其中 ldd 成功），一个在 pin_sim.so 二进制文件上（其中 ldd 失败）。
我切断了开头，直到他们开始分歧的有趣部分。

答案1
在第二个 strace 部分中，有关 x32 二进制文件的描述很奇怪，但不太可能：
faccessat(AT_FDCWD, "/libx32/ld-linux-x32.so.2", X_OK) = -1 ENOENT (No such file or directory)
也许集群的 /lib64/ld-linux-x86-64.so.2 不喜欢你的 pin_sim.so 。
要进一步解决该问题，请尝试/lib64/ld-linux-x86-64.so.2 --list /path/to/your/pin_sim.so在集群上运行。
下次，不要忘记添加-fstrace 参数，它会打开完整的进程树跟踪。
