Question

我一直在尝试构建HPL但没有成功。我已经安装了Open MPI并且运行正常。我也有BLAS库。但是当我尝试构建时，我会遇到一些与openmpi相关的错误。例如，我发现＆＃34; opal_install_dirs＆＃34;是来自libopen-pal的符号。但我不知道这些未定义的引用来自何处，所以我不知道如何解决它。

这只是make输出的结尾部分。

在HPL的配置文件中，我有：

MPdir        = /usr/local
MPinc        = $(MPdir)/include
MPlib        = $(MPdir)/lib/libmpi.a
...
LAdir        = /usr/lib/libblas
ifndef  LAinc
LAinc        = 
endif
ifndef  LAlib
LAlib        = $libblas.a
endif
...

# On some platforms,  it is necessary  to use the Fortran linker to find

LINKER       = $(CC)
LINKFLAGS    = $(CCFLAGS)  
#
ARCHIVER     = ar
ARFLAGS      = r
RANLIB       = echo

我在那里尝试了不同的选项，从我在几个帖子和论坛上找到的信息，我找到了其他一些以前的错误，但我找不到任何解决这个问题的方法。有人能看出可能出错的地方吗？感谢。

Answer 1

我通过简单地使用libmpi.so而不是libmpi.a解决了这个问题，但我不确定它的区别是什么。我之前看到的大多数配置示例都使用了* .a库，除了使用libmpi.so的那个。

Answer 2

我通过将MPinc和MPlib设置为清空字符串来解决问题
