我想做的是为Linux机器生成一个静态MPI可执行文件。源代码是用C ++编写的。当我使用gcc -static编译代码的串行版本并在可执行文件上运行ldd时，没有显示任何库。
但是，当我尝试使用MPI时，某些库不是静态链接的。我已经使用下面的shell命令在机器上构建了openmpi。我还看到没有静态链接到可执行文件的完全相同的库也没有静态链接到openmpi构建。在openmpi构建结束时，我得到

我觉得我应该使用的命令链是
tar -xvf openmpi-4.0.1
cd ./openmpi-4.0.1
./configure --prefix="$HOME/.openmpi" --without-memory-manager CXX=g++ CC=gcc LDFLAGS=--static --disable-shared --enable-static
make
sudo make install
export PATH="$PATH:$HOME/.openmpi/bin"
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$HOME/.openmpi/lib/"
cd application/directory/build
cmake ..
make application
我希望能够在使用MPI编译后运行ldd application，并且没有与该应用程序关联的动态链接库。
