安装MPICH2无法填充libmpi.so.1（已卸载openmpi）

我使用以下方式安装了mpich2：

./configure --prefix=/usr/mpich2-install --enable-threads --enable-shared

make

make install

但当我运行MPI程序时，出现了一个错误：

./exe_framework: error while loading shared libraries: libmpi.so.1: cannot open shared object file: No such file or directory

然后，我将LD_LIBRARY_路径修改为：/usr/mpich2 install/lib。但错误仍然存在。我选中了/usr/mpich2安装/lib。ls的输出为：

没有libmpi.so。我以前安装过openMPI。现在我用makeuninstall删除了它。libmpi.so.1是openmpi/lib中的一个文件

路径是：

/usr/mpich2-install/bin/:/usr/mpich2-install/bin/:/usr/mpich2-install/bin/:/usr/openmpi-install/bin/:/usr/openmpi-install/bin/:/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin

LD_库_路径为：

/usr/mpich2-install/lib/

ldd exe_框架是：

    linux-vdso.so.1 =>  (0x00007fff33bff000)
    libpthread.so.0 => /lib64/libpthread.so.0 (0x00000036f1e00000)

安装过程中我错了吗？

您必须使用MPICH2提供的

mpicc

（或

mpif90

或任何编译器包装器）重新编译可执行文件。它不起作用。“which mpicc”的输出是“/usr/mpich2 install/bin/mpicc”，我重新制作了整个MPI程序。编译命令是：“/usr/mpich2 install/bin/mpicc*.c../common/*.c-O0-o exe_framework-g-lpthread-lm-rdynamic-Werror”。错误仍然存在。

ldd exe_framework

的输出是什么？哦。评论太长了。我把它加在了问题的底部。哦！我试着在两台机器上运行它。我刚刚修改了一台机器的设置！我需要设置另一台机器。另一台计算机没有正确版本的MPICH2。
