我正在尝试安装 boost148 软件包。这是与我已安装的 boost 不同的包，版本为 1.41。

yum install boost
Loaded plugins: refresh-packagekit, security
Setting up Install Process
Package boost-1.41.0-18.el6.x86_64 already installed and latest version
Nothing to do

但是当我尝试使用安装 Boost148 时，yum install boost148 -y我收到以下信息

Transaction Check Error:
  file /usr/lib64/libboost_chrono-mt.so.1.48.0 from install of boost148-chrono-1.48.0-7.el6.x86_64 conflicts with file from package boost-chrono-1.48.0-14.el6.x86_64

所以我检查了boost148是否部分安装

yum list installed | grep boost148

什么都没有出现。

此外，如果我尝试 ls 事务检查错误中的任何文件，它们都不存在。

# ls /usr/lib64/libboost_chrono-mt.so.1.48.0
ls: cannot access /usr/lib64/libboost_chrono-mt.so.1.48.0: No such file or directory

我认为这是某种类型的 yum 数据库问题，所以我做了 ayum-complete-transaction和 ayum clean all但我仍然无法安装 boost145 软件包。关于如何说服 yum 继续安装的任何想法？

当我运行名为“myfile”的用户应用程序之一时。 

$ ./myfile

我收到以下输出

bash: ./myfile: cannot execute binary file

我的用户希望二进制文件能够运行。我认为这是一个编译错误，但无法确认。我运行了文件命令

$ file myfile
myfile: ELF 64-bit LSB relocatable, x86-64, version 1 (SYSV), not stripped

我的 RHEL6 操作系统是 64 位的

$ uname -p -o
x86_64 GNU/Linux

所以在我看来，它是为正确的架构而设计的。我不明白文件命令输出中的“可重定位”是什么意思，也无法从手册页中得到解释。

为了更好地衡量，我检查了共享库依赖项

$ ldd myfile 
not a dynamic executable

有什么方法可以让这个文件运行，或者给我的用户一些关于它为什么不能运行的建设性信息（比如他需要使用 x 重新编译）？

追踪

execve("./myfile", ["./myfile"], [/* 22 vars */]) = -1 ENOEXEC (Exec format error)
