c++ - 如何构建静态 C++ openmpi 应用程序？

问题描述

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。当我编译代码的串行版本时，使用gcc -static, 并ldd在可执行文件上运行它显示没有库。

但是，当我使用 MPI 尝试此操作时，某些库没有被静态链接。我已经在我的机器上构建了我的 openmpi，请参见下面的 shell 命令。我还看到，没有与可执行文件静态链接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

/home/bevan/Downloads/openmpi-4.0.1/opal/.libs/libopen-pal.a(dl_dlopen_module.o): In function `dlopen_open':
dl_dlopen_module.c:(.text+0x413): warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking

我觉得我应该使用的那种命令链是，

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ldd application在使用 MPI 编译后运行，并且没有与应用程序关联的动态链接库。
